Abstract
A process for regenerating steel scrap by melting and refining it, the improvement wherein carbon is added to molten scrap steel melt in an amount sufficient to adjust the carbon content of the melt to 0.6 to 3.0%, and the scrap steel is refined by blowing oxygen therein. This method can also be applied to the production of steel from reduced iron.
