Mechanisms for Enhancing Strip Flatness in Temper Mill and their Application

Abstract:

Abstract. In order to enhancing strip flatness in temper mill, in this paper, stress state, micro structure characteristics of contact surface, energy characteristics, dislocation intensity were analyzed. Plastic deformation characteristics of metal during tempering process have been come to a conclusion. Two mechanisms, friction mechanism and elongation rate mechanism, are proposed for enhancing strip flatness during tempering process. On the basis of these mechanisms, strip flatness control strategies suitable for tempering of ordinary cold rolled products, cold rolled deep-draw products, hot rolled products and hot rolled high strength steel products are discussed, and proper equipment configuration is proposed.
