Refractory castable for iron runner of blast furnace casting house and preparation method of refractory castable
The invention discloses a refractory castable for an iron runner of a blast furnace casting house and a preparation method of the refractory castable, and the refractory castable for the iron runner of the blast furnace casting house comprises the following components: 45-55 parts of fused brown aluminum oxide; 15 to 25 parts of silicon carbide; 10 to 15 parts of composite micro powder; 2 to 5 parts of Scar71 high-alumina cement; 2-4 parts of metal silicon powder; in addition, high-temperature asphalt powder accounting for 1-3% of the total mass of the raw materials and CarboresP accounting for 0.5-1.5% of the total mass of the raw materials are used as composite carbon sources, so that the problems that in the prior art, carbon in a carbon-containing refractory material is extremely easy to oxidize, the thermal shock resistance and corrosion resistance of the castable are reduced, the castable of the iron runner is peeled off, and the service life of the blast furnace iron runner is shortened are solved.
本发明公开了一种高炉出铁场铁沟用耐火浇注料及其制备方法，所述高炉出铁场铁沟用耐火浇注料，包括以下组分：电熔棕刚玉45‑55份；碳化硅15‑25份；复合微粉10‑15份；Secar71高铝水泥2‑5份；金属硅粉2‑4份；外加上述原料总量质量分数为1‑3％的高温沥青粉和0.5‑1.5％的CarboresP作为复合碳源，解决了现有技术存在的含碳耐火材料中的碳极易被氧化，降低了浇注料的抗热震性和耐腐蚀性，导致出铁沟浇注料剥落并降低高炉出铁沟的使用寿命问题。
