成功的改进使新精矿的生产提高67%,铜镍高冰镍的产量增加21%。同时实现了尽可能以当地煤作燃料来代替几乎全部靠进口的燃油。这样抵销连续四年通货膨胀的影响才有了能。冶炼厂的改进包括扩大喷淋干燥车间,修改闪速炉加料系统,安装230吨/日的氧气厂和提高渣水碎及渣处理的能力。向闪速炉加精矿的准确的质量流量控制加上使用富氧,即使在较高产景的情况下,也极大地改进了冶金控制和生产效率。选择和研究的这些改造措施,于1980年初成功地投入了生产,并由于新精矿的处理,冶炼厂的潜在能力提高75%。为了减少弃渣的金属损失,需用极少的空气将粉煤喷入闪速炉.此外,还进行了向闪速炉和转炉浸没喷入还原剂和硫化剂的研究工作。
Successful refinements increased the production of new concentrates by 67% and the production of copper-nickel iced nickel increased by 21%. At the same time, it has achieved the goal of using local coal as fuel instead of almost all imported fuel. This offset the impact of four consecutive years of inflation has been able to. Improvements to the smelter include expansion of the spray-drying plant, modification of the flash furnace feed system, installation of a 230-tonne / day oxygen plant and increased capacity for slag and slag treatment. Accurate mass flow control of the flash furnace plus concentrate plus the use of oxygen enrichment have greatly improved metallurgical control and production efficiency, even at higher production levels. These modifications, selected and studied, were successfully put into production in early 1980 and the smelter’s potential capacity has increased by 75% due to the processing of new concentrates. In order to reduce the metal loss of slag, pulverized coal is injected into the flash furnace with a minimum of air, and research into the injection of reducing agent and vulcanizing agent into the flash furnace and the converter is also conducted.
