It is a special crane for the core of the foundry workshop.
Engineering for 800°C Radiant Heat
During the pouring and transportation of molten steel in the foundry, the high-temperature molten steel continuously releases high-intensity radiant heat at 800℃, which will quickly cause deformation of metal components of ordinary cranes, aging of rubber cables, failure of electrical components, and failure of lubricating oil carbonization. Major safety accidents such as leakage of molten steel and falling loads will be caused.Henan Mine Crane Factory supply 32t foundry ladle cranes has targeted a full set of 800℃ radiant heat protection projects. As a high-temperature-resistant explosion-proof crane, the heavy-duty and high-temperature-resistant 32t foundry ladle cranes has built a comprehensive high-temperature-resistant operation system from the three dimensions of component protection, material selection, and heat insulation of the electronic control system to ensure that this heavy-duty casting crane can operate stably under high temperature conditions for a long time.
Thermal protection of crane components
The core load-bearing and moving components of the whole machine adopt a layered thermal insulation and protection structure to completely isolate the penetrating damage of 800℃ radiant heat.The main beam, end beam, reel, pulley block and other core metal components of this special casting crane are sprayed with a special high-temperature thermal insulation coating on the surface. The coating can effectively block high-temperature radiation and avoid thermal fatigue deformation and strength degradation of the metal substrate due to long-term high-temperature baking. Problems.For the lifting operation area directly above the ladle, this high-temperature crane is equipped with detachable high-temperature thermal insulation panels to form a physical thermal insulation barrier to block direct high-temperature heat sources.
At the same time, the equipment optimizes the heat dissipation structure of the components, and reserves ventilation and heat dissipation channels in the heavy-duty parts to achieve passive air-cooled heat dissipation and avoid heat accumulation.For precision moving parts such as bearings, gears, pins, etc., a special lubricating medium for high temperature resistance is used, which can withstand high temperature conditions in a radiant heat environment of 800℃, eliminate grease carbonization, dry wear and wear of components and other failures, ensure the stability and flexibility of the mechanical transmission structure of this metallurgical crane, and greatly reduce the equipment failure rate of the crane in a high temperature environment.
Heat-resistant materials and insulation
The materials of the whole mechanism have been adapted and selected for high-temperature working conditions, abandoning ordinary carbon steel and general-purpose accessories, and adopting a full set of industrial-grade high-temperature-resistant special materials, which are suitable for long-term operation needs of 800℃ radiant heat.The main load-bearing structure is made of high-strength heat-resistant alloy steel, which has excellent high-temperature strength, thermal deformation resistance and fatigue resistance. Under continuous high-temperature radiation environment, there will be no deformation, cracking and other problems, and it professionally guarantees the structural stability and operational safety of this 32-ton casting crane for heavy-duty lifting.
The thermal insulation filling material adopts multi-layer composite high-temperature-resistant thermal insulation cotton, with a flame-retardant thermal insulation sealing structure, stable thermal insulation performance, high flame-retardant grade, and sustainable blocking of high temperature conduction.The steel wire rope adopts high-temperature-resistant steel core steel wire rope, abandoning ordinary fiber core material, avoiding high-temperature burning and aging, greatly improving tensile strength and high-temperature resistance, and adapting to the high-risk working conditions of molten metal hoisting.All sealing and cushioning accessories are made of high-temperature and flame-retardant rubber materials to prevent high-temperature softening, aging and cracking, and improve the overall heat resistance level and service life of the equipment in all directions.
Protection of electrical and control systems
The electrical and control system is the core brain of the crane, and it is also the most vulnerable component in a high temperature environment.For 800℃ radiant heat conditions, this 32t foundry ladle cranes, as a special metallurgical crane for industry, adopts an independent closed electronic control cabin design. The core electrical components such as electronic control cabinets, frequency converters, and PLC controllers are centrally arranged in a sealed electronic control room. The electronic control room is equipped with a special pressurized cooling system and industrial air conditioning to achieve constant temperature and heat insulation protection, isolate the intrusion of external high-temperature heat sources, and ensure the stable operation of the crane's electronic control system.
