Castable for aluminum alloy casting launder as well as preparation method and application of castable
The invention relates to the technical field of refractory materials, and discloses a castable for an aluminum alloy casting launder as well as a preparation method and application of the castable. The castable for the aluminum alloy casting launder comprises a main material and water, the main material comprises the following components in percentage by mass: 45-53% of modified fused quartz with different granularities, 26-32% of ferrochrome slag with different granularities, 2-4% of corundum micro powder, 1-3% of barite micro powder, 1-3% of fluorite micro powder, 2-4% of forsterite micro powder, 2-4% of fly ash, 6-10% of aluminate cement and 1% of a polycarboxylate superplasticizer; and water accounts for 4-6% of the mass of the main material. The surface of the fused quartz is modified, so that the wettability and wrapping property of the fused quartz and powder water slurry can be improved, the material uniformity of the castable during stirring and forming can be improved, and the strength of the castable after curing and drying can be improved.
本发明涉及耐火材料技术领域，公开了一种铝合金熔铸流槽用浇注料及其制备方法与应用；铝合金熔铸流槽用浇注料，包括主料以及水；所述主料包括以下质量百分比的各组分：不同粒度的改性熔融石英45‑53％，不同粒度的铬铁渣26‑32％，刚玉微粉2‑4％，重晶石微粉1‑3％，萤石微粉1‑3％，镁橄榄石微粉2‑4％，粉煤灰2‑4％，铝酸盐水泥6‑10％，聚羧酸减水剂1％；水为主料质量的4‑6％。对熔融石英进行表面改性，可以提高其和粉料水浆体的润湿性和包裹性，有利于提高浇注料搅拌和成型时的物料均匀性，并有利于养护和干燥后浇注料的强度提升。
