Abstract

Способ выплавки рафинированного феррохрома, включающий загрузку кремнистого восстановителя, рудно-известковой части шихты и оксида бора, наведение шлака, восстановительную плавку и выпуск продуктов плавки, отличающийся тем, что оксид бора вводят в печь в шлаковый расплав за 10-20 мин до выпуска продуктов плавки в количестве 0,20-0,30% от массы шлакового расплава. A method of smelting refined ferrochrome, including loading a siliceous reducing agent, an ore-calcareous part of a charge and boron oxide, slag induction, reduction smelting and release of melting products, characterized in that boron oxide is introduced into the furnace into the slag melt 10-20 minutes before the release of melting products in the amount of 0.20-0.30% by weight of the slag melt.
