Abstract：
A large number of defects appeared on the surface of cold-rolled steel sheet in a steel mill,the location of the defect was analyzed and the defect was determined to be caused by the slab crack.In order to reduce the defect rate of slab surface crack,the research object was to reduce the linear defect rate of steel plate surface.ANSYS software was used to establish the solidification model of casting billet,and secondary cooling water distribution analysis was carried out.It is proved that the improvement scheme can reduce the incidence of linear defects on the surface of steel plate and effectively improve the product quality.
