<p>The invention relates to a process for producing foamed slag. The problem addressed by the invention is that of providing a process or material which can be used to foam a slag with a high chromium oxide content. This is carried out by virtue of the fact that a mixture of metal oxides and carbon is introduced into an electric arc furnace, underneath the slag, at the metal-slag boundary, the metal oxide is reduced by carbon and limestone becomes thermally dissonant, and the gases produced bring about foaming of the slag by the formation of bubbles.</p> |
