摘　　要：针对现有铅电解阴极机组生产中存在的铅阴极垂直度差、导电棒使用寿命短、接触电阻高、导电棒表面杂质清理困难等问题,基于弹塑性力学、弯曲成形、电阻点焊等理论开发和应用了几种技术,包括刚度增强的板表面压花、阴极板和导电棒的高效分离、导电铜棒的化学清理和阴极片的撕碎处理,并应用于国内一家大型铅冶炼企业新建的48万吨/年项目。实践表明,整体设备生产能力显著提高,生产时间从15秒/片缩短到11.5秒/片,阴极垂直度引起的短路率降低到0.43%。In response to the problems of poor verticality of lead cathodes,short service life of conductive rods,high contact resistance,and difficulty in cleaning impurities on the surface of conductive rods in the production of existing lead electrolysis cathode units,several technologies have been developed and applied based on theories such as elastic-plastic mechanics,bending forming,and resistance spot welding.These technologies include surface embossing with stiffness enhancement,efficient separation of cathode plates and conductive rods,chemical cleaning of conductive copper rods,and shredding of cathode sheets.They have been applied to a newly built 480000 ton/year project of a large lead smelting enterprise in China.Practice has shown that the overall equipment production capacity has significantly improved,with production time reduced from 15 seconds per piece to 11.5 seconds per piece,and the short circuit rate caused by cathode perpendicularity reduced to 0.43%.
