Abstract
A physicomathematical model is proposed for the thermal stress of steel rollers quenched after inductive heating. The model involves numerical solution of a system of interrelated nonlinear heat-conduction and thermoviscoelasticity equations. It takes account of the kinetics of austenite decomposition and the specifics of inductive heating. The validity of the model is confirmed by comparing the calculated stress in a roller (diameter 210 mm) with experimental data obtained by the Saks method.
