- Abstract
The experimental method for physical modeling of operating conditions of a continuous billet casting machine (CCM) rolls is developed to estimation the temperature field and especially the temperature at the surface of the roll by measuring the temperature with the thermocouples (fully embedded) at multiple point inside the roll. The physical model allows for the automated recording of the quasi-stationary temperature field in the rolls surface layers and at various distances from its working surface. The main mechanisms of impact failure in the service exposed CCM roll material are investigated at the maximum temperature of the thermal cycle.
