ABSTRACT "Pasty gasket for producing a leakproof seal between surfaces which are subjected to heat and which have to be joined" The pasty gasket (5) is placed in particular on the upper edge (6) of a metallurgical container (1) in order to produce a leakproof seal with the cover (4) of the latter. The gasket (5) is constituted by a mixture con- taining from 0.5 to 20 % by weight of plasticizing sub- stances containing in particular clay and/or bentonite, 80 to 99.5 % by weight of organic particles such as paper and/or inorganic particles such as carbon, carbide, borides, nitrides, silicides and sulfides, alone or in combination, and/or anhydrous and/or hydrated refractory oxides such as silica, alumina, chromium-magnesium oxide, magnesium oxide, chamotte and mixtures thereof, the whole being given a pasty form by approximately 20 to 30 % by weight of water relative to the weight of the dry constituents, the mixture of these constituents being produced shortly before application of the gasket. Use in order to produce a leakproof seal between the casting ladles, casting distributors and covers thereof, converters and their smoke- and dust-removing hoods and all surfaces which are subjected to heat and which have to be joined. See Figure 1.
