Abstract
1. Способ повышения степени восстановления металлических компонентов в хромитовом концентрате при выплавке ферросплава, подходящего для изготовления нержавеющей стали, отличающийся тем, что хромитовый концентрат подают совместно с никельсодержащим сырьевым материалом, так что посредством подаваемого количества никельсодержащего сырьевого материала достигают требуемой степени восстановления металлических компонентов ферросплава.2. Способ по п.1, отличающийся тем, что никельсодержащий сырьевой материал подают в количестве 5-25 масс.%, предпочтительно 10-20 масс.% от общего количества материала, подаваемого в плавильную печь.3. Способ по п.1 или 2, отличающийся тем, что во время плавки восстанавливается по меньшей мере 2,6% хрома, содержащегося в хромитовом концентрате.4. Способ по п.1, отличающийся тем, что во время плавки восстанавливается по меньшей мере 37,4% железа, содержащегося в хромитовом концентрате.5. Способ по п.1, отличающийся тем, что по меньшей мере одну часть никельсодержащего сырьевого материала подают в составе гранул, получаемых из хромитового концентрата.6. Способ по п.1, отличающийся тем, что по меньшей мере одну часть никельсодержащего сырьевого материала предварительно обрабатывают отдельно от гранул хромового концентрата перед подачей в плавильную печь.7. Способ по п.1, отличающийся тем, что в плавильную печь подают в качестве никельсодержащего сырьевого материала, по меньшей мере частично, оксид никеля.8. Способ по п.1, отличающийся тем, что в плавильную печь подают в качестве никельсодержащего сырьевого материала, по меньшей мере частично, никелевую руду и/или никелевый концентрат.9. Способ по п.1, �1. A method of increasing the recovery of metal components in a chromite concentrate during the smelting of a ferroalloy suitable for the manufacture of stainless steel, characterized in that the chromite concentrate is supplied together with a nickel-containing raw material, so that the required degree of reduction of the metal components of the ferroalloy is achieved by the supplied amount of nickel-containing raw material. 2. The method according to claim 1, characterized in that the nickel-containing raw material is fed in an amount of 5-25 wt.%, Preferably 10-20 wt.% Of the total amount of material fed to the smelter. The method according to claim 1 or 2, characterized in that at least 2.6% of the chromium contained in the chromite concentrate is recovered during smelting. The method according to claim 1, characterized in that at least 37.4% of the iron contained in the chromite concentrate is recovered during smelting. The method according to claim 1, characterized in that at least one part of the Nickel-containing raw material is supplied as part of granules obtained from chromite concentrate. The method according to claim 1, characterized in that at least one part of the nickel-containing raw material is pre-treated separately from the chrome concentrate granules before being fed to the melting furnace. The method according to claim 1, characterized in that nickel oxide is supplied, at least in part, to nickel oxide as a nickel-containing raw material. The method according to claim 1, characterized in that the nickel ore and / or nickel concentrate is fed, at least in part, to the smelting furnace as a nickel-containing raw material. The method according to claim 1, �
