Composite refractory material for furnace lining of vacuum induction furnace and preparation method of composite refractory material
The invention relates to a composite refractory material for a vacuum induction furnace lining and a preparation method of the composite refractory material. The composite refractory material comprises the following raw materials in parts by weight: 50-80 parts of fused white corundum, 20-45 parts of fused magnesia, 20-25 parts of synthetic magnesia-calcium sand, 15-25 parts of alumina micro powder, 10-15 parts of quartz sand, 5-10 parts of bauxite, 4-8 parts of silicon carbide, 3-7 parts of a binding agent and 0.5-2 parts of an additive. The fused white corundum comprises spherical corundum and tabular corundum, and the mass ratio of the spherical corundum to the tabular corundum is 1: (1-3). The composite refractory material can improve the anti-seismic property and the corrosion resistance of the lining, so that the service life of the lining is prolonged.
本发明涉及一种真空感应炉炉衬用复合耐火材料及其制备方法，包括以下重量份数的原料：电熔白刚玉50～80份，电熔镁砂20～45份，合成镁钙砂20～25份，氧化铝微粉15～25份，石英砂10～15份，铝矾土5～10份，碳化硅4～8份，结合剂3～7份，添加剂0.5～2份；所述所述电熔白刚玉包括球形刚玉、板状刚玉，所述球形刚玉与板状刚玉的质量比为1：(1～3)。该复合耐火材料可以改善内衬的抗震性能和耐腐蚀性能，从而延长内衬的使用寿命。
