摘要

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%.
