ABSTRACT:
A process for producing silicon steel strip of less than 0.30 mm thickness having cube-on-edge orientation, which comprises heating a silicon steel slab to 1300.degree.-1400.degree. C., hot rolling to hot band thickness, removing hot mill scale, cold rolling to intermediate thickness without annealing the hot rolled band, subjecting the intermediate thickness cold rolled material to an intermediate anneal at a temperature of 1010.degree. to about 1100.degree. C. with a total time of heating and soaking of less than about 180 seconds, cold rolling to a final thickness of less than 0.30 mm, decarburizing, applying an annealing separator, and finally annealing in conventional manner.
