Research on the gap setting model of short stroke control system in hot edge rolling

According to the phenomenon of width losing in slab end, the spread of slab end including edger pressing, dog bone spread and nature spread, short stroke control was used in 2300 hot strip roughing mill. The parabola model has been proposed in this article, because of the disadvantage of broken line used by 2300 hot strip mill, and the online implementation plan of parabola model has been given. The broken line model and the parabola model have been contrasted by simulation, which indicates that the control effect of parabola model is better than the broken line model.
