LOWER THAN THE NORMAL TEMPERATURE OF CASTING, POURIG THE STEEL INTO A CRUCIBLE HEATED BY INDUCTION AND POURING THE ADDITIONS OF ALUMINUM AND OTHER DEOXIDIZING AGENTS, AND THE CONSTITUENT ELEMENTS OF A SLAG CAPABLE OF FIXING THE ALUMINA, THE CAPACITY OF THE CRUCIBLE BEING UTILIZED AS A RESERVE TO PERMIT THE CASTING OF STEEL WITHOUT INTERRUPTION WHEN THE FEEDING IS INTERRUPTED FOR CHANGING THE LADLE, THE MATERIALS CONTAINED IN THE CRUCIBLE BEING SUBJECTED TO GYRATORY MOVEMENTS BY ELECTRIC INDUCTION, SO THAT THE INCLUSIONS OF ALUMINA AND OTHERS RESULTIG FROM THE KILLING ARE FIXED BY THE SAID SLAG, AND EVACUATING THE STEEL IN A CONTINUOUS MANNER PROTECTED FROM THE AIR.
