Repairing material for tapping hole of converter and preparation method of repairing material
The invention relates to a converter tapping hole repairing material and a preparation method thereof. The converter tapping hole repairing material comprises 60-80 parts of fused white corundum, 40-55 parts of fused magnesia particles, 25-35 parts of fused magnesia fine powder, 20-30 parts of synthetic magnesia-calcium sand, 10-25 parts of alumina, 10-15 parts of silicon carbide powder, 8-15 parts of tabular corundum, 5-15 parts of alumina powder, 3-7 parts of phenolic resin and 0.5-2 parts of an additive. The repairing material can be used for repairing the tapping hole, so that an original refractory material of the tapping hole can be continuously used, the refractory material cost is reduced, and the repairing time can be shortened.
本发明涉及一种转炉出钢口修补料及其制备方法，电熔白刚玉60～80份，电熔镁砂颗粒40～55份，电熔镁砂细粉25～35份，合成镁钙砂20～30份，矾土10～25份，碳化硅粉10～15份，板状刚玉8～15份，氧化铝粉5～15份，酚醛树脂3～7份，添加剂0.5～2份。该修补料可以对出钢口进行修复，使得原有出钢口耐火材料能够继续使用，降低耐材成本，并且能够缩短修复时间。
