Special high-strength corundum castable and preparation method thereof
The invention discloses a special high-strength corundum castable and a preparation method thereof. The anti-explosion castable is prepared from the following raw materials in parts by weight: 70 to 80 parts of corundum aggregate, 20 to 30 parts of light mullite aggregate, 35 to 45 parts of dolomite powder, 10 to 20 parts of fly ash, 0.05 to 1.5 parts of water reducing agent, 5 to 10 parts of high-alumina cement, 10 to 15 parts of cementing material, 1 to 5 parts of alumina micro powder, 0.5 to 5 parts of stainless steel fiber, 0.05 to 1 part of inorganic fiber and 0.05 to 0.08 part of anti-explosion fiber, the content of bauxite in the corundum aggregate is not lower than 90%, the special high-strength corundum castable further comprises an anti-freezing agent, the content of calcium formate in the anti-freezing agent is not higher than 0.3%, the special high-strength corundum castable is prepared by correspondingly matching and mixing the materials, and the prepared corundum castable has extremely high hardness, extremely good thermal shock stability, good chemical corrosion resistance and better refractoriness, and can be used for preparing the special high-strength corundum castable. The strength and durability of hardened concrete can be improved, burst can be prevented, and the overall service life is prolonged.
本发明公开了一种特种高强刚玉浇注料及其制备方法，由以下重量份的原料制成：刚玉骨料70‑80份、轻质莫来石骨料20‑30份、白云石粉35‑45份、粉煤灰10‑20份、减水剂0.05‑1.5份、高铝水泥5‑10份、胶结料10‑15份、氧化铝微粉1‑5份、不锈钢纤维0.5‑5份、无机纤维0.05‑1份、防爆纤维0.05‑0.08份，所述刚玉骨料的直径均在0.16～1mm之间，刚玉骨料中铝矾土含量不低于90％，还包括防冻剂，防冻剂内甲酸钙的含量不高于0.3％，该特种高强刚玉浇注料，通过上述多个材料进行相应的搭配与混合，所制成的刚玉浇注料，具有极强的硬度、热震稳定性极好、抗化学腐蚀性好，耐火度更好，能提高硬化混凝土的强度和耐久性，能够防止爆裂，提高整体使用寿命。
