Abstract

PURPOSE: In surface hardening of rolls by induction hest, provision of a surface hardening process by induction heat wherein the internal and external temperature distribution at the surfaces of a heating material is made flat, quenching crack by quencying after the heating is prevented and setting of hardening temperature is made easy.
