摘要： There is practiced a method of making low carbon silicon steel in which the lining of the ladle is made of dolomite instead of fireclay or alumina, and there is added to the ladle, before the metal is teemed into it, a pre-melted or pre-fused mixture containing appropriate portions of calcium silicate, lime, magnesia, and spar, and argon bubbling is practice as before but preferably for a slightly longer period of time, and the ladle is provided during argon bubbling with a hood or lid. There is then obtained a product steel with desirably low contents of oxygen and nitrogen, and without penalty in the form of higher contents of aluminum and titanium in the finished steel.
