Abstract
Process for carrying out the second stage of refining the manufacture of steel in an electric oven, characterized in that it comprises adding the molten steel a mixture of the following ingredients in the indicated proportions: Lime (cao) 40 to 80 parts by weight Iron oxide 5 to 30 parts by weight Oxidizable material 5 to 25 parts by weight The weight of the lime in the mixture being at least twice the weight of the iron oxide, and the weight of the iron oxide in the mixture being insufficient to completely oxidize all the oxidizable material present.
