一、前言在有色冶金中采用电炉熔炼处理銅和銅-鎳矿石,还是近三十来年的事情。由于这一方法日益显示出其特有的优越性,目前在苏联、芬兰、挪威和瑞典等国家已被广泛采用,在我国也受到了一定的重視。但由于它毕竟是个新的冶炼方法,国內外关于电炉熔炼的理論研究都还很不完善。特别是关于电炉直接处理粉状物料的报道更少。为了推进这方面的研究工作,本文拟以我厂电炉炼鋼生产实践为基础,对粉矿电炉熔炼的合理作业制度提出初步看法,供作討論。二、粉矿电炉熔炼实践我厂系采用六电极矩形电炉熔炼銅精矿成冰銅。 First, the preface In the non-ferrous metallurgy using electric smelting copper and copper - nickel ore, or nearly thirty years of things. As this method shows its unique superiority day by day, it has been widely adopted in the countries such as the Soviet Union, Finland, Norway and Sweden, and it has also received some attention in our country. However, since it is a new method of smelting after all, the theoretical researches on electric furnace smelting at home and abroad are still not perfect. In particular, there are fewer reports on the direct treatment of powdered materials by electric furnaces. In order to promote this research work, this paper intends to use my EAF steelmaking practice as a foundation, put forward a preliminary view of the reasonable operation system of smelting EAF for discussion. Second, the practice of smelting furnace EAF Our factory uses a six-electrode rectangular furnace smelting copper concentrate into copper.
