Filling material for gaps between coke oven wall bricks and steel plates and preparation method of filling material
The invention belongs to the field of refractory materials for repairing coke ovens in the iron and steel industry, and particularly relates to a filling material for gaps between coke oven wall bricks and steel plates and a preparation method of the filling material. The filler comprises the following raw material components in percentage by weight: 16%-30% of fused quartz, 10%-35% of calcined quartz, 10%-15% of aluminum powder, 7%-20% of iron powder, 5%-20% of FeO, 5%-15% of ZnO, 1%-5% of CrN, 2%-8% of active alpha-Al2O3 and 0.1%-0.3% of a water reducing agent. The filling material can be combined with furnace wall refractory bricks and steel plates in a bidirectional melting mode, the combination strength is high, and the material hanging time is long.
本发明属于钢铁行业焦炉修补用耐火材料领域，具体的说涉及一种用于焦炉炉墙砖和钢板空隙的填充料及其制备方法。按重量百分比计，所述填充料原料组分包括：熔融石英：16％～30％、煅烧石英：10％～35％、铝粉：10％～15％、铁粉：7％～20％、FeO：5％～20％、ZnO：5％～15％、CrN：1％～5％、活性α‑Al2O3：2％～8％、减水剂：0.1％～0.3％。本发明填充料可与炉墙耐火砖、钢板实现双向熔融结合，结合强度高，挂料时间长。
