摘要： Apparatus and method for continuously casting metal strip includes a pair of casting rolls having casting surfaces with a center portion, edge portions each having average surface roughness between 3 and 7 Ra, and intermediate portion between each edge portion and the center portion, the center portion average surface roughness between 1.2 and 4.0 times the edge portion surface roughness, and the intermediate portions average surface roughness between that of the edge and center portions. The surface roughness of the center portion is tapered across its width, and may be tapered across its width is in stepped zones. The center portion may have surface roughness varied across the surface to correspond to a desired variation in metal shell thickness across the cast strip. The center portion may be at least 60% of the casting roll width, and each edge portion may be up to 7% of the casting roll width.
