Abstract
1. Способ алюминотермического получения ферросплавов, включающий смешивание порошков исходных компонентов шихты, содержащей рудный концентрат и алюминий в качестве восстановителя, инициирование процесса горения, механическое отделение полученного литого ферросплава от шлаков, отличающийся тем, что в шихту дополнительно вводят окислитель в количестве не более 15 мас.%, в качестве которого используют перхлорат щелочного металла, а в состав восстановителя вводят не более 15 мас.% магния или сплава алюминия с магнием, в количестве, достаточном для полного восстановления оксидов из рудных концентратов, причем суммарное содержание восстановителя в шихте составляет не более 30 мас.%, размещение шихты в емкость из графита или нитрида бора, инициирование процесса горения на воздухе с помощью вольфрамовой спирали.2. Способ по п.1, отличающийся тем, что в качестве перхлората щелочного металла используют преимущественно перхлорат калия.3. Способ по п.1, отличающийся тем, что в качестве рудного концентрата используют хромитовые обогащенные руды, хромитовые руды бедные по содержанию хрома и железа, ильменитовый концентрат.1. The method of aluminothermic production of ferroalloys, comprising mixing the powders of the initial components of the charge containing ore concentrate and aluminum as a reducing agent, initiating the combustion process, mechanical separation of the obtained cast ferroalloy from slags, characterized in that the oxidizer is additionally introduced in the amount of not more than 15 wt. .%, which is used as alkali metal perchlorate, and not more than 15 wt.% magnesium or an aluminum alloy with magnesium are introduced into the reducing agent in an amount sufficient m for complete reduction of the oxides of the ore concentrate, wherein the total content of reducing agent in the mixture is not more than 30 wt.%, placing the batch in a container made of graphite or boron nitride, initiating combustion in air using a tungsten spirali.2. The method according to claim 1, characterized in that potassium perchlorate is mainly used as alkali metal perchlorate. The method according to claim 1, characterized in that chromite enriched ores are used as ore concentrate, chromite ores are poor in the content of chromium and iron, ilmenite concentrate.
