Ansteel Group has achieved a breakthrough in molten metal handling technology in steelmaking workshops by using our YZ140t foundry overhead cranes. Featuring a hydraulic synchronous lifting system, an intelligent monitoring platform, and a four-beam, four-rail structure as its core advantages, the equipment greatly improves lifting efficiency and safety, providing an “efficient, safe, and green” logistics solution for the metallurgical industry. This project has promoted the expansion of YZ foundry overhead cranes into ultra-large tonnage and ultra-high temperature applications, becoming a benchmark for technological upgrading in the industry.

Anyang Iron & Steel Group Overview

Founded in 1958, Anyang Iron & Steel Group (Ansteel) is headquartered in Yindu District, Anyang. It has grown into one of China’s leading large-scale integrated steel enterprises. Ansteel is the core steel production base in Henan Province. The Group covers the full industrial chain: mining, coking, smelting, mechanical processing and logistics. It operates advanced production lines, including a 4,800m³ blast furnace and a 1,780mm hot strip mill. Ansteel has built a strategic layout of “one center, four bases, multiple industries.”

Foundry Overhead Cranes Equipment Overview

To improve the efficiency of molten metal handling in steelmaking workshops, Ansteel Group introduced the YZ140t YZ foundry overhead cranes. The equipment adopts a four-beam, four-rail dual-main-girder structure with a span of 25 meters, a lifting height of 20 meters (main trolley), and 22 meters (auxiliary trolley). It is equipped with a hydraulic synchronous lifting system (4 lifting points, synchronization error ≤0.1 mm), and supports wireless remote control and dual-mode cabin operation.
The entire crane complies with GB/T 3811 crane design standards and has passed ISO 12482 safety certification, making it particularly suitable for high-temperature and high-dust environments in the metallurgical industry.

Core Application Scenarios

Iron Ladle Transfer

Task: Hoisting a 120-ton iron ladle (diameter 3 m, height 4 m).
Effectiveness: The hydraulic synchronization system, combined with the laser centering device, shortens the traditional 2-hour lifting cycle to 45 minutes, while maintaining verticality deviation within 1/1000.

Billet Continuous Casting

Task: Continuous lifting of 80-ton billets (length 12 m, width 1.5 m).
Effectiveness: The dual-main-girder structure reduces vertical deflection, ensuring a stable casting process with no shaking, and reduces scrap rate by 30%.

Multi-Crane Cooperation

Task: Simultaneous lifting of two continuous-casting blanks (60 tons each).
Effectiveness: The control system synchronizes the speed and positioning of multiple cranes, increasing operating efficiency by 40% and reducing energy consumption by 25%.

Foundry Overhead Cranes Technological Innovations

Hydraulic Synchronous Lifting System

Integrated proportional valves + displacement sensors achieve millimeter-level synchronization across 4 lifting points;
Equipped with an emergency hand pump to ensure safe landing in the event of sudden power failure.

Intelligent Safety Monitoring

Real-time monitoring of 12 parameters including main girder stress and rail settlement;
3D laser anti-collision system (50 m warning distance, ±10 cm accuracy).

Environmental Adaptability Design

Main girder adopts Q460E high-strength steel plates + thermal insulation layer, with Class-12 wind resistance;
