The invention provides a corundum self-flowing castable. The corundum self-flowing castable is prepared from the following raw materials in parts by weight: 40-60 parts of fused white corundum aggregate, 30-50 parts of fused white corundum fine powder, 12-20 parts of Portland cement, 5-12 parts of slaked lime, 20-30 parts of alumina micro powder, 1-3 parts of a water reducing agent, 6-9 parts of carbon black, 12-16 parts of melamine and 1-3 parts of a binding agent. The corundum self-flowing castable has good adjustable flowability and good compression strength, it is guaranteed that the castable can be poured without a vibrator during pouring, gaps generated during pouring are reduced, the service life of a casted body is prolonged, the casting is not influenced by a construction environment and can be carried out in a narrow space, the practicality is good, the work strength for operators is reduced, and the reliability is good.
本发明提出了一种刚玉自流浇注料，由以下原料按重量份制备而成：电熔白刚玉骨料40‑60份、电熔白刚玉细粉30‑50份、硅酸盐水泥12‑20份、熟石灰5‑12份、氧化铝微粉20‑30份、减水剂1‑3份、炭黑6‑9份、三聚氰胺12‑16份和结合剂1‑3份。本发明刚玉自流浇注料具有良好的流动性和流动性可调节，良好的耐压强度，保证了浇注料在浇注时不需振动器就可以进行浇注，减少了浇注时产生的缝隙，提高了浇注体的使用寿命，不受施工环境的影响，在狭小的空间内也可以进行浇注，实用性能好，降低了作业人员的工作强度，可靠性能好。
