Impermeable and anti-erosion molten pool castable for aluminum smelting furnace
The invention discloses an anti-permeation and anti-erosion molten pool castable for an aluminum smelting furnace. The refractory castable is prepared from the following raw materials in parts by weight: 50-70 parts of fused mullite particles, 5-15 parts of tabular corundum particles, 1-10 parts of tabular corundum fine powder, 1-10 parts of silicon carbide fine powder, 3-12 parts of alpha-type calcined activated aluminum oxide, 1-8 parts of rho-type calcined aluminum oxide, 1-5 parts of kyanite, 2-8 parts of pure calcium aluminate cement, 1-6 parts of barium sulfate precipitate, 0.3-5 parts of industrial barium carbonate and 0.01-0.5 part of a water reducing agent. According to the anti-permeation and anti-erosion aluminum smelting furnace molten pool castable, the raw materials are compounded to play a synergistic role, so that the anti-permeation and anti-erosion aluminum smelting furnace molten pool castable has excellent capability of resisting corrosion of metal aluminum molten liquid, and has strong anti-permeation and anti-erosion capabilities on molten slag formed in smelting; the preparation method is simple, raw materials are easy to obtain, and production cost is low.
本发明公开了一种抗渗透防侵蚀铝熔炼炉熔池浇注料，由以下重量份数的原料组成：电熔莫来石颗粒50‑70份、板状刚玉颗粒5‑15份、板状刚玉细粉1‑10份、碳化硅细粉1‑10份、α型煅烧活性氧化铝3‑12份、ρ型煅烧氧化铝1‑8份、蓝晶石1‑5份、纯铝酸钙水泥2‑8份、硫酸钡沉淀1‑6份、工业碳酸钡0.3‑5份、减水剂0.01‑0.5份。该抗渗透防侵蚀铝熔炼炉熔池浇注料通过原料复配发挥协同作用，具有优良的抵抗金属铝熔液侵蚀的能力，而且对在冶炼中形成的熔渣的防渗透和抗侵蚀能力强；且制备方法简单，原料易得，生产成本低。
