How Vietnam Steel Mills Sourced Casting Cranes

Crane is a high priority lifting equipment in the steel production plant, specially used to complete the lifting of high-temperature molten metal, long-term in a high-risk, heavy-duty, high-temperature special production environment.

In recent years, Vietnam's local steel industry continues to expand, new plants put into operation, the old production line upgrading projects continue to increase, the major steel mills for the procurement of metallurgical casting Crane demand is also rising steadily.

Local steel mills in Vietnam in the process of purchasing steel casting cranes, never only the purchase price as the only criterion. The safety level of equipment operation, the whole machine working level, on-site technical docking ability, as well as the later long-term maintenance and parts supply, are all their key considerations.

Relying on years of hands-on experience in Vietnam's metallurgical market, combined with Henan Mine Crane service in Vietnam Yishan Steel, Ha Jing Steel and other local head of the steel plant landing cases, we sorted out the local steel mills to select the overall procurement of molten metal lifting cranes, technical screening criteria and supplier judgment logic, but also to the global procurement of similar metallurgical projects to provide a practical reference for ideas.

Casting Cranes in the core role of steel plants

Undertake the core process of molten metal transfer

In the whole set of steel smelting production process, casting Crane is mainly responsible for ladle lifting, high-temperature molten steel field transfer, and at the same time with the completion of key processes such as casting molding.

The operation status of this type of equipment, directly linked to the ironmaking, steelmaking, continuous casting and other core production links, is the entire production line can not be replaced by the basic lifting equipment.

Safety standards are much higher than ordinary Overhead Crane

Casting Cranes work under the high-risk environment of high temperature radiation, dense smoke and dust, and frequent lifting and lowering of heavy loads for a long time.

The industry has developed exclusive safety design standards for metallurgical scenarios, whether it is the structure of the material or protection configuration, than the workshop ordinary traveling crane has more stringent requirements.

Directly affect the overall capacity of the steel plant

Once the casting Crane is down, it will directly lead to the steelmaking furnace can not be normal steel, casting process is forced to interrupt.

The entire production line will come to a standstill, not only delay the production program, but also cause a series of collateral losses such as raw material loss, manpower idleness.

What is a casting Crane

Basic definition

Casting Crane belongs to the heavy-duty special-purpose overhead cranes, which are specially developed and manufactured for iron and steel mills, large foundries, and are used to lift all kinds of high-temperature molten liquid metal special lifting machinery.

Distinguished from general lifting equipment, all of its design ideas are centered on high-temperature working conditions and heavy-duty operation of the two core directions to build.

Mainstream structure and configuration features

The mainstream double girder casting cranes on the market have the widest range of applications, and some large-tonnage heavy-duty scenarios will also use the four-beam structural design.

The equipment is equipped with a standard combination of main and auxiliary double hooks, which can be adapted to the lifting and fine-tuning operations of different tonnages of steel ladles. The whole machine is equipped with high-temperature resistant protective structure, braking system, electrical control system have made special heat-resistant upgrades, while installing multiple safety protection devices.

The Difference Between Casting Crane and Overhead Crane

The most intuitive difference between the two is reflected in the work level, casting Crane all choose high-grade heavy-duty work system, to meet the needs of non-stop high-frequency operations throughout the day.

In the core safety components, the casting Crane will do redundant design, to enhance the fault tolerance rate of equipment operation. The overall steel structure is made of thicker materials, and all the parts and components are suitable for high-temperature metallurgical scenes, which can not be replaced with ordinary workshop cranes.

Why Vietnam’s steel mills should use professional casting Crane

Expansion of the local steel industry to drive equipment upgrades

Vietnam's local infrastructure industry continues to develop, directly pulling the steel market demand rose, a large number of new steel plants landed one after another, the original old plant is also expanding capacity.

Older models of ordinary lifting equipment has been unable to match the operating rhythm of modern steel production lines, the market is in urgent need of a large number of special steel mill cranes suitable for high temperature working conditions.

Plant production on the operation of a higher demand for safety

With the steel industry production norms continue to improve, the local steel mills pay more and more attention to the production site operation risk control.

Traditional simple lifting equipment safety configuration is insufficient, it is difficult to avoid all kinds of unexpected hidden dangers in the process of steel lifting, professional casting Crane has become a mandatory configuration of the plant safety production.

Procurement concept gradually favoring the comprehensive quality

Earlier years, some of the local small-scale steel mills procurement equipment, will prioritize the purchase of low budget.

Now more than large-scale steel mills procurement ideas have changed significantly, no longer focus on low prices, more important to the overall design level of the equipment, the ability to adapt to the site and long-term operational stability, procurement ideas are becoming more and more mature.

Vietnam steel mills procurement of casting cranes core concerns

Field operation safety performance

Multiple redundant braking structure is the focus of the procurement audit, with overload limit protection devices, from the hardware level to avoid the risk of overloading operations.

