Anti-erosion iron runner castable for large blast furnace
The invention relates to an anti-erosion iron runner castable for a large blast furnace. The material comprises, according to weight percentage, 58-64 parts of compact brown fused alumina particles, 2-5 parts of white corundum particles, 16-23 parts of silicon carbide, 5-7 parts of aluminum oxide micro-powder, 2-3 parts of pure calcium aluminate cement, 2-3 parts of silicon dioxide micro-powder, 1.5-2.5 parts of spherical asphalt particles, 0.5-1.2 parts of carbon black powder, 1.5-3.5 parts of metal silicon powder, 0.2-0.6 part of boron carbide, 0.1-0.2 part of metal aluminum powder, 0.15-0.2part of a water reducing agent, 0.6-1 part of an anti-erosion agent and 0.05-0.08 part of explosion-proof fibers. According to the castable, the service life of a primary runner of a main runner is prolonged, and the stability of safe operation of an iron runner is improved. It is verified that the requirements for rapid baking without cracking, erosion resistance, oxidation resistance, slag adhesion resistance and iron flux can be met, the iron flux can reach 180000 tons or above without repairing, and good application prospects are achieved.
本发明涉及一种大高炉抗侵蚀铁沟浇注料，按照重量百分比，包括致密棕刚玉颗粒58～64份、白刚玉颗粒2～5份、碳化硅16～23份、三氧化二铝微粉5～7份、纯铝酸钙水泥2～3份、二氧化硅微粉2～3份、球状沥青颗粒1.5～2.5份、炭黑粉0.5～1.2份、金属硅粉1.5～3.5份、碳化硼0.2～0.6份、金属铝粉0.1～0.2份、减水剂0.15～0.2份、抗侵蚀剂0.6～1份、防爆纤维0.05～0.08份，本发明所提供的浇注料延长主沟一代沟役的使用寿命，提高铁沟安全运行的稳定性。经验证，能达到快速烘烤不开裂、抗冲刷侵蚀、抗氧化、抗沾渣以及通铁量的要求，不经修补通铁量达18万吨以上，具有良好的应用前景。
