为了挖掘云南冶炼厂现有设备的生产潜力,并解决滇中铜精矿制粒干燥后成球性差、易碎,电炉难以熔炼的问题,由云南冶炼厂、昆明冶金研究所和昆明工学院组成的“三结合”试验小组,在云冶转炉渣降硅、浮选工业试验获得成功的基础上,根据转炉造低硅渣后,炉温升高,增大了“吃”冷料能力的情况,并鉴于铜精矿含铜高(25％±)、含
In order to tap the potential of the existing equipment in Yunnan smelter and to solve the problems of poor balling, fragility and difficult smelting in EAF after pelletizing and drying of copper concentrate in Yunnan, it is composed of Yunnan Smelter, Kunming Institute of Metallurgy and Kunming Institute of Technology Of the “triple combination” test group, based on the success of the industrial trial of silicon reduction and flotation of Yun Ye converter slag, the furnace temperature increased and the ability of “eating” cold feed increased , And in view of copper concentrate copper high (25% ±), containing
