The surface defects affecting the quality of hotrolled strips are various in appearance and complicated in mechanism, which involve many technological links such as the metallurgical composition control, slab quality and hot rolling. In order to solve the problems of nonstandard implementation, inconsistent quality criteria, missed detection and wrong judgment, and customer demand during the surface judgment, from the research of hotrolled surface atlas formulation, the key technology of defect detection of the surface inspection instrument, the design of surface defect grade system and the design of surface automatic judgment product grade system, how to realize the intelligent automatic judgment of surface quality was discussed. At the same time, the intelligent automatic judgment process was realized in the related system, and the accuracy rate of most defect judgment reached 90%.
