Non‐linear optimal control for the hot‐steel rolling mill
网页2019年9月26日The aim of the hot strip finishing mill process is to roll transfer bars, produced in a rough milling process (around 30 mm thick), into steel strips of variable thickness (between 0.8 and 20 mm) [ [4], [5] ]. The reduction of the thickness is achieved by moving the metal strips through rolling strands where pressure is exerted [ [6] [8] ].
