Production method of chromium corundum brick with reduction reaction resistance and thermal shock resistance for non-ferrous metal smelting fuming furnace or side-blown furnace
The invention relates to a production method of chromium corundum bricks with reduction reaction resistance and thermal shock resistance for a non-ferrous metal smelting fuming furnace or a side-blownfurnace. The method includes uniformly mixing the crushed chromium slag, sintered corundum and chromium concentrate; adding into a three-phase electric arc furnace for smelting; smelting to obtain achromium corundum material; crushing, grinding, screening and grading the chromium corundum material to obtain particles with the particle sizes of 5-3mm, 3-1mm and 1-0mm and powder with the particlesizes of 180-mesh and 325-mesh respectively, adding 3-1mm fused zirconium mullite to obtain a mixed premix, adding a binding agent phosphoric acid, uniformly stirring, and standing for more than or equal to 48h; and adding a binding agent aluminum dihydrogen phosphate, mixing, carrying out compression molding, and carrying out high-temperature firing to obtain the chromium corundum brick. The invention has the advantages that the raw material cost is low, the cost performance is high, and the produced chromium corundum brick not only has scouring resistance, erosion resistance and high temperature resistance, but also has reduction reaction resistance and thermal shock resistance, and can be used for furnace slag line parts, bottoms and reaction zones for smelting lead, zinc, tin and othernonferrous metals.
一种抗还原反应、抗热震的有色金属冶炼烟化炉或侧吹炉用铬刚玉砖的生产方法，将破碎后的铬渣、烧结刚玉和铬精矿混合均匀，加入到三相电弧炉中冶炼，进行冶炼得到铬刚玉料，铬刚玉料经破碎、粉磨、筛分分级得到粒度分别为5‑3mm、3‑1mm和1‑0mm的颗粒料以及180目和325目的粉料，并加入3‑1mm的电熔锆莫来石，得到混合预混料，加入结合剂磷酸，搅拌均匀，放置≥48h；加入结合剂磷酸二氢铝，进行混练，压制成型，经高温烧成，得到铬刚玉砖。优点是：原料成本低廉，性价比高，生产的铬刚玉砖不仅具有抗冲刷、抗侵蚀、抗高温性，同时还具有抗还原反应、抗热震性，可用于炼铅、锌、锡等有色金属窑炉渣线部位、底部及反应带。
