Abstract
A simple method of producing a rim-stabilized steel ingot without requiring the use of special equipment wherein a rimming-type steel is teemed into an ingot mold and thereafter allowed to rim for a suitable period of time, and then adding a particulate mixture of aluminum and an exothermic material to the top of the molten metal so that the exothermic mixture will ignite, melting and superheating the aluminum content which is driven into the molten steel at the ingot core.
