一种RH浸渍管热态喷补料及其使用方法
摘要：
一种RH浸渍管热态喷补料及其使用方法，该喷补料主要组分的重量百分数为：刚玉66～80％，镁铝尖晶石3～10％，氧化铝微粉4～8％，铝镁金属复合粉12～20％。使用时，以氧气或氧气与空气的混合气体为载体及助燃气体，将配制好的喷补料输送至喷枪，喷补在要修补的RH浸渍管浇注料本体部位，修补区域的炉温≥800℃。本发明提供的喷补料使用过程中不加水，不含低熔点结合剂，材料回弹率低，粘结强度高，得到的修补层在使用中具有优异的耐高温性能，具有抗钢水、钢炉渣侵蚀和冲刷的性能，可延长RH浸渍管寿命。
摘要（英）：

The invention discloses a hot-spray-mending material of an RH dip pipe and a using method of the hot-spray-mending material. The hot-spray-mending material comprises the following main components in percentage by weight: 66-80% of corundum, 3-10% of magnesium aluminate spinel, 4-8% of alumina micropowder and 12-20% of aluminum-magnesium metal composite powder. When the hot-spray-mending material is used, oxygen or a mixed gas of oxygen and air serves as a carrier and a combustion-supporting gas, and the prepared spray-mending material is delivered to a spray gun and is sprayed and mended on an RH dip pipe castable body part to be mended, wherein the furnace temperature of a mending region is higher than or equal to 800 DEG C. The spray-mending material disclosed by the invention is free of adding water in the using process, free of low-melting-point binding agents, low in rebound rate and high in bonding strength; and the obtained mending layer has excellent high temperature resistance in use and has the performances of molten steel resistance, steel furnace slag resistance and scouring resistance, and the service life of the RH dip pipe can be prolonged.
