Heavy-Duty YZ200t Foundry Overhead Crane Applied to Steelmaking and Continuous Casting

고객 배경

Tangsteel Group, a core subsidiary of the Fortune Global 500 HBIS Group, is one of China’s leading integrated steel producers. With strong capabilities in ironmaking, steelmaking, and rolling, the company serves key sectors such as bridges, energy equipment, and heavy machinery. The demanding production environment places high requirements on lifting stability, safety, and long-term reliability.

YZ200t Foundry Overhead Crane Enhancing Molten Iron Ladle Handling Efficiency in Steel Mills

Tangsteel Group achieved a major technological breakthrough in molten metal handling by adopting DAFANG’s YZ200t foundry overhead crane. Featuring a hydraulic synchronous lifting system, intelligent monitoring platform, and four-girder four-rail structure, the crane significantly enhances operational efficiency and safety. This project marks an important step in extending metallurgical crane applications toward ultra-heavy loads and extreme high-temperature conditions.

Equipment Overview

To improve molten metal handling efficiency in the steelmaking workshop, Tangsteel Group introduced the YZ200t foundry crane featuring:

• Four-girder four-rail dual-trolley structure
• Span: 28 m
• Lifting height: 22 m (main trolley), 24 m (auxiliary trolley)
• Hydraulic synchronous lifting system: 5 lifting points, synchronization error ≤0.1 mm
• Control modes: wireless remote control + operator cabin
• Standards: GB/T 3811 design code, ISO 12482 safety certification

Engineered for high-temperature and heavy-dust metallurgical conditions.

Core Application Scenarios

Molten Iron Ladle Transfer

• Task: Lifting a 180-ton ladle (Ø3.5 m, height 4.5 m)
• Result: Hydraulic synchronization + laser alignment cut lifting time from 2.5 hours to 55 minutes; vertical deviation controlled within 1/1000.

Continuous Steel Billet Casting

• Task: Continuous lifting of 100-ton billets (14 m × 1.8 m)
• Result: Four-girder structure reduces deflection, ensures stable continuous casting, and lowers defect rate by 35%.

Multi-Crane Synchronized Operation

• Task: Coordinated lifting of two 90-ton cast billets
• Result: Intelligent coordination system synchronizes speed and position, boosting efficiency by 45% and reducing energy consumption by 28%.

Technological Innovations

Hydraulic Synchronous Lifting System

• Proportional valve + displacement sensor ensure millimeter-level precision
• Emergency manual pump ensures safe lowering during power failure

Intelligent Safety Monitoring

• Real-time monitoring of 15 parameters, including girder stress and leg settlement
• 3D laser anti-collision system (70 m warning range, ±8 cm accuracy)

Extreme Environment Adaptation

• Q460E high-strength steel + double-layer thermal insulation
• Wind resistance up to Grade 13
• Electrical system with IP67 protection for ultra high-temperature and heavy-dust environments

User Benefits & Feedback

• Efficiency Increase: Daily steelmaking output increased from 1,400 tons to 1,900 tons (+35%)
• Cost Reduction: Hydraulic system reduces energy consumption by 38%, saving approx. 2 million RMB annually
• Safety Performance: Zero safety incidents in 6 years; certified to ISO 45001 occupational safety standard
