Abstract：Ｃross breaks are formed on the surface of cold rolled and tempered strip during temper rolling, which influence the surface quality and mechanical characteristics of the temper rolled strip. By analyzing the loading of strip at S rolls and formation mechanism and influencing factors of cross breaks, it was concluded that the main cause of cross breaks is the yield point elongation and the high tensile stress at the entrance of temper rolling mill.It is necessary to establish rational elongation and tension,control the quality of coming strip strictly,to avoid cross breaks, improve the surface quality of strip.
