摘要
采用转炉处理铜浮渣在能耗指标、产品质量指标以及操作劳动强度方面有了很大的改善,但是该工艺产生的高温烟气和烟尘使得烟气口的寿命只有1~2个月,水冷烟罩的寿命只有3~5个月,严重制约炉子的作业率。针对此问题,某铅冶炼厂通过改进烟口铜水套冷却装置、优化设计水冷烟罩、改进冷却水供水系统等措施,取得了较好的水流量、水路温度、烟气出口温度指标。改进后的铜浮渣:转炉运行平稳,在生产实践运用中烟气冷却能力、抗腐蚀能力及维护简易性都达到优异效果。
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.
