Production application of cross measurement and adjustment of roller system
Under long-term high load production conditions of hot rolling mills,the defects caused by insufficient control of mill memorial archway window and roll seat precision are gradually enlarged,occasional loss of control of plate shape due to roller system crossing,the typical feature is to use changing rollers as a sign of appearance or elimination.This article describes and analyzes the phenomenon of roll system crossing in liuzhou iron &steel group co the 1450 hot rolling line,The laser tracker is used to measure the rolling mill memorial archway window combi-nation with the measured data to adjust the memorial archway lining plate size and roll seat lining plate size for re-duce the cross angle of roll system axis,further improve abnormal phenomena such as rolling mill axial shifting,plate shape,rolling force difference,enhance the stability of rolling mill equipment and plate shape.
