Abstract (en)
A method for coating grain oriented silicon steel to improve its magnetic properties; the method including the steps of preparing a melt of said silicon steel, casting said steel, hot rolling said steel, cold rolling said steel and decarburizing said steel, and being characterised by applying to the surface of said steel a coating of Mg(OH)2 and SiO2 and thereafter final texture annealing said steel in the conventional manner with said coating thereon.
