IGBT Billet Induction Reheating Furnace for Metal Forging & Hot Rolling Processing

The IGBT billet induction reheating furnace is a modern, energy-efficient industrial heating system engineered specifically for precision reheating of solid metal billets before hot rolling, open-die forging, closed-die forging, and hot extrusion processes. Replacing traditional gas-fired furnaces and resistance heating equipment, this induction heating solution delivers stable, repeatable, and environmentally friendly heating performance, becoming the preferred heating equipment for standardized metal processing factories and large steel mills worldwide.

Driven by advanced IGBT medium-frequency solid-state power technology, the steel billet rolling induction heating machine operates based on electromagnetic eddy current heating principles. It generates heat uniformly inside the metal billet from core to surface, realizing integral through-heating instead of conventional surface heating. This core-heating feature effectively eliminates temperature differences between the outer layer and the center of billets, completely solving common industrial problems such as uneven heating, local overheating, severe oxide scale and metal decarburization caused by traditional heating methods. With a power factor up to 0.95 and high thermal conversion efficiency, the equipment greatly reduces redundant energy consumption compared with traditional heating equipment.

This reheating furnace adopts fully automated PLC intelligent control system, matched with automatic feeding, positioning, heating and discharging mechanisms. It supports continuous uninterrupted feeding and 24-hour stable operation, which can be seamlessly connected with automatic rolling mills and forging production lines to realize unmanned assembly line operation. The whole induction billet heating machine is flameless and enclosed, producing extremely thin oxide scale and no open flame pollution. It not only improves workshop operation safety but also meets global industrial environmental protection and low-emission standards, helping enterprises reduce carbon emissions and pass environmental assessment inspections smoothly.
