High-performance mullite castable and preparation method thereof
The invention belongs to the technical field of refractory materials, and particularly relates to a high-performance mullite castable and a preparation method thereof. The high-performance mullite castable comprises the following raw material components in percentage by weight: 65-75% of electrically fused mullite aggregate, 10-20% of white corundum powder, 1-8% of zirconium silicon micropowder, 2-10% of calcined alumina powder, 1-5% of electrically fused pure calcium aluminate cement, 2-5% of kyanite powder, 2-5% of sillimanite powder, and 1-6% of zirconite powder. The total weight percentage of the raw materials of the high-performance mullite castable is 100%, and nano calcium carbonate accounting for 0.1-1% of the total weight of the raw materials and a polycarboxylate superplasticizer accounting for 0.1-0.5% of the total weight of the raw materials are added to the high-performance mullite castable. The castable disclosed by the invention has high refractoriness and thermal shock resistance, the high-temperature wear resistance is greatly improved, the high-temperature performance and the use performance of a traditional castable are improved, and the problem that the castable is easy to peel off in the use process is solved.
本发明属于耐火材料技术领域，具体涉及一种高性能莫来石浇注料及其制作方法。涉及的高性能莫来石浇注料的原料组分及重量百分比为：电熔莫来石骨料65‑75%、白刚玉粉10‑20%、锆硅微粉1‑8%、煅烧氧化铝粉2‑10%、电熔纯铝酸钙水泥1‑5%、蓝晶石粉2‑5%、硅线石粉2‑5%；锆英石粉1‑6%；高性能莫来石浇注料的原料重量百分比总和为100%，高性能莫来石浇注料还外加有占原料总重量0.1‑1%的纳米碳酸钙和占原料总重量0.1‑0.5%的聚羧酸减水剂。本发明的浇注料同时具备高耐火度和热震稳定性且高温耐磨性能大幅提高，改善了传统浇注料的高温性能和使用性能，解决了浇注料使用过程中易剥落的问题。
