Abstract: The surface roughness rolling-transfer and change law of high strength steel strips and the surface roughness change law of working rolls are studied through a batch of field experiments and analyzed by a statistical method to find out a control method of producing high strength steel strips with especially required roughness. Experimental results show that the surface morphology of high strength steel strips is determined by the end of the continuous rolling mill. A surface roughness prediction model and a rolling-transfer rate model of high strength steel strips and a surface roughness prediction model of working rolls are established in this paper. The rolling-transfer behaviors of high strength steel strips are compared with those of normal strength steel strips. These models can be used to predict the surface roughness of high strength steel strips during industrial production,help to order the cold rolling sequence and make a rolling plan more efficiently,and determine the roll replacing time.