The complete set of cables of the equipment adopts high-temperature and flame-retardant special cables, which can withstand high-temperature radiation for a long time without aging, short-circuiting, and leakage. The circuit joints are treated with high-temperature insulation and sealing to prevent poor contact with high-temperature oxidation.At the same time, the control system is equipped with a high-temperature real-time monitoring module, which can dynamically collect the operating temperature of the electronic control system, cables, and components. Once the temperature exceeds the safety threshold, the system automatically triggers an early warning and initiates a heat dissipation protection program to avoid the root cause of high temperature caused by electronic control failure, equipment out of control problems, to ensure accurate control and stable operation of the whole machine.
Dual Emergency Brakes for Critical Load Safety
Molten molten steel is a high-risk heavy load. Once the 32-ton molten steel drum fails to brake and the load slips, it will cause devastating equipment damage, casualties and production losses.To this end, Henan Mine Crane Factory supply32t foundry ladle cranes is equipped with a dual emergency brake redundant safety system, using the main and auxiliary independent braking architecture to achieve multiple lock-in protection, which can cope with various abnormal working conditions such as power failure, mechanical failure, and electronic control failure. It is the core safety guarantee under high-risk working conditions of casting.The complete braking system has passed the three-level safety certification, and has the advantages of automatic fault locking, zero slippage, and extremely fast response, completely eliminating the safety hazards of heavy-duty lifting.
Primary and secondary braking systems
The dual emergency braking system consists of two independent mechanisms, the main braking system and the backup auxiliary braking system. The two systems have no linkage dependence, independent power supply, independent control, and do not interfere with each other and are backed up by each other.The main braking system is a conventional operating braking mechanism, which adopts a hydraulic disc braking structure, with fast response speed and stable braking. It is responsible for the normal lifting, landing, start-stop, limit braking and other conventional working conditions of the crane. The braking accuracy is high, and it can achieve a smooth start and stop of 32 tons of heavy loads to prevent the steel ladle from shaking and shifting.The auxiliary emergency braking system is a purely mechanical spring braking structure, which is a passive safety protection device, does not require electric drive, and relies on mechanical elasticity to achieve locking braking.Under normal operating conditions, the auxiliary braking system is in a standby state and does not participate in conventional braking.When the main brake system fails, fails or is powered off, the auxiliary brake system will automatically activate instantly, without manual intervention throughout the process.The dual protection of the two sets of brake systems completely solves the industry shortcoming of insufficient reliability of the single brake structure, and greatly improves the safety factor of high-risk lifting conditions.
Emergency braking under abnormal conditions
In view of various sudden and abnormal working conditions in the foundry workshop, the dual emergency braking system can realize rapid response and intelligent locking in the whole scene.In emergency situations such as sudden power failure, electronic control system failure, main brake hydraulic failure, abnormal transmission mechanism, etc., the system recognizes danger signals at the millisecond level, immediately triggers the emergency braking program, and instantly locks the lifting reel and operating mechanism to prevent the molten steel from falling out of control and slipping.At the same time, the equipment is equipped with an intelligent discrimination system for abnormal working conditions, which can accurately identify dangerous states such as overload, overspeed, slip hook, tilt offset, etc., predict risks in advance and take the initiative to activate emergency braking.Compared with the single passive braking of ordinary cranes, the dual emergency braking system of this equipment can realize the dual protection of active early warning and passive locking. Regardless of electrical failure or mechanical failure, it can ensure that the equipment is stopped immediately under abnormal working conditions, the load is stably locked, and the high-risk operation risks are avoided in all directions.
Redundant load-holding protection
In order to completely eliminate the hidden dangers of heavy-duty slippage, the equipment has added multiple redundant load protection mechanisms on the basis of a dual braking system to build a multi-layer safety defense line.In addition to the main and auxiliary dual brakes, the lifting mechanism is equipped with a special load locking device, which can lock the rotation of the reel twice after the brake is locked to achieve double locking and eliminate micro-slippage caused by brake relaxation.At the same time, the wire rope anti-slotting device, the limit protection device, and the overload protection device are synergistically linked to form a complete closed loop of safety protection.The complete set of redundant protection system does not require manual operation, and the whole process is automated. Even if a single protective component fails, the remaining protective mechanisms can still independently complete the safety locking operation, ensuring that the 32-ton molten steel package has zero slippage and zero offset during the whole process of floating and standing, transportation, start and stop. It is perfectly adapted to the uninterrupted, high-load and high-risk production conditions of the foundry industry, and meets the stringent safety specifications of the metallurgical industry.
