Claims (2)

1. Способ ведения восстановительной плавки, включающий в себя дозирование рудной части и углеродистых восстановителей, загрузку их в руднотермическую электрическую печь, карботермическое восстановление, выпуск расплава из печи, отличающийся тем, что в период снижения производительности печи, в печь одновременно с ведением восстановительной плавки загружают мелкие фракции продуктов восстановительной плавки размером 0-40 мм, в количестве 0,5-15,0 кг на 1 МВТ активной мощности печи.1. The method of conducting reducing smelting, which includes dosing the ore part and carbonaceous reducing agents, loading them into an ore-thermal electric furnace, carbothermic reduction, and releasing the melt from the furnace, characterized in that, in the period of decreasing furnace productivity, the furnace is simultaneously loaded with reducing melting fine fractions of products of reducing smelting with a size of 0-40 mm, in an amount of 0.5-15.0 kg per 1 MW of active power of the furnace. 2. Способ по п. 1, отличающийся тем, что в качестве продуктов восстановительной плавки используют технический кремний или кремнистые ферросплавы.2. The method according to p. 1, characterized in that technical silicon or silicon ferroalloys are used as reduction melting products.
