The application of converters in the treatment of copper dross is an emerging technology application, and its energy consumption indicators, product quality indicators and operating labor intensity havegreatly improved. However, the high-temperature flue gas and fume dust produced by the process make the lifetime of the flue gas outlet 1~2 months and the lifetime of the water-cooled hood 3~5 months, which severely restricts the operating rate of the furnace.To solve this problem, a lead smelter has achieved good water flow, water temperature and flue gas outlet temperature indicators by improving the copper water jacket cooling device at the flue, optimizing the design of water-cooled flue gas cover and improving the cooling water supply system. The improved copper slag converter runs smoothly, and achieves excellent results in the production practice of flue gas cooling capacity, corrosion resistance and maintenance simplicity.
