Henan Mine 450t Four-Girder Four-Girder Casting Crane—Smart Benchmark for Electric Arc Furnace Steelmaking

Casting cranes serve as the “heavy-duty core equipment” in electric arc furnace steelmaking processes. Their lifting capacity, span, safety, and intelligence directly determine the efficiency and safety baseline for molten metal handling in large steel enterprises. Centered on “Premium Intelligent Manufacturing + Technological Breakthroughs,” Henan Mine’s 450t Four-Girder Four-Girder Casting Crane stands as China’s benchmark model for electric furnace steelmaking—featuring the highest lifting capacity, most advanced technology, and widest span. Tailored specifically for molten metal handling, it has earned unanimous acclaim from metallurgical industry users.

I. Core Benchmark Project

1. Project Overview: The Ultimate Demand for High-End Electric Furnace Steelmaking

A major metallurgical enterprise focused on upgrading its high-end electric furnace steelmaking capacity required a foundry crane capable of handling “ultra-heavy loads, large-span operations, and ultimate safety” for critical molten metal transfer in its steelmaking and ironmaking plants. This necessitated near-demanding requirements for equipment reliability, safety, and intelligence.

To address this core need, Henan Mine custom-engineered the 450t Four-Girder Four-Girder Foundry Crane. Perfectly aligned with electric furnace steelmaking process characteristics, it became the project’s core lifting equipment for molten metal transfer, completely resolving the safety and efficiency challenges faced by traditional cranes in ultra-heavy-load, long-span scenarios.

2. Core Product Advantages

This 450t Four-Girder Four-Girder Casting Crane for Electric Furnace Steelmaking employs comprehensive technological innovation to overcome heavy-load lifting challenges, delivering core advantages across four dimensions: “Safety, Durability, Intelligence, and Efficiency.”

• Four-Girder Four-Girder Structure: Reinforcing Heavy-Load Safety Defenses: Utilizing an integrated large-reduction gear arrangement with four girders and four rails, it achieves a 50% safety improvement over traditional double-girder or triple-girder designs. The large-span design perfectly accommodates the layout of large electric furnace steelworks, maintaining stable operation even under peak 450-ton loads. It completely eliminates the risk of structural deformation during heavy-duty operations, setting the standard as a high-safety four-girder, four-rail crane for molten metal handling.
• Integrated Machining Process Extends Equipment Lifespan: The trolley frame undergoes full annealing and integrated machining to completely eliminate processing stresses. Overall assembly precision exceeds industry standards by 30%, with operational vibration controlled within 3mm. This ensures stable molten metal handling while extending equipment lifespan by 40% compared to similar products, significantly reducing customer maintenance costs.
• Finite Element Modeling Analysis for Enhanced Structural Strength: Advanced finite element modeling analysis is employed during design, applying equal strength and equal lifespan principles to components. This achieves perfect structural-mechanism integration, meeting 450-ton heavy-load demands while optimizing equipment weight and energy consumption. Its cost-performance ratio far surpasses industry peers, establishing it as the high-value solution for large-tonnage foundry cranes.
• PLC Intelligent Control with Upgrade Potential: Equipped with a PLC control system and open industrial Ethernet bus, the crane reserves intelligent upgrade interfaces. This supports future integration with customer digital production platforms, enabling functional expansion and technological iteration—aligning with the trend toward intelligent upgrade-ready heavy-duty foundry cranes.
• Lifecycle Safety Monitoring for Efficient Control: Equipped with a dedicated safety monitoring management system, it enables real-time safety alerts, comprehensive operational data logging, and full-lifecycle inspection traceability. This ensures safe handling of molten metal while boosting production efficiency.

3. Industry Reputation

Upon commissioning, this 450t four-beam, four-rail foundry crane has become the global technical benchmark for heavy-duty foundry cranes in electric furnace steelmaking processes. Its “high reliability, high safety, high configuration” performance perfectly meets the core requirements for molten metal handling in electric furnace steelmaking.
