摘　　要：分析了高炉冶炼红土矿生产镍铁合金关键技术。我国成功解决了高炉冶炼红土矿工艺的一系列技术难题,已经可以在600 m3的高炉上冶炼红土矿。用高炉冶炼红土矿生产镍铁合金工艺的单位能耗低于现代高炉炼铁工艺,是多种有价资源综合利用的示范工艺,应该大力推广和发展。Key techniques of ferronickel smelting with laterite ore in blast furnace（BF） were analyzed and a series of technical obstacles had been solved by the Chinese researchers.Up to date,laterite ore can be smelted in 600 m3 BF.Unit energy consumption of this process was less than that of molten BF ironmaking.The technology of laterite ore smelted in BF was a good demonstration of multi-resources utilization with a positive prospect for development and popularization.