At the same time, the equipment needs to have a perfect emergency braking response mechanism, lifting control logic is simple and precise, to minimize the potential safety hazards caused by human operation.

Heavy load continuous operation ability

Equipment needs to have a long time continuous operation ability, lifting and running smoothly without obvious shaking, large and small car traveling smooth and smooth.

The whole structure of the machine can withstand the long term high temperature in the factory baking, dust accumulation and other external influences, will not because of the poor working conditions of the operation of the jam, accelerated aging of components and other issues.

Long-term stability of the machine

Vietnam steel mills prefer to choose models with mature structural design and many market applications, and prioritize checking the durability of the load-bearing structure of the whole machine.

At the same time, we focus on checking the market reputation of the core components to reduce the probability of failures at the later stage and ensure the stable operation of the production line.

Complete supporting technical data and technical support

Formal and complete equipment diagrams, load data, electrical wiring drawings, are plant equipment acceptance, daily maintenance of the necessary information.

In addition, equipment instruction manuals and a full set of factory inspection documents are also required to facilitate daily access by plant operation and maintenance personnel.

Core technical parameters to be verified in Vietnam steel mills

Rated lifting capacity

According to the specifications of the steel ladle used in the plant and the actual weight of fully loaded steel, the rated lifting tonnage of the main hook of the equipment should be determined, and a reasonable safety margin should be reserved.

Equipment span

Combined with the width of the steelmaking workshop and the center distance of the track, the overall span of the Crane is accurately matched to ensure that the walking range of the equipment is in line with the on-site production layout.

Effective lifting height

Combined with the height of the steelmaking furnace discharge, the height of the steel ladle transfer parking height and the height of the casting operation, to meet the space requirements of the whole process lifting operations.

Equipment working level

Metallurgical casting scene must choose high working level model, suitable for daily long time, high frequency of repeated lifting operations, which is also the key index to distinguish between professional equipment and ordinary equipment.

Running speed parameters

Lifting speed, trolley running speed, trolley running speed need to be reasonably deployed, in order to protect the operational efficiency, while taking into account the smoothness of the steel lifting process, to avoid liquid metal shaking and spilling.

On-site working conditions

Confirm in advance the perennial ambient temperature of the plant, the intensity of heat radiation generated by smelting operations, the concentration of dust in the workshop, as well as slightly corrosive gases generated in the production process.

Adjust the equipment protection level and heat-resistant configuration according to the actual working conditions, so that the equipment is fully adapted to the site environment.

How to screen casting crane suppliers in Vietnam steel mills

On-site verification of the manufacturer’s manufacturing strength

The local procurement team is more inclined to choose the entity with its own production workshop casting Crane manufacturers, simple trade intermediary is difficult to become the preferred partner of large steel mills.

Purchasers will focus on checking the manufacturer's large-scale steel processing equipment, complete machine assembly line, to confirm that the manufacturer has the hardware conditions for independent production of large-tonnage metallurgical lifting equipment. At the same time will verify the manufacturer's local landing performance, such as Henan Mine Crane in Vietnam landed a number of sets of large-tonnage casting cranes, the whole plant metallurgical lifting supporting projects, are the core of the purchaser focus on reference basis.

Verification of similar projects in the same industry landing experience

Mature steel plants, large casting plant past supply cases, is an important basis for Vietnam steel mills to screen partners.

The same tonnage, the same working conditions of the actual application cases, far more convincing than the written promotional materials. Henan Mine Crane's Vietnam landing project, for example, we have delivered 100/30T large-tonnage metallurgical casting cranes for Vietnam's Hoa Jing Steel, more than 60 sets of complete sets of steel lifting equipment for the Yishan Steel VAS Group, adapted to the high temperature and high humidity of Vietnam's domestic, coastal salt spray, special conditions, the real cases can be visual proof of the manufacturer's actual conditions of the ability to adapt.

Evaluation of manufacturers of specialized engineering design capabilities

Excellent supplier manufacturers can combine the steel plant's own production line layout, lifting process, the local structure of the equipment, operation configuration to make targeted adjustments to optimize.

Instead of directly applying the uniform drawings for mass production, the maximum degree of equipment to adapt to the plant's exclusive production rhythm.

Examination of the manufacturer’s complete quality control process

From the raw materials into the warehouse quality inspection, to the steel structure welding flaw detection, and then to the whole machine empty, full load load test, the whole set of quality control process is perfect or not will be verified one by one.

At the same time, we confirm that the source of core components can be traced to ensure that the quality of each piece of factory equipment is uniform and up to standard.

Confirmation of technical service and spare parts supply

Vietnam is far away from the domestic source of goods, after-sales response speed, the efficiency of cross-border delivery of commonly used perishable parts are all the contents that must be finalized before signing the procurement contract.

