YZ200t Ladle Overhead Crane para sa High-Temperature Molten Metal Handling sa Steelmaking Workshops

Customer Profile – MCC Oriental

MCC Oriental is a leading engineering and equipment supplier in the metallurgical sector, specializing in the construction and upgrading of large-scale steelmaking plants. The company provides integrated solutions covering steelmaking, continuous casting, rolling, and metallurgical logistics.

To enhance the efficiency and safety of molten metal transportation in its steelmaking workshop, MCC Oriental partnered with DAFANG CRANE to introduce an advanced heavy-duty sandok sa itaas na kreyn system.

Project Overview – YZ200t Ladle Overhead Crane

To upgrade molten metal handling, MCC Oriental adopted the DAFANG YZ200t Ladle Overhead Crane, designed with a four-girder, four-rail twin-trolley structure.

Key specifications include:

• Span: 28 m
• Lifting Height: 22 m (main trolley) / 24 m (auxiliary trolley)
• Hydraulic Synchronous Hoisting System: 5 lifting points, synchronization error ≤0.1 mm
• Dual Operation Modes: Wireless remote control + cabin operation
• Standards Compliance: GB/T 3811 crane design code, ISO 12482 safety monitoring
• Environmental Adaptation: Optimized for high-temperature and heavy-dust metallurgical environments

This system enabled the customer to achieve breakthrough performance in molten metal transfer operations.

Mga Pangunahing Sitwasyon sa Application

Hot Metal Ladle Transfer

• Task: Handling 180-ton hot metal ladles (Ø 3.5 m, H 4.5 m)
• Hydraulic synchronous hoisting + laser alignment
• Lifting time reduced from 2.5 hours to 55 minutes
• Verticality deviation controlled within 1/1000

Steel Billet Continuous Casting

• Task: Lifting 100-ton billets (14 m × 1.8 m) during continuous casting
• Four-girder design minimizes deflection
• Smooth operation with 35% reduction in scrap rate

Multi-Crane Coordinated Operation

• Task: Synchronous lifting of two continuous-casting billets (90 tons each)
• Precise synchronization of speed and position
• Operational efficiency +45%
