Development of improved cube-on-edge texture from strand cast 3pct silicon-iron

Abstract

The degree of cube-on-edge texture attainable by processing of coils hot rolled directly from strand cast slabs tends to be highly variable. Incomplete secondary recrystallization in the product results from excessive grain size in the reheated cast slabs. These large grains fail to recrystallize during subsequent rolling and annealing operations. Prerolling the cast slab about 25 pct produces a smaller grain size in the slab after reheating prior to hot rolling with the result of a uniform and improved texture in the product. The texture changes which take place with and without prerolling are described and analyzed.
