Induction Heating


What is induction heating?

The induction heating furnace is mainly used for the heating of metal materials before forging, extrusion, hot rolling and shearing. The heating temperature is between 200-1300 degrees. It is the first and only one that can directly heat the workpiece without time-consuming and Expensive conventional heat treatment furnace process furnace.

According to the heating furnace, it can be divided into:

Heating before forging: It is used for heating of gears, ring gears, half shaft connecting rods, bearings, shackles, rigging and other products before forging.

On-line heating: heating of billets, slabs, long steel bars, anti-corrosion spraying of pipes, on-line quenching and tempering of steel (wire) pipes.

Local heating: U-bolt bending, drum hot assembly, steel pipe bending and other production heating.


Induction furnaces are also safer than other furnaces. The induction coil is completely contained within the steel housing and is isolated from the part by a refractory coating. Hot slag or other materials in the furnace will not contaminate the room. The induction coil is also unlikely to come into contact with the workpiece or the operator.

Induction furnaces can improve energy efficiency, reduce operating costs and increase productivity, with a smaller footprint than traditional gas furnaces, and improved product uniformity and quality.
