The control methods researches of 1450 hot rolling line roughing shape
The stability of strip threading at the end of finishing process is greatly affected by the shape of roughing intermediate slab in liuzhou iron&steel group co the 1450 hot rolling line,occasional phenomena such as large wedge,broken wedge,tail flick,etc.caused by the bad shape of the incoming plate.Explore the control method of rough rolling strip shape based on the equipment characteristics of rough rolling area,take targeted improvement measures for key equipment,such as equipment rigidity,screwdown system accuracy,alignment,fit clearance,etc,develop and put into use the shape adjustment function to adapt the process parameter optimization,has been applied to practical production and achieved obvious results.
