High-temperature-resistant iron runner castable and preparation method thereof
The invention relates to a high-temperature-resistant iron runner castable and a preparation method thereof. The high-temperature-resistant iron runner castable is prepared from the following components in parts by weight: 20 to 25 parts of high bauxite clinker, 35 to 40 parts of brown aluminum oxide, 22 to 25 parts of silicon carbide, 2 to 5 parts of carbon material, 2 to 3 parts of binding agent, 8 to 8.8 parts of ultrafine powder, 0.1 to 0.4 part of composite anti-explosion agent, 2 to 4 parts of antioxidant and 0.15 to 0.2 part of DF-401 water reducing agent. The composite anti-explosion agent comprises organic fibers and superfine metal aluminum powder, and the mass ratio of the organic fibers to the superfine metal aluminum powder is (1-2):(1-3). The antioxidant is metal silicon powder and boron carbide powder, and the mass ratio of the metal silicon powder to the boron carbide powder is (1-2):(1-3). Through the structural design of the high-temperature-resistant iron runner castable, the technical problem that an existing Al2O3-SiC-C iron runner castable in the prior art cannot meet the large-scale development requirement of a blast furnace smelting technology is solved.
本发明涉及一种耐高温铁沟浇注料及其制备方法；按照重量份数计，包括高铝矾土熟料20份‑25份、棕刚玉35份‑40份、碳化硅22份‑25份、碳素材料2份‑5份、结合剂2份‑3份、超细粉8份‑8.8份、复合防爆剂0.1份‑0.4份、抗氧化剂2‑4份和DF‑401减水剂0.15份‑0.2份；所述复合防爆剂为有机纤维和超细金属铝粉，有机纤维和超细金属铝粉的质量比为(1‑2):(1‑3)；抗氧化剂为金属硅粉和碳化硼粉，金属硅粉和碳化硼粉的质量比为(1‑2):(1‑3)；通过耐高温铁沟浇注料的结构设计以解决现有技术中存在的现有的Al2O3‑SiC‑C铁沟浇注料无法满足高炉冶炼技术向大型化发展要求的技术问题。
