Quick-drying high-strength high-refractoriness-under-load castable for blast-furnace tuyere as well as preparation method and application thereof
The invention provides a quick-drying high-strength high-refractoriness-under-load castable for a blast-furnace tuyere. The castable comprises the following raw materials in percentage by mass: 60-72% of particles of at least one of brown aluminum oxide, high-quality alumina and white corundum, 5-10% of silicon carbide, 8-15% of white corundum powder, 5-8% of superfine powder, 0-5% of silicon nitride powder, 0-3% of metal silicon powder, 1-1.5% of steel fiber, 0.5-1% of chrome green, 1.5-2.5% of aluminate cement, 0.1-0.2% of a composite water reducer and 0.03-0.05% of an organic anti-explosion agent. The quick-drying high-strength high-refractoriness-under-load castable product is prepared by uniformly mixing the materials according to the ratio at normal temperature, and packaging. The product, with the nano silica sol as a binding agent, is stirred by a stirrer and poured in a blast-furnace tuyere area, so that residual bricks at the tuyere can be maintained, and integral pouring can also be realized; or prefabricated blocks are manufactured by the product and transported to a site to be directly installed. The product has good construction performance, and can be baked and put into use after short-term maintenance after demoulding. The product has a series of advantages of high refractoriness, high refractoriness under load, high wear resistance, erosion resistance, good thermal shock resistance and the like.
本发明提供一种高炉风口用快干高强高荷软浇注料，由下列原料按质量百分比组成：选自棕刚玉、优质矾土和白刚玉中的至少一种颗粒60～72％、碳化硅5～10％、白刚玉粉8～15％、超微粉5～8％、氮化硅粉0～5％、金属硅粉0～3％、钢纤维1～1.5％、铬绿0.5～1％、铝酸盐水泥1.5～2.5％、复合减水剂0.1～0.2％、有机防爆剂0.03～0.05％。按配比在常温下混匀、包装即得到快干高强高荷软浇注料产品。将该料在高炉风口区域以纳米硅溶胶为结合剂，用搅拌机搅拌、浇注施工，可以维修风口残砖，也可整体浇注。或做成预制块、运至现场直接安装。本产品施工性能良好，脱模后只需短期养护，就可烘烤、投入使用。该产品具有高耐火度、高荷软、高强耐磨、抗侵蚀和抗热震性好等一系列优点。
