ABSTRACT:
Steel powders are added to steel in a stream of inert gas introduced into the ladle above the casting mold, at a point near the exit of the steel from the ladle. The powders are thus entrained in the metal entering the mold and dissolve therein. The lance that injects the powders may also plug the ladle outlet. The powders can be used not only to perform their cooling function but also to introduce alloying elements.
