In this paper, roll wear calculation model is developed considered the length of rolled strip, load distribution between rolls, roll surface roughness and other factors, and the corresponding calculation procedure has been developed. The experimental results show that the calculation value of the program is close to the actual data, and its accuracy can meet the requirement of on-line shape control. Based on the procedure, wear of each roll is calculated to study the effects of asymmetric bending. It is shown that asymmetric bending can decrease the local severe wear of rolls, and improve the uniform degree of roll wear distribution, thus the effects of asymmetric bending force on intermediate roll is better than that on work roll. Therefore asymmetric bending of intermediate roll can be used to reduce the wear of rolls in production.
