Изобретение относитс к области черной металлургии и может примен тьс дл получени ферросилици с низким содержанием примесей.The invention relates to the field of ferrous metallurgy and can be used to produce ferrosilicon with a low content of impurities.
Известные способы рафинировани ферросилици путем обработки расплава карбонатами кальци и магни не обеспечивают достаточно полное (более ) удаление алюмини и вызывают технологически неизбежное загр знение ферросилици восстановленным кальцием и магнием. .The known methods of refining ferrosilicon by treating the melt with calcium and magnesium carbonates do not provide sufficiently complete (more) removal of aluminum and cause technologically unavoidable contamination of ferrosilicon with reduced calcium and magnesium. .
По лредлагаемому способу рафинирование ферросилици проводитс карбонатом железа, вводимым на струю расплава в количестве от 5 до 10% от его веса.According to the proposed method, the refining of ferrosilicon is carried out by iron carbonate introduced into the jet of melt in an amount of from 5 to 10% of its weight.
В качестве .рафинировочного материала, содержащего карбонат железа, например, можетAs a refining material containing iron carbonate, for example, it can
быть использован бакальский сидерит в .виде кусков размером от 20 до 60 мм.Bakal siderite can be used in the form of pieces from 20 to 60 mm in size.
Рафинирование ферросилици карбонатом железа позвол ет понизить содержание алюмини и кальци более чем на 50%.Refining ferrosilicon with iron carbonate reduces the aluminum and calcium content by more than 50%.
Предмет изобретени Subject invention
Способ рафинировани ферросилици путем обработки расплава карбонатами, отличающийс тем, что, с целью более полного удалени алюмини и кальци , расплав обрабатывают карбонатом железа, вводимым на струю ферросилици в количестве 5-10% от веса расплава в виде кусков размером 20- 60 мм.The method of refining ferrosilicon by treating the melt with carbonates, characterized in that, in order to completely remove aluminum and calcium, the melt is treated with iron carbonate introduced into the jet of ferrosilicon in an amount of 5-10% by weight of the melt in the form of pieces of 20-60 mm.
