摘 要：Employing Simulated Annealing Algorithm （SAA） and many measured data, a calculation model of work roll wear was built in the 2 800mm 4-high mill of Wuhan Iron and Steel （Group） Co.（WlSCO）. The model was a semi-theory practical formula. Its pattern and magnitude were still hardly defined with classical optimization methods. But the problem could be resolved by SAA. It was pretty high precision to predict the values for the wear profiles of work roll in a rolling unit. After one-year application, the results show that the model is feasible in engineering, and it can be applied to predict the wear profiles of work roll in other mills
