Induction Heating Machine for Hot Rolling Mills - China Suppliers and Factory for Steel Plate Pre-Heating
Product Description
This high-frequency induction heating machine delivers efficient pre-heating (up to 1200°C) for steel plates and iron sheets in hot rolling mills, featuring precise temperature control with ±5°C accuracy through advanced IGBT technology. Its automated system reduces oxidation by 30% while achieving 20% faster heating cycles compared to traditional methods. The ISO-certified equipment integrates seamlessly with existing production lines via PLC interfaces, maintaining uniform heat distribution across 6-ton/hour capacity workpieces.
Application Scope
This induction heating system is specifically designed for hot rolling mill applications, providing efficient pre-heating for carbon steel plates, alloy steel sheets, and structural iron components with thicknesses ranging from 5mm to 150mm. It's widely implemented in steel plants, metal processing facilities, and heavy manufacturing industries for continuous production lines requiring precise temperature control between 800°C to 1200°C before rolling operations. The equipment demonstrates exceptional performance in processing coils, slabs, and billets while maintaining compatibility with both new installations and existing mill retrofits.
Configuration and Performance
The induction heating system features a modular design with IGBT-based power units (200-3000kW adjustable), dual-frequency operation (1-10kHz), and integrated PLC control with HMI interface. Its multi-coil configuration ensures uniform heating across widths up to 2500mm, achieving temperature consistency within ±5°C through closed-loop infrared thermography. The water-cooled copper coils withstand continuous 1200°C operation with 98% thermal efficiency, while the automated material handling system processes 6-8 tons/hour with <0.3% material oxidation. Advanced features include energy recovery systems (saving 15-20% power) and predictive maintenance algorithms that reduce downtime by 30%. The ISO-certified machine demonstrates <1% temperature deviation across workpieces and maintains 95% uptime in 24/7 industrial environments, compatible with Industry 4.0 protocols for seamless MES integration.
