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.
