A method of producing cube-on-edge oriented silicon steel strip and sheet from strand cast slabs, wherein a slab is prerolled at a temperature not exceeding 1673 DEG K. with a reduction in thickness up to 50%, and the prerolled slab is reheated to a temperature between 1533 DEG and 1673 DEG K. prior to hot rolling. The slab prerolling temperature, percentage of reduction in prerolling, and the reheat temperature are correlated in accordance with a specific equation in order to control the strain rate during prerolling and to obtain an average grain diameter not exceeding about 9 mm after reheating.
