Изобретение относится к области черной металлургии, в частности к производству ферросплавов. Способ позволяет увеличить степень извлечения металла из шлака с получением металла, обладающего дефосфорирующими свойствами, без снижения содержания в нем кремния и при пониженном содержании в нем углерода и фосфора. Переплав шлака производят в рафинировочной печи с полным проплавлением заданной шихты в присутствии извести при их соотношении 1 : (0,4 - 0,6), при этом загрузку извести на плавку после выпуска расплава осуществляют к бортам печи, а шлака - в центр печи к электродам.The invention relates to the field of ferrous metallurgy, in particular to the production of ferroalloys. The method allows to increase the degree of extraction of metal from slag to obtain a metal with dephosphorizing properties, without reducing the content of silicon in it and with a reduced content of carbon and phosphorus. Slag is remelted in a refining furnace with full penetration of a given mixture in the presence of lime at a ratio of 1: (0.4 - 0.6). electrodes.
