<p>The invention relates to a process for producing a foamed slag on austenitic stainless melts in an electric arc furnace, wherein a mixture of metal oxides and carbon is introduced into the furnace, underneath the slag and at the metal/slag boundary, the metal oxide is reduced by the carbon and the gases produced bring about the foaming of the slag by the formation of bubbles. Here, the mixture to be charged, which is added in the form of mouldings such as briquettes or pellets, contains not only nickel oxide, iron oxide, iron carriers and carbon but also the required binders.</p> |
