FORMATION OF REFRACTORY REPAIR MASS

摘要

The present invention relates to a process and a powder mixture for the ceramic welding of electrically cast refractory oxide materials, such as those used in glassmaking and quarrying furnaces, exposed to high heat sources. The powder mixture, which is sprayed in a stream of oxygen gas on a refractory surface to be impregnated, contains combustible particles such as alumina and silicon and refractory oxide particles and at least one scavenger, e.g. between improved refractory material and repair compound. ŕ
