Induction hardening

Inductive heating offers the possibility of partially hardening a workpiece. Excellent results can be achieved especially when hardening shaft bearing surfaces. The penetration depth of the hardness zone can additionally be determined via selection of the heating unit working frequency.

What is induction hardening?

Application 1: Hardening of shafts
This illustration shows the hardening procedure on a shaft.

Application 2: Hardening of metal parts
The illustration shows the partial hardening of a band - air-hardening

Application 3: Hardening of slotted holes
Induction hardening of a slotted hole with an elliptical thorn inductor

Application 4: Hardening of shafts in a flow process
Induction hardening of a shaft in a flow process including tempering by means of an induction shower. Tempering is carried out by means of an induction shower immediately after heating, whereby extreme degrees of hardness are attainable. Hardness emulsions can also be used alternatively to water

Application 5: Hardening of strips in a flow process

Induction hardening of a strip in a flow process including tempering by means of an induction shower. Tempering is carried out by means of an induction shower immediately after heating, whereby extreme degrees of hardness are attainable. Hardness emulsions can also be used alternatively to water.
