Anti-stripping swing chute castable containing mullite, kyanite and composite antioxidant and preparation method of anti-stripping swing chute castable
The invention discloses an anti-stripping swing chute castable containing mullite, kyanite and a composite antioxidant and a preparation method of the anti-stripping swing chute castable. The refractory material is mainly prepared from the following raw materials in percentage by mass: 0 to 10 percent of corundum, 30 to 45 percent of high-aluminum clinker, 20 to 35 percent of mullite, 8 to 15 percent of silicon carbide, 5 to 10 percent of kyanite, 3 to 6 percent of active Al2O3 micro powder, 2 to 4 percent of silicon micro powder, 1.5 to 2.5 percent of composite antioxidant, 3 to 5 percent of pure calcium aluminate cement and 1.5 to 2.5 percent of asphalt. In addition, explosion-proof fibers accounting for 0.03-0.15% of the total weight of the raw materials and a water reducing agent accounting for 0.05-0.15% of the total weight of the raw materials are added. By adopting the anti-stripping swing chute castable prepared by the preparation method disclosed by the invention, the thermal shock resistance, the anti-stripping capability, the erosion resistance, the scouring resistance and the wear resistance of the Al2O3-SiC-C swing chute castable are improved; and the service life of the iron runner material is prolonged by more than 30%.
本发明公开了一种含莫来石、蓝晶石、复合抗氧化剂的抗剥落摆动溜槽浇注料及其制备方法。以质量百分含量表示，主要由原料刚玉0～10％、高铝熟料30～45％、莫来石20～35％、碳化硅8～15％、蓝晶石5～10％、活性Al2O3微粉3～6％、硅微粉2～4％、复合抗氧化剂1.5～2.5％、纯铝酸钙水泥3～5％和沥青1.5～2.5％组成；另外，加入占各种原料总重量0.03～0.15％的防爆纤维和占各种原料总重量0.05～0.15％的减水剂。采用本发明制备的抗剥落摆动溜槽浇注料，提高了Al2O3‑SiC‑C摆动溜槽浇注料的抗热震性能、抗剥落能力、抗侵蚀性能、耐冲刷性能及耐磨性能；延长了铁沟料的使用寿命，延长达到30％以上。
