Optimization and Upgrading of Key Technologies for Lead Electrolysis Equipment Sets

Abstract

In response to the current key issues in the production of existing lead electrolysis equipment, such as poor verticality of lead cathode, inferior welding quality, short service life of conductive rod and high contact resistance, we have developed several technologies based on the principles of elastoplastic mechanics, bending and shaping, resistance spot welding and neural network control.These technologies include the stiffness-enhanced plate surface embossing, the dynamic multi-eigenvalue fusion of BP neural network resistance welding control, and the efficient rod-plate separation for cathode lead plates and conductive rod. They have been applied in a newly constructed 480kt/a project at a large domestic lead smelting enterprise. The results have demonstrated significant improvements in overall equipment production capacity, reducing the production time from 15s/plate to 11.5s/plate, decreasing the short-circuit rate caused by cathode verticality to 0.43%, and extending the service life of conductive rod by 12.8%.
