介绍了在闪速熔炼过程中 ,铜在电炉渣中的损失状况。结合生产实践 ,介绍了控制电炉渣含铜低于 0 .8%的几点措施 :采用新型精矿喷嘴 ,稳定闪速炉炉浆 ;向闪速炉中添加焦粉 ;控制炉渣的铁硅比 ;增加铜液澄清时间 ;向电炉中加入还原剂煤块或黄铁矿等。
The loss of copper in the electric furnace slag during the flash melting process is introduced. In combination with the production practice, the measures to control the copper content in the electric furnace slag below 0.8% are introduced: the new type concentrate nozzle is used to stabilize the flash furnace slurry; the coke powder is added to the flash furnace; the iron-silicon ratio ; Increase the time to clarify the copper liquid; to join the reductant coal furnace or pyrite and so on.
