In the non-ferrous metal smelting industry, the recycling of scrap copper is of great significance for resource conservation and environmental protection. Rotary anode furnaces play a key role in this process and are essential core equipment in the scrap copper refining process.
Scrap copper comes from a wide range of sources, has a complex composition, and contains numerous impurities. The unique design and functionality of rotary anode furnaces efficiently refine sorted scrap copper directly into anode copper liquid that meets specific requirements. The furnace's 360-degree rotation ensures thorough mixing of the materials within the furnace and their contact with added fluxes, oxidants, and other agents, accelerating chemical reactions and more rapidly separating impurities from the copper.
During the refining process, rotary anode furnaces precisely control furnace temperature, atmosphere, and other parameters to selectively oxidize and remove impurities from the copper liquid. For example, by gradually introducing oxygen into the furnace, impurities such as iron and zinc are preferentially oxidized, resulting in the formation of slag, which is then discharged, effectively improving the copper's purity. Furthermore, the rotating furnace ensures uniform heating of the copper liquid, preventing localized overheating or overcooling, ensuring a stable refining process and consistent product quality. The anode copper liquid refined in the rotary anode furnace has significantly reduced impurity content, meeting the requirements for subsequent casting into anode copper plates. As the raw material for electrolytic refining, the quality of anode copper plates directly affects the purity and quality of the final electrolytic copper. The efficient refining of the rotary anode furnace lays a solid foundation for the production of high-purity electrolytic copper and improves the efficiency and profitability of the entire copper recycling industry chain.
In short, the rotary anode furnace, with its outstanding performance, plays a key role in the refining of raw copper and promotes the sustainable recycling of copper resources.
