Pont roulant de fonderie YZ200t pour le levage de grandes poches de coulée dans la sidérurgie

Customer Company Background

Baogang Group (Inner Mongolia Baotou Steel) is one of China’s major state-owned iron and steel enterprises, known for its large-scale steelmaking capacity and demanding production environment featuring high temperatures, heavy workloads, and continuous casting operations. To support its ongoing modernization and intelligent manufacturing objectives, Baogang Group sought advanced lifting solutions capable of enhancing safety, efficiency, and stability in molten metal handling.

Project Overview

Baogang Group adopted Dafang Crane’s YZ160t Foundry Overhead Crane to upgrade molten metal handling in its steelmaking workshop. The crane features a hydraulic synchronous hoisting system, intelligent monitoring platform, and a four-girder, four-rail structure. These technologies significantly improved lifting efficiency and operational safety, offering an “efficient, safe, and green” logistics solution for metallurgical production.

This project accelerates the application of large-tonnage cranes in ultra-high-temperature metallurgy and stands as a benchmark for industry technological upgrades.

Equipment Profile

The YZ160t foundry crane used by Baogang Group includes:

• Structure: Four-girder, four-rail double-main-girder design
• Span: 28 m
• Lifting Height: 22 m (main trolley) / 24 m (auxiliary trolley)
• Hoisting System: Hydraulic synchronous lifting with five lifting points (synchronization error ≤ 0.1 mm)
• Control Modes: Wireless remote control + operator cabin
• Standards: GB/T 3811 design standard, ISO 12482 safety certification
• Working Conditions: Designed for extremely high temperature and heavy dust metallurgy environments

Core Application Scenarios

Hot Metal Ladle Transfer

• Task: Lifting 140-ton molten iron ladles
• Result: Hydraulic synchronous system + laser alignment
• Reduces lifting time from 1.5 hours to 40 minutes
• Vertical deviation controlled within 1/1000

Continuous Casting Billet Handling

• Task: Handling 80-ton billets (length 10 m, width 1.2 m)
• Result: Four-girder four-rail design minimizes deflection
• Casting operations stable with no sway
• Scrap rate reduced by 28%

Multi-Crane Synchronous Operations

• Task: Dual-crane synchronous lifting of two casting billets (70 tons each)
• Result: Coordinated control of speed and position
• Efficiency improved by 38%
• Energy consumption reduced by 22%

Technical Innovations

Hydraulic Synchronous Hoisting System

• Integrated proportional valves + displacement sensors
• Millimeter-level synchronization across 5 lifting points
• Emergency manual pump ensures safe lowering in power loss

Intelligent Safety Monitoring
