Abstract

Matters concerned with designing the equipment of and technology for induction thermal treatment of rolling mill rollers. Conditions necessary fo rassuring the thermal treatment quality are formulated: deviations from the required hard nessover the roller body length and over the hardened layer depth shall be kept to a minimum, and there shall be no dangerous thermal and structural stresses able to cause roller fracture either during and after its thermal treatment. Computer models for solving the se problems are developed. A universal approach to computer-aided designing and controlling the thermal operation modes in induction thermal treatment installations is considered. The use of wafer-type inductors with selecting the current frequency for induction quenching is substantiated.
