摘要
在永久不锈钢阴极电解中,生产系统复杂,质量影响因素众多,阴极铜质量成为各冶炼企业竞争的关键所在.主要结合生产管理实践经验,分别探究了阳极铜的元素组成、物理外观、电解液进液方式和循环流量对阴极铜质量的影响.结果表明:采用"刀型"阳极铜和控制阳极铜杂质的最佳成分含量,能够有效减少阳极泥粒子和漂浮阳极泥的产生,提升阴极铜的质量;更改电解液进液方式,并根据生产电流密度合理调节电解液循环流量,也能有效降低阴极铜粒子板率,提升阴极铜的物理外观质量.
Abstract
In permanent stainless steel cathode electrolysis,the production system is complex and there are many factors affecting the quality.The quality of cathode copper has become the key to competition among various smelting enterprises.Based on practical experience in production management,this article explores the effects of the elemental composition,physical appearance,electrolyte inlet method,and circulating flow rate of anode copper on the quality of cathode copper.The results show that adopting a"knife shaped"anode copper and controlling the optimal composition content of anode copper impurities can effectively reduce the production of anode mud particles and floating anode mud,and improve the quality of cathode copper.Changing the electrolyte inlet method and adjusting the electrolyte circulation flow rate according to the production current density can effectively reduce the cathode copper particle plate rate and improve the physical appearance quality of cathode copper.
