摘要

铁合金用于改变铁金属和有色金属的成分和性能。因此,铁合金的熔炼量与钢和其他合金的产量相对应。目前世界钢铁产量约为1630亿吨,各种铁合金产量约为4000万吨(2.5%)。各国铁合金生产结构主要不是取决于工业企业的需求,而是取决于矿石储量。过量生产的铁合金出口,而缺少的合金则进口。在俄罗斯,不受原料基础限制的硅合金(44%)产量最大,其次是锰(25%)和铬(23%)铁合金。剩下的铁合金占产量的8%。消费所需的锰铁合金约有一半是在国外购买的,一半是在俄罗斯联邦用外国原料生产的(哈萨克斯坦、南非、加蓬)。俄罗斯联邦完全提供自己的铬铁合金,并销售约80%,其生产主要使用从哈萨克斯坦进口的原材料(约65%)。关键词:铁合金,铬铁,炉渣,铁合金生产

The Waste of the Ferroalloy Production in Russia
Ferroalloys are used to change the composition and properties of ferrous and non- ferrous metals. Therefore, the volume of ferroalloy smelting corresponds to the amount of steel and other alloys produced. Currently world steel production is approximately 1630 million tons, and about 40 million tons of various ferroalloys are produced (2.5%). The structure of ferroalloy production in different countries mainly depends not on the needs of industrial enterprises, but on ore reserves. Excessive amounts of ferroalloys produced are exported, and the missing alloys are imported. In Russia silicon alloys that have no restrictions in the raw material base (44%) are the most produced, then manganese (25%) and chromium (23%) ferroalloys. The remaining ferroalloys account for 8% of production. About half of the manganese ferroalloys needed for consumption are bought abroad, and half are produced in the Russian Federation from foreign raw materials (Kazakhstan, South Africa, Gabon). The Russian Federation provides itself with chromium ferroalloys completely, and sells ∼ 80%, and for their production mainly imported raw materials (∼ 65%) from Kazakhstan are used. Keywords: ferroalloy, ferrochrome, slags, production of ferroalloy
