Electromagnetic Heating Machine for Thick Iron Bar Hot Heading in China Factory - Leading Suppliers of Induction Heating Solutions
Product Description
Compared to traditional resistance furnaces, it offers significant energy-saving benefits, achieving up to 30%-50% reduction. The precise temperature control system (±10°C) effectively prevents oxidation and decarburization, enhances the density and grain refinement of forgings, and reduces mold thermal stress, extending the service life of molds by 40%. Additionally, the equipment features a PLC intelligent control system, with support for parameter memory, fault diagnosis, and industrial Internet of Things interfaces, fulfilling the automation requirements of modern forging production lines, and is particularly well-suited for the mass production of high-precision irregular parts.
Application Scope
Widely applied in the through-heating and temperature compensation of materials such as bar stock, round steel, square steel, and steel plates, as well as online heating and local heating. It plays a significant role in the online forging of metal materials (e.g., gears, semi-axle connecting rods, bearings, and other precision forging), extrusion, hot rolling, heating before shearing, heating for spraying, and hot assembly processes. Additionally, it is used in the heat treatment processes of metal materials, including overall tempering, annealing, and tempering.
Configuration and Performance
Power Supply & Coil Design
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.
Smart Control & Cooling
Integrates a 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.
Rapid & Uniform Heating
Heats Ø60mm iron bars to 1200°C within 90 seconds while maintaining temperature uniformity within ±5°C. Electrothermal conversion efficiency exceeds 85% with oxidation loss reduced to 0.3%.
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.
