摘　　要：针对云铜冶炼加工总厂转炉渣返电炉贫化存在的问题,进行了铜转炉吹炼渣还原预处理工业试验。详细阐述了渣中磁性铁的还原率、渣含铜及渣还原前后物相、熔点、粘度的变化,分析了存在的问题,提出了优化思路。In view of the problems existing in recycling converter slag to electric furnace dilution in Yunnan copper smelting plant,the reduction pre-treatment industrial test of copper converting slag was performed.The reduction rate of magnetite in slag,copper contents in slag,and the changes of phase,melting point and viscosity before and after slag reduction were introduced in detail.The problems existing in production were analyzed,and the optimization ideas were put forward.
