FIELD: metallurgy.
SUBSTANCE: invention relates to non-ferrous metallurgy field, particularly it concerns to manufacturing of carbon-base materials used for brickwork of bottom of electrolytic cell. Cold-padded baked in the hearth mass contains electro-calcined anthracite, liquid carbonic binding agent, plasticiser and special addition, liquid carbonic binding agent allows following content, wt %: coal-tar asphalt 53.3-61.7, stripping oil 37.8-43.7, antioxidative addition 0.5-3.0. In the capacity of antioxidative addition it is used boron nitride.
EFFECT: there is provided the ability of application at manufacturing of cold-padded baked in the hearth mass for filling of inter-blocked and, particularly peripheral seams in bottom of electrolytic cells and increasing of service durability of carbon bottoms at operation of electrolytic cells.
