Blast furnace stemming added with silicon-titanium-iron nitride composite material and preparation method of blast furnace stemming
The invention belongs to the technical field of refractory materials for blast furnace ironmaking, and particularly relates to blast furnace stemming added with a silicon-titanium-iron nitride composite material and a preparation method of the blast furnace stemming. The blast furnace stemming is composed of a dry mixture and a liquid binding agent, wherein the dry mixture comprises 5-25 parts by mass of a silicon-titanium-iron nitride composite material. The using amount of the liquid binding agent is reduced by 4-15% compared with the using amount of the liquid binding agent when Si3N4-Fe is adopted, the production and manufacturing cost is saved, meanwhile, the generation amount of air holes in the stemming in the high-temperature using process is reduced, and the strength and erosion resistance of the stemming can be effectively improved.
本发明属于高炉炼铁用耐材技术领域，尤其是一种添加氮化硅钛铁复合材料的高炉炮泥及其制备方法。本发明高炉炮泥由干混合料和液态结合剂组成，干混合料包括5～25质量份的氮化硅钛铁复合材料。本发明液态结合剂用量较采用Si3N4‑Fe时液态结合剂的用量降低了4～15％，节约了生产制造成本，同时还减少了高温使用过程中炮泥中气孔的产生量，可有效提高炮泥的强度和抗侵蚀性。
