During hot rolling, steel is deformed at roll bite at temperature ranging typically from 850 to 1150 °C. Under severe cyclic mechanical and thermal loads and in presence of abrasive scale, wear of rolls is inevitable. The paper reviews adverse effect of roll wear on performance of the HSM. Factors responsible for higher wear rate of rolls have ...
