롤링 워크숍 자재 취급을 위한 스마트 전자기 오버헤드 크레인 솔루션

Lianyuan Steel Overview

Lianyuan Steel, a major state-owned enterprise under the Fortune Global 500 Hunan Steel Group, has an annual production capacity of over 12 million tons. As a leading high-quality steel production base in Central and Southern China, it operates the world’s largest medium and thin-gauge heat-treated plate production line. Its silicon steel base metal output also ranks first in China, with products widely used in landmark projects such as the Hong Kong–Zhuhai–Macao Bridge and Tesla.

To upgrade material handling operations in its rolling workshop, Lianyuan Steel introduced DAFANG’s 전자기 오버헤드 크레인, achieving a significant step toward smart, efficient, and safe steel logistics. Equipped with electromagnetic lifting technology, laser positioning, and an intelligent monitoring platform, the system has greatly enhanced operational efficiency and workplace safety, supporting the steel industry’s move toward standardized and intelligent crane operations.

Equipment Overview

To improve the handling efficiency of the rolling workshop, Lianyuan Steel adopted the QCL-type Electromagnetic Overhead Crane, featuring:

• Double-girder structure
• Rated capacity: 20+20 tons (main & auxiliary hook)
• Span: 28 m
• Lifting height: 22 m
• Electromagnetic lifting disc: Ø 2.2 m, lifting capacity 18 tons
• Operation modes: ground remote control + cabin operation
• Fully compliant with GB/T 3811 crane design standards
• Certified to ISO 12482
• Engineered for high-temperature and heavy-dust metallurgical environments

Core Application Scenarios

Steel Billet Transfer

• Task: Handling hot billets (15 tons each, 12 meters long)
• Result:
• Automatic magnetic gripping system (response ≤ 3 s)
• Intelligent anti-collision for trolley & bridge travel
• Transfer efficiency increased by 60%
• Manual intervention reduced by 80%

Bar Stock Yard Management

• Task: Multi-layer bar bundle stacking (8 tons per bundle)
• Result: Laser positioning accuracy ±10 mm, Yard utilization improved by 40%

Maintenance Assistance

• Task: Lifting rolls and bearing housings (10 tons each)
• Result: Variable-frequency control (0.5–10 m/min lifting speed), Hydraulic anti-sway system, Maintenance safety increased by 75%

Key Technical Innovations

Electromagnetic–Mechanical Dual Drive System

• Redundant power supply with onboard UPS ensures 15 minutes of magnetic holding during power loss
• Optional mechanical grab mode for mixed material handling

Intelligent Monitoring & Early Warning

• Integrated stress, temperature, and collision-avoidance monitoring
• Data transmitted in real time to the central control room via remote supervision platform

Enhanced Structural Safety

• Main girders welded with Q345D steel and reinforced with Q460E high-strength plates
• Equipped with wind-proof anchoring (resistance up to Level 12 winds)

Customer Benefits & Performance Results

• Efficiency Boost: Daily billet throughput increased from 1,200 t → 1,800 t, improving production rhythm by 25%
• Cost Optimization: Electromagnetic lifting consumes 40% less energy than mechanical grabs
  → Annual electricity savings approx. 600,000 RMB
• Safety Performance: Zero safety incidents in four years of operation. Certified to ISO 45001 occupational health & safety standard
