Abstract
In a modification of the process described in the parent Specification for making alloy steels in a basic open hearth furnace, alloying metals such as chromium, molybdenum, vanadium, titanium, tungsten, copper, or nickel, unless already present in the charge, are added to the slag in combined form, for example as ores, and are reduced from the slag in addition to the manganese present, and pass into the steel bath.
