摘要
A process for producing electromagnetic silicon steel having a cube-on- edge orientation. The process includes the steps of: preparing a melt of silicon steel containing from 0.02 to 0.06% carbon, from 0.0006 to 0. 0080% boron, up to 0.0100% nitrogen and from 2.5 to 4% silicon; casting the steel; hot rolling the steel; cold rolling the steel to a thickness no greater than 0.020 inch; heat treating the steel at a temperature between 1550° and 2000° F. in a hydrogen-bearing atmosphere; removing at least 0.02 micron of surface from each side of the steel; heat treating the steel at a temperature between 1300° and 1550. degree. F. in a hydrogen-bearing atmosphere; applying a refractory oxide coating to the steel and final texture annealing the steel.
