Abstract
In the manufacture of steel having an accurately determined carbon content, molten pig iron or raw iron is refined to form a molten steel bath having a lower carbon content than the intended final carbon content of the steel, whereafter the steel bath is carburized by dissolving therein iron carbide in quantities such as to obtain the desired final carbon content.
