Abstract

The study presents the results of industrial trials of the smelting technology of low-carbon ferrochrome from substandard chrome ores of the Sopcheozerskoye deposit. The alloys were smelted in the industrial furnace DSP-bI (6.5 MBA) using several methods: directly from chrome concentrate, as well as by refining the ore-lime melt in order to reduce the iron content. As a result, low-carbon ferrochrome of various grades was obtained, meeting the requirements of GOST 4757-91 (ISO 5448-81). Replacement of ferrosilicochrome with ferrosilicon improved the technological parameters of the smelting process: chromium recovery increased by 9% and power consumption decreased by 11%.

用不合格铬矿石生产高质量铬铁的工业试验

介绍了从索普切尔斯科耶矿床不合格铬矿中冶炼低碳铬铁的工业试验结果。这些合金在DSP-bI （6.5 MBA）工业炉中采用几种方法进行熔炼：直接从铬精矿中熔炼，以及通过精炼矿石灰熔体以降低铁含量。从而获得各种等级的低碳铬铁，满足GOST 4757-91 （ISO 5448-81）的要求。用硅铁代替硅铁铬改善了冶炼工艺参数，铬回收率提高9%，电耗降低11%。
