Abstract
A process for producing silicon steel having a cube-on-edge orientation and a permeability of at least 1850 (G/Oe) at 10 oersteds, which includes the steps of: cold rolling silicon steel annealing the cold rolled steel prior to a final cold roll, at a temperature of from 1400 DEG to 1700 DEG F for a period of from 15 seconds to 2 hours cooling the annealed steel at a rate substantially equivalent to a still air cool and cold rolling the cooled steel at a reduction of at least 80 percent.
