SKS炼铅法协同处理硫酸铅渣工业试验

Industrial Test of Synergistic Treatment of Lead Sulfate Slag by SKS Lead Smelting Process

通过研究硫酸铅渣的成分、性质、反应特征和开展协同处理过程的热平衡计算,结合工业试验,得到了硫酸铅渣配入比例在15%条件下的无烟块煤配入比例、渣型控制、氧料比控制等关键工艺参数条件,探索出了SKS炼铅法协同处理硫酸铅渣的最佳冶炼条件,以期进一步提高底吹炉处理硫酸铅渣的能力。

By studying the composition, properties and reaction characteristics of lead sulfate slag, heat balance calculation of synergistic treatment process was carried out.Combined with industrial experiments, the key process parameters such as proportion of anthracite lump coal, slag type control, and oxygen material ratio control were obtained when the proportion of lead sulfate slag was 15%.The optimum smelting conditions of SKS lead smelting process for synergistic treatment of lead sulfate slag were explored, so as to further improve the capacity of bottom blowing furnace to treat lead sulfate slag.
