摘　　要：对大极板铅电解过程的工艺控制进行了详细阐述,包括大阳极板制作前期杂质含量的控制、铅电解始极片制作工艺的质量要求、大极板铅电解装槽要求、铅电解液的质量要求、铅电解液循环速度及温度的控制,以及铅阳极泥洗水的净化处理。通过上述工艺控制,减少杂质的影响,提高析出铅的产量和质量,降低直流电耗,实现了节能降耗。This paper elaborates on the process control of large-plate lead electrolysis,including impurity control in the early stage of large anode plate preparation,quality requirements for starter sheet preparation process,loading large plates into the cell and the electrolyte,control over the circulation speed and temperature of electrolyte,and purification of anode slime washing water.This process control can reduce the impact of impurities,improve the quality and quantity of precipitated lead,lower DC power consumption and thus achieve energy conservation and consumption reduction.