A stable after-sales system can minimize equipment downtime and production losses.

The practical value of similar projects in the steel industry

Casting Crane industry is highly specialized

The manufacturing experience of general cranes in ordinary plants can not be applied to molten metal lifting equipment.

Manufacturers who are not familiar with the working conditions of the metallurgical industry, the equipment designed is prone to insufficient protection, unstable operation and other practical problems.

Industry veteran manufacturers are familiar with the site of all kinds of risks

Manufacturers who are deeply engaged in the field of metallurgical lifting equipment and the Vietnamese market are well aware of the key points of protection of electrical components under high temperature environment and the loss pattern of the braking system under high-frequency operation. Henan Mine Crane in the service of Vietnam Yishan, Ha Jing and other steel plant projects, for Vietnam's perennial high temperature, rain, salt spray corrosion of the working conditions of the equipment insulation, dust, corrosion-resistant structure of the special optimization, from the source to avoid premature failure of the equipment, frequent failures and other issues.

At the same time, we are familiar with the actual pain points of dustproof, heat insulation, daily operation and maintenance of equipment in steel mills, so that we can avoid a lot of hidden dangers in the program design stage in advance.

Real on-the-ground cases to enhance procurement trust

Henan Mine Crane Vietnam steel plant cooperation projects, for example, we have retained a complete Hejing Steel large-tonnage casting crane operation data, Yishan Steel plant equipment delivery and acceptance records, the site of perennial operation of the actual photographic material. These real and traceable project information can let the buyer visualize the long-term operation of the equipment in Vietnam under local working conditions, and get rid of the limitation of relying solely on the text to judge whether the product is good or bad.

It allows the purchaser to visualize the actual use of the equipment, and get rid of the limitations of relying solely on text introduction to judge the product good or bad.

Comparison of quotes at the procurement stage of Vietnamese steel mills

Refuse to rely solely on the total price to determine the advantages and disadvantages

Local steel purchasing personnel are well aware of the fact that the program with a low price quotation is likely to reduce costs in terms of core component materials, safety configurations, heat protection and other aspects.

Short-term procurement cost reduction, later production failures occur frequently, the overall operating costs will rise sharply.

Check the offer contains all the contents one by one

The purchaser will carefully comb through the quotation list to confirm whether the quotation includes the main steel structure, a complete set of lifting and running mechanism, a complete set of braking system, and high temperature protection accessories.

Also check whether the electrical control system, exclusive heat-resistant accessories, basic spare parts and factory commissioning services are all included.

Pay more attention to the whole life cycle cost of the equipment

The daily failure rate of the equipment, annual maintenance costs, and the frequency of parts replacement are more important to steel mills than one-time purchasing costs.

Quality standard, reasonably designed casting Crane, can significantly reduce the late hidden expenses, long-term use of more cost-effective.

Core components brand and configuration verification points

Power, brake, electronic control components determine the overall stability of the equipment

Motor, deceleration equipment, brakes and a full set of electrical components, is the most prone to failure of the core components of the casting Crane.

Under the harsh working conditions of high temperature and heavy load, the poor quality parts will quickly deteriorate, directly affecting the safety of the machine.

Metallurgical special scenarios require higher standards for parts

The heat resistance and load capacity of the general parts used in ordinary working conditions are not up to the standards of steel mills and cannot be directly replaced.

During the procurement process, Vietnamese steel mills will explicitly request manufacturers to use specialized accessories suitable for metallurgical heavy-duty scenarios.

Confirm the brands and specifications of all accessories in advance

In the business matching stage, the buyer will ask the manufacturer to list the specific brands, places of origin and model parameters of all core parts.

Eliminate the verbal commitment to high-matching, the actual delivery of low-matching equipment.

Finalize the final cooperation depends on the configuration of the matching degree

Only if the whole set of equipment parts configuration, protection design, operating parameters completely match the actual production needs of the plant, the offer will have practical reference value.

This is also an important basis for Vietnamese steel mills to finalize the cooperation with the supplier.

A full set of technical information is necessary for Vietnam steel mills to purchase.

In the process of equipment acceptance, equipment documentation, daily maintenance and local industry record, the plant needs to provide a complete set of information from the manufacturer.

This includes the overall layout of the equipment, a complete data sheet of technical parameters, and an electrical wiring diagram of the equipment.

At the same time, we also need to provide the whole machine load data, track wheel pressure parameters, all the core components brand detailed list.

In addition, the factory third-party testing and acceptance reports, equipment operation manuals, routine maintenance manuals, are also indispensable documents.

Common Problems in Purchasing Casting Cranes for Vietnam Steel Mills

Difficulty in balancing purchasing budget with site safety standards

Controlling the project procurement investment, and matching a full set of pyrometallurgical safety configurations, has become the most difficult to coordinate in the procurement phase of many small and medium-sized steel mills.

