Description
Summary:Three articles will describe three stages in the development of an automatic control system for the surface roughness of rolled strip: (1) analysis of the formation of surface roughness; (2) its mathematical description; (3) development of a control algorithm. In the first part, we consider the basic factors that determine strip roughness. An approach to developing a mathematical model of the surface-roughness formation on cold-rolled strip is proposed. A model is developed for 08Ю steel rolled on the 2030 mill in the cold-rolling shop at PAO NLMK. The results given by the model are compared with the measured surface roughness.
