Abstract

Раскрыты способ получения ферросплава, такого как сталь, в металлургической печи и восстановительный загружаемый материал для применения в способе. Способ включает применение углеводородного полимера в качестве части восстановительного загружаемого материала и подбор соотношения добавки углеводородного полимера и добавки другого восстановителя для оптимизации производственных показателей способа. Восстановительный загружаемый материал включает (i) углеводородный полимер и (ii) другой восстановитель.Disclosed are a method for producing a ferroalloy such as steel in a metallurgical furnace and a reducing feed material for use in the method. The method includes the use of a hydrocarbon polymer as part of the reducing feed material and the selection of the ratio of the addition of the hydrocarbon polymer and the addition of another reducing agent to optimize the performance of the method. The reducing feed material includes (i) a hydrocarbon polymer and (ii) another reducing agent.
