RH insert tube corundum castable and production method thereof
The invention relates to an RH insert tube corundum castable and a production method thereof, and belongs to the field of refractory materials. The production method comprises the following steps: uniformly mixing the following raw materials in percentage by weight: 58-63% of inked corundum, 25-27% of white corundum, 9-14% of alumina micro powder and 2-4% of calcium aluminate cement, adding water, pouring, drying and demolding to obtain the RH insert tube corundum castable. The RH insert tube corundum castable with the compression strength of 30.9-53.5 Mpa and small linear change range after burning is obtained through scientific compatibility of the inked corundum with the particle size of 8-5 mm, the inked corundum with the particle size of 5-3 mm, the inked corundum with the particle size of 3-1 mm, the white corundum with the particle size of 1-0 mm, the white corundum steel with the particle size of 325 meshes, the aluminum oxide micro powder and the pure calcium aluminate cement, the service life of an insert tube is greatly prolonged, and the RH insert tube corundum castable is suitable for industrial production. The cost of the corundum castable is reduced, the labor intensity of workers is reduced, and good economic benefits and social benefits are achieved.
本发明涉及一种RH插入管刚玉浇注料及其生产方法，属于耐火材料领域。所述生成方法包括：将以下重量百分比的原料混合均匀后：58～63％墨钢玉、25～27％白刚玉、9～14％氧化铝微粉和2～4％铝酸钙水泥，加入水，浇注，干燥，脱模，得RH插入管刚玉浇注料。本发明通过8～5mm粒径的墨钢玉、5～3mm粒径的墨钢玉和3～1mm粒径的墨钢玉、1～0mm粒径的白刚玉、325目的白玉刚、氧化铝微粉和纯铝酸钙水泥的科学配伍，获得了耐压强度为30.9～53.5Mpa，且烧后线变范围小的RH插入管刚玉浇注料，大幅度提高插入管的使用寿命，降低刚玉浇注料的成本，减少职工的劳动强度，具有良好的经济效益和社会效益。
