Abstract��After putting converter steel into practice, the capacity for rolling region of special steel plant has been greatly released, so production specifications of the small workshop have been extended from 12��35 mm to 12��55mm. And at the same time, a new defect of end shear crack during shearing process will appear, affecting the physical quality of manufactured products. Start from the formation of crack and optimize the cooling bed and shear process system, measures to effectively prevent the emergence of a shear cracks were put forward and the excellent quality of steel was promoted.
