Abstract Because of special characteristics of process and structure of hot strip temper mill，the work roll wear evolution law is different from that of hot strip mill. However，researches on work roll wear mainly focused on hot strip mill and there was little research on work roll wear evolution law of hot strip temper mill. Accordingly，On the basis of the wear characteristics of hot strip temper mill，a large number of wear data were measured for analyzing the formation and development mechanism of work roll wear. For single-stand four-high hot temper mill，a roll-strip coupling model was established with ABAQUS finite element simulation software and effect of contact pressure on work roll wear evolution rule in different wear stages was obtained. Compared with the actual data of 1 580 mm hot strip mill，the results show that work roll wear evolution law can accurately reflect real wear condition. The conclusion lays the foundation for the development of the wear theory of hot strip temper mill and the further optimization of the wear prediction model.

Key words： hot strip temper mill work roll wear evolution law finite element simulation contact stress
