Abstract:The lead electrolytic refining process is a crucial component of current pyrometallurgical lead smelting. This study focuses on the energy-saving and cost-reducing renovation practices in Electrolytic Lead Workshop E. By upgrading key equipment such as electrolytic cells, rectifiers, and anode vertical mold units, Workshop E has achieved significant technological and economic improvements. Post-renovation, the workshop not only enhanced production efficiency and safety but also reduced failure rates and safety risks, while markedly decreasing energy consumption of natural gas and electricity. Five months of operational data indicate that Workshop E's electrolytic lead output is stable and exceeds the designed capacity, with an average production rate of 107.36%. The consumption of natural gas and electricity has significantly decreased, saving the company approximately 3.89 million yuan annually in production costs, including 1.28 million yuan in natural gas, 0.68 million yuan in electricity, and 1.93 million yuan in labor costs. Additionally, the renovation has increased automation levels and optimized the working environment, further enhancing economic benefits. The transformation of Workshop E not only advances lead smelting technology but also delivers substantial economic returns, offering valuable insights for the sustainable development of the electrolytic lead production industry.
