Description

Изобретение относитс  к области металлургии .This invention relates to the field of metallurgy.

Известен сиособ получени  ферросилици  в руднотермических электронечах путем восстановлени  кремни  из кварцита, углеродом кокса в присутствии железа. В качестве железосодержащего компонента шихты используют стальную стружку и мелкий лом.There is a known method for producing ferrosilicon in ore-thermal electrons by reducing silica from quartzite with coke carbon in the presence of iron. Steel chips and small scrap are used as the iron-containing component of the charge.

Однако такой способ характеризуетс  высоким содержанием хрома 0,4-0,6% в ферросилиции , нереход щего полностью в сплав из стружки -и лома, и соответственно в специальных чугунах, выплавл емЕзГх с использованием ферросилици .However, this method is characterized by a high chromium content of 0.4–0.6% in ferrosilicon, which does not completely melt into chips and scrap, and, accordingly, in special cast irons, is smelted using Ferrosilicon.

С целью снижени  содержани  хрома до 0,2% и повыи1ени  фосфора по 0,15% по предлагаемому способу в качестве железосодержащего компонента ввод т нелегированную чугунную стружку в соотношении 3 : 1 со стальной. При этом по вл етс  возможность увеличени  вторичного напр жени  наIn order to reduce the chromium content to 0.2% and increase phosphorus at 0.15%, according to the proposed method, unalloyed iron chips in the ratio of 3: 1 with steel are introduced as an iron-containing component. In this case, it is possible to increase the secondary voltage

5-6%:5-6%:

Использование изобретени  повышает производительность руднотермической печн на , снижает расход электроэнергии на 4-4,5%, уменьшает содержание хрома в ферросилниии в 1.5--2 раза до величины 0,2- 0,3%.The use of the invention improves the productivity of the ore-smelting furnace, reduces energy consumption by 4–4.5%, reduces the chromium content in ferrosilium by 1.5–2 times to a value of 0.2–0.3%.
