Hot strip mill consists in reheating furnace, roughing mill, finishing mill, laminar cooling bed and coiling station. The mechanical properties are determined by the temperature control accuracy during heating, rolling and cooling of hot-rolled materials in hot rolling process. In order to obtain high quality of the dimension and the shape of hot coils, the deformation of hot-rolled materials and dynamic control of the rolling mill must be evaluated. In this paper, we introduced the three dimensional deformation analysis for hot-rolled materials during a roughing process, shearing simulation to eliminate the bar crop by shearing machine. And we suggested the three dimensional multi-bodies dynamics finite element model to clarify the vibration mechanism of four high hot rolling mills. It can fast and accurately the entire system of actual mills.
