摘要： PURPOSE:To obtain a refractory powder for thermal spraying which can be easily and inexpensively produced and has excellent corrosion resistance by compounding the respective clinkers of sintered magnesia, electromagnetic magnesia and dolomite of sintered spinel and a refractory material. CONSTITUTION:This powder consists of the refractory material formed by mixing one kind of the sintered magnesia clinker, electromelting magnesia clinker, sintered spinel, dolomite clinker, and lime clinker or the combination thereof and garnet. The above-mentioned powder is formed by ingeniously using the thermal characteristics of the garnet to improve the adhesiveness to the bricks of furnace walls and the compaction of a fused layer. The abnormal expansion of the garnet of the thermal spraying material formed by mixing basic aggregate raw materials and the garnet is initiated by flames at the time of passing the inside of the flame. The specific surface area thereof is then increased and the state having high meltability is attained. Consequently, the aggregate is adhered to the furnace walls having the small specific surface area and the poor adhesiveness.
