Ladle wall castable and preparation method thereof
The invention relates to the technical field of refractory materials, in particular to a ladle wall castable which comprises the following raw materials in parts by weight: 21-24 parts of corundum slag particles with the particle size of 5-8mm; 13-16 parts of corundum slag particles with the particle size of 3-5 mm; 10-14 parts of corundum slag particles with the particle size of 1-3 mm; 10-14 parts of corundum slag particles with the particle size of 0.2-1 mm; 2-4 parts of air-quenched blast furnace slag aggregate with a particle size of 1-3 mm; 2-4 parts of air-quenched blast furnace slag aggregate with the particle size of 0.2-1 mm; 5-8 parts of corundum slag powder with the particle size of less than 0.074 mm; 15-20 parts of bauxite powder with the particle size of less than 0.074 mm; 5-8 parts of active aluminum oxide micro powder with the particle size of less than 0.048 mm; 1-3 parts of silica powder with the particle size of less than 0.074 mm; 1-3 parts of CA-50 calcium aluminate cement with the particle size of less than 0.088 mm; 0.1-0.3 part of sodium hexametaphosphate with the particle size of less than 0.074 mm; and 0.05 to 0.08 part of explosion-proof fiber. The invention also provides a preparation method of the ladle wall castable. The preparation method comprises the following steps: adding the raw materials into a stirrer according to the weight ratio, uniformly mixing and packaging.
本发明涉及耐火材料技术领域，尤其是涉及一种包壁浇注料，包壁浇注料的原料按重量份数包括以下组分：粒径为5‑8mm的刚玉渣颗粒21‑24份；粒径为3‑5mm的刚玉渣颗粒13‑16份；粒径为1‑3mm的刚玉渣颗粒10‑14份；粒径为0.2‑1mm的刚玉渣颗粒10‑14份；粒径为1‑3mm的风淬高炉渣骨料2‑4份；粒径为0.2‑1mm的风淬高炉渣骨料2‑4份；粒径为＜0.074mm的刚玉渣粉料5‑8份；粒径为＜0.074mm的铝矾土粉15‑20份；粒径为＜0.048mm的活性三氧化二铝微粉5‑8份；粒径为＜0.074mm的硅微粉1‑3份；粒径为＜0.088mm的CA‑50铝酸钙水泥1‑3份；粒径为＜0.074mm的六偏磷酸钠0.1‑0.3份；防爆纤维0.05‑0.08份。本发明还提供一种包壁浇注料的制备方法：先将原料按重量比加入搅拌机中，混合均匀包装。
