cold rolling mill heating

Induction heating in vario rolling mills SMS Elotherm GmbH

Induction heating in cold rolling mills . For cold rolling of thin strips, the strip geometries and the material properties must be kept within close tolerances. The precise control capability of induction heating makes it particularly significant for thin strips. Along with full heating with boosters, partial heating is used in cold rolling mills.
