Steel Billet Induction Heating Machine: Advantages for Pre-forging Through-heating

Forever Electromechanical

Introduction

Traditional flame furnaces and resistance furnaces have long been widely used for steel billet heating before forging. However, they suffer from uneven internal and external temperature, heavy oxidation loss, high energy consumption and poor automation compatibility. As the metal forging industry moves toward low-carbon, intelligent and high-precision manufacturing, the steel billet induction heating machine developed by Forever Electromechanical has become the preferred heating solution for pre-forging through-heating. Relying on IGBT induction power supply and closed-loop infrared temperature monitoring, the equipment achieves uniform internal and external heating of steel billets, perfectly matching automatic forging and skew rolling production lines for steel balls, shafts and other forged parts.

Uniform Through-heating Guarantees Forging Quality

The core requirement of pre-forging heating is consistent temperature across the billet cross-section. Forever Electromechanical’s IGBT induction heat treatment systems generates heat inside the steel billet through electromagnetic induction instead of transferring heat from outside. The cross-section temperature difference can be controlled within ±8℃, avoiding the common defect of hot surface and cold core in flame furnaces. Uniform through-heating stabilizes the metallographic structure of steel materials during deformation. It effectively reduces cracking, folding and rebound in subsequent forging and rolling processes, improving the mechanical performance and qualification rate of finished forgings. Less temperature fluctuation ensures repeatable product quality for mass continuous production.

Fast Heating & Low Oxidation Reduce Material Waste

Induction heating heats billets from room temperature to forging temperature within tens of seconds to several minutes, far faster than traditional furnaces which need 30 to 90 minutes. Short high-temperature exposure greatly cuts oxide scale and decarburization. The metal burning loss is significantly decreased, raising material yield and lowering raw material cost for forging plants. The fast heating cycle also matches the rhythm of fully automatic forging lines. There is no need to keep the furnace warm during intermittent production, eliminating idle heat loss and improving workshop overall equipment efficiency.

Energy-saving & Low-carbon Operation

Adopting optimized resonant frequency conversion modules, the Forever Electromechanical steel billet induction heating machine removes no-load power consumption. Its thermal efficiency exceeds 95% and power factor stays above 0.95. Comprehensive power consumption drops by 20%-30% compared with old heating furnaces. The equipment runs without open flame, flue gas or dust emission. It meets strict environmental standards in many countries. The compact footprint saves workshop space. Factories can integrate it into existing production lines without large reconstruction.

Intelligent Closed-loop Control for Stable Continuous Production

The system is equipped with automatic feeding, servo conveying and real-time infrared pyrometer. It dynamically adjusts output power and conveying speed according to billet size, material grade and incoming temperature. Multiple sets of process parameters can be saved for one-click switching between carbon steel, alloy steel and bearing steel. Built-in over-current, over-voltage, over-temperature and water shortage protection ensures safe 24-hour continuous operation. Remote monitoring and fault early warning reduce manual operation and maintenance workload.

Wide Compatibility with Diverse Forging Projects

Forever Electromechanical’s induction heating machine supports billets from 40mm to 400mm in cross-section and 0.5m to 12m in length. It covers forging preheating for steel balls, piston rods, flanges, auto parts and mining components. It can connect seamlessly with skew rolling lines, forging presses and heat treatment equipment. Customized designs are available to meet different hourly output requirements ranging from 1 ton to 50 tons.

Conclusion

Pre-forging through-heating determines the final quality and production cost of forgings.
