Stationary roll

Our computer controlled hardening furnaces have been developed in house and are unique in the world. The roll remains at its position, whilst the heating and quenching units are moving.

 


Hardening

The specific set up of our hardening and quenching units enables a very short time interval between the austenising and quenching stages. This leads to the highest possible hardness levels. Also, our unique combination of austenisting time and temperature is the key to optimum microstructure for superior roll performance.

 


Total Barrel Hardening (TBH)

Our classic hardening process enables a smooth transition between the state of compression in the outer , hardened layer and a state of tension in the inner part of the roll. It also guarantees a low level of retained austenite and the presence of a high amount of carbides in the microstructure. The computer controlled process enables reproducibility and homogeneity.

 


Induction hardening

Our heat treatment capabilities are extended by progressive induction hardening . We can harden each neck section to a specific hardness level and can adjust the depth of hardness through frequency adjustment. Progressive induction hardening is specifically used when hardening smaller size rolls and for rolls of the secondary hardening family.
