Method for producing a grain-oriented electrical steel by an oxygen-blown convertor

摘要

A method for producing steel for grain-oriented electrical steel sheet or strip in an oxygen-blown convertor, which comprises preliminarily adjusting the manganese content of molten pig iron to be charged into the convertor to not more than 0.35%, and blowing the thus adjusted molten pig iron in the convertor to obtain molten steel containing not more than 0.065% Mn, not less than 0.03% C and not more than 1000 ppm (O).
