Electromagnetic heating machine for hot heading process of thick iron bar in foundry plant

This electromagnetic induction heating equipment features a high-frequency inverter power supply (380V/50Hz, customizable for 440V/60Hz) and a water-cooled copper heating coil specifically designed for iron bars with diameters of 20-80mm. The control system integrates PLC temperature control module, supported by a dual-channel closed-loop water-cooling system (3m³/h flow rate), ensuring stable operation with overload protection and emergency stop functionality.

‌
The equipment heats Ø60mm iron bars to 1200°C within 90 seconds while maintaining temperature uniformity within ±5°C. With over 85% electrothermal conversion efficiency and oxidation loss reduced to 0.3% (compared to traditional gas furnaces), it significantly improves material utilization and supports 24/7 continuous operation, requiring only 15-minute cooling intervals.

Key performance includes a 120kW maximum power output and 1–20kHz frequency adjustment range, achieving temperature control accuracy of ±1% of the setpoint. The compact unit measures 1200×800×1600mm, facilitating workshop integration. Actual performance may vary slightly based on material properties and environmental conditions.

‌
Ideal for precision hot-heading processes like automotive fasteners and aerospace forgings, the system optimizes metal plasticity through rapid, uniform heating. Its enclosed water-cooled design and automated temperature control significantly reduce energy consumption, complying with ISO 9001 standards, with a 1-year warranty included.

Note: Performance parameters are based on standard operating tests. Users are advised to conduct process validation according to specific production requirements.
