Abstract: The invention relates to a fire resistant substance and to a method for producing a fire-resistant lining. The fire-resistant substance contains MgO sinter and up to 5 wt. % of a reducing agent selected from the group consisting of substances that contain carbon. The lining has several layers with decreasing quantities of reducing agents.

Abstract: The invention concerns a use for a water-containing refractory ceramic cast material based on a hydration-sensitive metal oxide such as MgO and containing carbon, a dispersing agent and a reactive silicic acid for forming a monolithic lining for a metallurgical smelting vessel.

Abstract: 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.

Abstract: The present invention pertains to an electrically conductive, dry, refractory ceramic mass based on a refractory oxidic matrix material containing a source of carbon, such as graphite, carbon black or petroleum coke.
