Our innovative Shaft Forging Induction Heating System offers unmatched performance and efficiency, making it the ideal choice for manufacturers.
Custom induction heating solutions for solid, hollow, stepped and long shafts before forging, with fast heating, precise temperature control and easy automation integration.
The LJinduction shaft forging induction heating system is designed for shaft parts that require fast, uniform and controllable heating before hot or warm forging.
Designed for shaft forging, not general-purpose heating
Suitable for solid, hollow, stepped and long shafts
Fast and repeatable heating performance
Uniform temperature from surface to core
Lower scale loss than fuel-fired furnaces
Custom coil and automation solutions available
A shaft forging induction heating system is a specialized pre-forging heating solution for solid, hollow, stepped and long shafts, using electromagnetic induction to deliver fast, accurate and repeatable heating before forging.
How it works
Alternating current flows through the induction coil and creates a magnetic field. This field induces eddy currents inside the shaft, generating heat directly in the workpiece for faster and more controllable heating than traditional furnaces.
Suitable forging processes
Shaft hot forging
Warm forging
End heating
Section heating
Scan heating
Single-shot heating
Why induction is ideal for shafts
Long shafts and shafts with complex geometry require better control of heating uniformity, cycle time and local temperature distribution. Induction heating makes it easier to control both local and overall heating, especially for long, stepped or high-value shaft parts.
The Shaft Forging Induction Heating System is designed to provide precise control, ensuring optimal heating for various shaft types.
Utilizing the Shaft Forging Induction Heating System, manufacturers can enhance their production lines with advanced technology.
