摘要
A process for repairing bottom linings of D.C. arc furnaces. A refractory ceramic mass is used for lining the bottoms of D.C. arc furnaces in the area of metallic electrodes placed therein, wherein the refractory ceramic mass comprises one or more refractory oxides, in a grain fraction of less than 8 mm and 10 to 40 wt. % of finely dispersed metallic additives in a grain fraction of less than 0.1 mm, for lining bottoms of D.C. furnaces in the area of metallic electrodes, placed within said bottoms to insure an electrically conductive contact between the refractory ceramic mass and the metallic electrodes.
