Steel ladle repairing material produced by using recycled waste corundum nozzle seating brick material and method for repairing steel ladle lining by using the same
The invention discloses a steel ladle repairing material produced by utilizing a recycled waste corundum nozzle seating brick material and a method for repairing a steel ladle lining. The repairing material is prepared from 84% of the waste corundum brick material (comprising 15% of a granular material with the particle size of 6-3 mm, 25% of a granular material with the particle size of 3-1 mm, 35% of a granular material with the particle size of 1-0 mm and 9% of 200-mesh powder), 5% of spinel powder, 2% of fused magnesium powder, 4% of activated aluminum oxide micro powder and 5% of 71 cement. All the raw materials are evenly mixed in a mixing mill, discharged, packaged in bags and stored in a damp-proof mode. When the steel ladle repairing material is in use, when a steel ladle is off line and needs to be repaired, a proper amount of the steel ladle repairing material is weighed according to the repairing area, water accounting for 4-5% of the total weight of the material is added, and the materials are stirred uniformly in a stirrer for standby application; residual steel slag, attachments and dust on the inner wall of the steel ladle are cleaned up; a to-be-repaired place is smeared with the repairing material until the to-be-repaired place is flat; smearing is performed for the second time after ten minutes; and then the to-be-repaired place is naturally aired for 8 hours and then normally baked.
本发明公开了一种利用回收废刚玉座砖料生产的钢包修补料及其修补钢包内衬的方法，该修补料采用废刚玉砖料84%（粒径6‑3mm的颗粒料15%，粒径3‑1mm的颗粒料25%，粒径1‑0mm的颗粒料35%，200目粉料9%），尖晶石粉5%，电熔镁粉2%，活性氧化铝微粉4%，71水泥5%配制而成，将所有原料在混炼机中混合均匀，放料进行分袋包装，防潮存放。使用时，在钢包下线需要进行修补时，依据修补的面积，称取适量的钢包修补料，并添加物料总重4‑5%的水在搅拌机中搅拌均匀备用；将钢包内壁的残余钢渣、附着物和灰尘清理干净；用修补料在待修补的地方涂抹至平整；十分钟后进行第二次涂抹；然后自然晾至8小时后进行正常烘烤。
