Optimization of Plate Thickness Controller
نویسنده
چکیده
The purpose of the hot rolling mill is to make a preheated steel block thinner and longer, see Figure 1. This is done by pulling the plate through two parallel rolls mounted in the rolling mill. Due to the large forces obtained in hot rolling, the elastic de ection of the rolling mill is of the same order of magnitude as the plate thickness. Variations in the rolling force caused by variations in plate hardness and ingoing plate thickness introduces variations in the rolling force and thus plate thickness. The e ect of the force variations are compensated by adjusting the position of the upper roll.
