CCS铜冶炼厂提高阳极板质量的生产实践与探索

Production practice and exploration of improving anode plate quality in CCS copper smelter

针对CCS铜冶炼厂阳极板质量问题,本文进行了分析和总结,将其归纳为化学成分问题和物理规格问题。化学成分方面,影响阳极板质量的主要因素是精炼铜液As含量偏低,部分炉次Fe含量偏高;物理规格方面,影响阳极板质量的主要因素有鼓包、裂纹、耳弯、耳距尺寸、飞边毛刺等。化学成分方面,通过向阳极炉中添加砷铜合金来提高阳极板中As含量,通过增加粗铜氧化程度降低阳极板中Fe含量;物理规格方面,通过加强生产过程管理,控制合理的铜水温度和浇铸速度,改进喷涂系统和冷却水系统等方法来提高阳极板的浇铸质量。采取以上改进措施后,CCS铜冶炼厂有效地提高了CCS阳极板生产质量,降低了废品率和吨铜油耗。

Aiming at the quality problems of anode plates in CCS copper smelters,this article analyzed and summarized them into chemical composition problems and physical specifications problems.In terms of chemical composition,the main factors affecting the quality of the anode plate are the low As content in the refined copper solution and the high Fe content in some furnaces,solution;in terms of physical specifications,the main factors affecting the quality of the anode plate are bulges,cracks,ear bends,ear distance size,flash burrs,etc.Measures to solve the chemical composition problem include adding arsenic-copper alloy to the anode furnace to increase the As content in the anode plate,and increasing the oxidation degree of blister copper to reduce the Fe content in the anode plate;measures taken to solve the problem of physical specifications include strengthening production process management,controlling reasonable copper water temperature and casting speed,improving spraying system and cooling water system,etc.After taking the above improvement measures,the CCS copper smelter effectively improved the production quality of CCS anode plates and reduced the scrap rate and the fuel consumption per ton of copper.
