Influence of rolling temperature on fatigue life of calibrated rolls
In the hot rolling process calibrated rolls are used for the production of various simple and complex profiles. Rolling temperature is an important parameter of technological process which has great influence on energy costs, scale formation and rolling forces. In order to reduce the cost of energy, an analysis of the rolling temperature influence on fatigue life of the rolls has been carried out.The fatigue life estimation is carried out according to the fatigue life stress concept based on the local stress.Stress spectra in critical areas are determined for three different temperatures. The analysis shows that although lowering of the initial rolling temperature causing decreasing the fatigue life of the roll, the stresses caused by the rolling at thelowest temperature should not lead to roll fracture.
