ABSTRACT:
A process for producing electromagnetic silicon steel having a cube-on-edge orientation. The process includes the steps of: preparing an aluminum-bearing melt of silicon steel; casting the steel into an ingot; soaking the ingot at an elevated temperature; hot rolling the ingot into a bar of less than 2 inches in thickness; hot rolling the bar into a band of less than 0.2 inch in thickness, when the bar is at a temperature of from 1800 to 1900.degree.F; heat treating the steel; cold rolling the steel at a reduction of at least 75%; decarburizing the steel; and final texture annealing the steel.
