High-thermal-conductivity molten iron trough castable
The invention discloses a high-thermal-conductivity molten iron trough castable, which is prepared from the following raw materials in parts by weight: fused brown fused alumina, fused compact corundum, special-grade bauxite, silicon carbide, pure calcium aluminate cement, silica powder, bimodal activated alumina powder, spherical asphalt, nano carbon black powder, carbon resin powder, a carbon dispersing agent, an antioxidant, organic fibers, an explosion-proof agent and a high-efficiency water reducing agent. Aiming at the problem of poor heat-conducting property of the traditional castable,the proportion of each basic raw material is scientifically adjusted, the nano carbon black powder, the carbon resin powder and the spherical asphalt are introduced for reasonable grading, and the carbon dispersing agent and the composite antioxidant are used as auxiliary materials, so that the heat conductivity of the molten iron trough castable is greatly improved; meanwhile, the finished high-thermal-conductivity molten iron trough castable has good oxidation resistance, high-temperature strength, volume stability and scouring resistance; the service life of the molten iron trough can be greatly prolonged in cooperation with a cooling device, and economic benefits and environmental protection benefits of blast furnace ironmaking are improved.
本发明公开了一种高导热铁水沟浇注料，是由原料电熔棕刚玉、电熔致密刚玉、特级铝矾土、碳化硅、纯铝酸钙水泥、硅微粉、双峰活性氧化铝微粉、球状沥青、纳米碳黑粉、碳树脂粉、碳分散剂、抗氧化剂、有机纤维、防爆剂和高效减水剂按一定重量份配制而成；本发明针对传统浇注料导热性能差的问题，科学调整了各基础原料的配比，引入了纳米碳黑粉、碳树脂粉与球状沥青合理级配，辅以碳分散剂和复合抗氧化剂，大大提高了铁水沟浇注料的导热性；同时成品高导热铁水沟浇注料具有很好的抗氧化性能、高温强度、体积稳定性和抗冲刷性能，配合冷却装置，可大大提高铁水沟的使用寿命，提高了高炉炼铁的经济效益和环保效益。
