<p>A process for producing a foamed slag on austenitic stainless melts in an electric arc furnace. A mixture of metal oxides and carbon is introduced into the furnace, the metal oxide is reduced by the carbon below the slag at the metal/slag interface, and the resulting gases bring about the foaming of the slag by bubble formation. The mixture to be charged, which is added in the form of preforms such as briquets or pellets, contains iron oxide, iron carriers, carbon and the required binders in addition to nickel oxide.</p> |
