Abstract

An improvement in the process described in the parent Specification comprises the addition to the steel, before its intermixing with the slag, of a metal such as manganese or chromium which is oxidizable at the expense of iron oxide, and the oxide of which is soluble in the steel. A quantity of silicon may also be introduced into the steel by employing a slag containing a substantial amount of silica.