Difficult to determine whether the manufacturer really understand the molten metal lifting conditions

Many lifting equipment manufacturers can produce ordinary traveling crane, but no practical experience in the metallurgical industry, the program given out of the actual use of the scene.

Difficult to compare different manufacturers’ technical solutions horizontally and fairly

Each manufacturer's design ideas, selection of parts standards, structural optimization direction is different, it is difficult for the purchaser to quickly filter out the optimal technical solution.

Equipment standards need to be adapted to the local industry audit norms

Imported equipment needs to comply with Vietnam's local industrial equipment acceptance regulations, all kinds of compliance information to organize the docking, will also consume a lot of communication energy.

Advance planning for equipment installation and commissioning and personnel training

Large metallurgical cranes on-site assembly process is complex, commissioning procedures, if the lack of professional guidance, it is easy to delay the commissioning of equipment use time.

Global steel mills can learn from the experience of purchasing casting cranes

All procurement work is prioritized around their own smelting production process, first clear operational requirements, and then screen the corresponding models, do not copy the model to match the site.

Priority is given to manufacturers with a large number of cases of cooperation with physical steel plants, industry experience is far more important than the scale of production.

Before formally comparing prices, complete the review of all technical solutions, safety configurations, adaptability to working conditions, and prioritize the verification of the manufacturer's real local cases, such as Vietnam steel purchasers generally focus on reference to whether the manufacturer has the same level of experience in projects such as Hoa Binh Iron & Steel and Yishan Iron & Steel, so as to avoid putting the cart before the horse.

In the pre-cooperation period, we will confirm the safety protection design of the equipment and the selection standard of the core components, so as to minimize the trouble of rectification in the later stage.

Before signing the cooperation agreement, finalize the delivery cycle of overseas parts, after-sales technical response, in advance to solve the later operation and maintenance worries.

Steel mills to build a perfect casting crane procurement process

First, we accurately sort out the site lifting needs, clarify the rated capacity of the steel ladle, the actual operating range of the workshop, the site temperature and environment, the daily operating frequency and other basic information.

Organize to form a complete and clear technical specification for equipment procurement, marking the rated tonnage, plant span, lifting height, working level, control mode and all safety configuration requirements.

According to the industry cases and the strength of manufacturers, screen out 3-5 regular casting Crane manufacturers with metallurgical lifting equipment production qualification.

Priority is given to the completion of the horizontal comparison of the technical solutions, to confirm that the structural design, protection configuration, core components all meet the standards, and then carry out commercial price negotiations.

Finally, in the cooperation contract, clearly marked equipment on-site installation guidance, machine commissioning, plant operator training and other ancillary services.

Comparison of actual procurement cases

We can combine Henan Mine Crane real Vietnam steel plant landing project, visual comparison of the core logic of procurement selection. Vietnam Yishan Iron and Steel VAS Group as the local head of the steel industry, had a large-scale bidding steel mill special lifting equipment for steelmaking, rolling the whole process of operation, a number of equipment suppliers to participate in the program and quotation bidding.

Some of the participating suppliers offer lower prices, but there are obvious shortcomings, there is no local steel mill metallurgical project landing experience in Vietnam, high-temperature protection, redundant brakes and other core safety configuration labeling fuzzy, unable to provide special optimization program to adapt to the salt spray, high temperature conditions in Vietnam, and no perfect local after-sales docking system in Southeast Asia.

Henan Mine Crane, as the final cooperative supplier, offer a reasonable range of metallurgical equipment market in Vietnam, high temperature and high humidity, coastal corrosion conditions in Vietnam, the casting Crane insulation protection, electrical sealing, steel structure corrosion prevention to do the exclusive upgrade. The whole machine redundant braking, heavy-duty lifting mechanism, frequency control system configuration is clear and complete, fully adapted to the high-frequency lifting of steel ladle high-risk operating scenarios.

Relying on the mature experience of serving 100-ton casting cranes of Vietnam Ha Jing Iron & Steel and more than 60 sets of complete metallurgical lifting equipment of Yishan Iron & Steel, we are deeply familiar with the production rhythm, acceptance standards and pain points of the working conditions of local steel mills in Vietnam. During the landing stage of the project, we provided a full set of English technical data, full remote installation guidance, on-site commissioning and training services, and at the same time, we built a cross-border spare parts supply channel in Southeast Asia to ensure the long-term stable operation of the equipment.

Yishan Iron and Steel finally finalized the whole plant equipment cooperation with Henan Mine Crane, abandoning the low price and low allocation program. After the commissioning of the equipment, all casting cranes and ancillary metallurgical lifting equipment running smoothly, low failure rate, perfectly adapted to the plant's high-intensity, year-round uninterrupted rhythm of steel production, but also proved that the deep plowing of the local market, manufacturers with real project experience, can bring more stable long-term value for the steel plant.
