A steel ladle bottom concreting material is a bulk fire-resisting material prepared by mixing different granularities of particles, fine powder and micro powder of corundum, fused magnesia-alumina spinel, alpha-activated alumina and magnesia powder according to certain proportion, adding various additives, using aluminate cement as a bonding agent, uniformly stirring and mixing. The steel ladle bottom concreting material comprises the following components in percentage by weight: 10-30% of 25-10 mm corundum, 5-15% of 10-8 mm corundum, 5-15% of 8-5 mm corundum, 5-15% of 5-3 mm corundum, 15-25% of 3-1 mm corundum, 15-25% of 1-0 mm corundum, 5-20% of 0.074-0 mm fused magnesia-alumina spinel, 1-15% of 0.061-0 mm magnesia powder, 5-20% of 0.045-0 mm corundum micro powder or silica micro powder, 2-20% of alpha-activated alumina, 2-15% of calcium aluminate cement, 0.1-1.5% of a water reducing agent and 0.01-1% of an anti-explosion fiber. The steel ladle bottom concreting material is high in fire resistance degree, thermal shock resistance, erosion resistance and physical performance.
