Henan Mine 32t Intelligent Grab Crane: Empowering Metallurgical Upgrades in Extreme Conditions — Benchmark Case Study-Guangxi Chiji Steel Blast Furnace Project

Intelligent Grab Cranes serve as essential tools for extreme environment operations in the steel and metallurgical industries. Their level of intelligence, environmental adaptability, and stability directly determine the production efficiency and green transformation outcomes of core processes like blast furnaces. Henan Mine, centered on “customized R&D + green intelligence,” has delivered reliable solutions for extreme-condition projects across over 130 countries and regions. The 32t Intelligent Grab Crane custom-built for Guangxi Chiji Steel exemplifies overcoming operational challenges in high-fog, high-temperature, and high-humidity environments, supporting the development of a 10-million-ton metallurgical new materials base. Below is an in-depth analysis.

I. Core Benchmark Project

1. Project Overview: Extreme Conditions Demands for a 10-Million-Ton Steel Base

Guangxi Chiji Steel is committed to establishing a 10-million-ton metallurgical new materials (steel) base. Its 2060m³ blast furnace project is a core initiative for capacity replacement and industrial transformation. The project site faces three major challenges: extreme environmental conditions with year-round high temperatures, humidity, and dense fog leading to extremely low visibility. Traditional cranes often suffer from positioning errors and component corrosion.

To address these high-end requirements, Henan Mine tailored a “full-scenario lifting solution,” delivering 59 units of premium cranes in one batch. Among them, 4 32t Intelligent Grab Cranes (Model 32/5t) were specifically engineered for the 2060m³ blast furnace project, empowering Guangxi Chiji Steel to achieve dual breakthroughs in production efficiency and green transformation.

2. Core Product Advantages

This batch of 32t Intelligent Grab Cranes for Blast Furnaces represents Henan Mine’s premium offerings, custom-engineered for the metallurgical industry’s extreme environments. Their core advantages span four dimensions: “Intelligence, Durability, Adaptability, and Efficiency.”

Smart Integration, Precision Efficiency: Equipped with a PLC control system, high-precision positioning system, and anti-sway control system, achieving positioning accuracy of ±5mm. This perfectly matches the blast furnace process requirements of “continuous operation and precise material feeding,” establishing it as the benchmark model for PLC-controlled intelligent blast furnace grab cranes.

Structurally Durable for Extreme Environments: Featuring a wide-body heavy-duty design, fatigue strength exceeds industry standards by 25%. It withstands triple challenges of high temperature, humidity, and fog, extending component lifespan by 50%. This resolves traditional cranes’ susceptibility to failure and frequent maintenance in harsh conditions, making it the preferred solution for grapple cranes in high-temperature, high-humidity, high-fog environments.

Remote Operation, Green Cost Reduction: Supports remote dispatch management, eliminating the need for on-site operators. Full-process operations can be completed from the central control room, significantly reducing labor intensity and safety risks. The equipment design aligns with green development trends, achieving a 10% reduction in energy consumption compared to traditional counterparts. This supports enterprises in achieving low-carbon production and aligns with the global wave of green transformation in heavy industry.

3. Project Value: A Powerful Alliance Building the Foundation for a 10-Million-Ton Base

This collaboration represents a powerful alliance between Henan Mine and Guangxi ChiJi Steel—59 cranes (sets) comprehensively cover all steel production stages, while 4 32t intelligent grab cranes precisely tackle extreme blast furnace operating challenges. This not only ensures efficient blast furnace project advancement but also earned high recognition from Guangxi ChiJi Steel management, establishing a benchmark for intelligent lifting equipment in extreme metallurgical environments.
