Abstract：The passivating process of disc shear in Shougang Jingtang ANDRITZ cross-cut line was analyzed, and the main factors of accelerated passivating process, for example improper blade clearance, unreasonable production scheduling, non-intervention passivating, weak anti-loosing measures and so on were found out.Accordingly, the measures to prolong life of disc shear such as setting proper blade clearance, optimizing production schedule, early intervening passivation, strengthening anti-loosing measures, were put forward.With the help of implementation of the measures, the total shearing tonnage of disc shear increased in each passivation cycle, and the service life of blade prolonged more than 32%.
