The induction hardening process is used to harden a part of the workpiece surface. It is mainly used for hardening shafts, running surfaces or for heating complexly shaped components in a specific area. It can be done manually or automatically.
The penetration depth of the thermal energy results from the choice of the working frequency of the induction heating system. The higher the working frequency, the smaller the penetration depth. Furthermore, different degrees of hardness can be achieved using different cooling media (air, water or special hardness emulsions).
Advantages of induction heating:
• Fast operational readiness
• Treatment time in seconds
• no discoloration (when hardening under protective gas)
• no post-treatment (when hardening under protective gas)
• constant hardness quality
• Problem-free integration into automation processes
• high throughput
