Abstract
1. Способ утилизации промышленных дисперсных ферросплавов, включающий их рассев с отделением мелкой фракции 0-10 мм, подвергаемой в дальнейшем брикетированию, посредством дозирования мелкой фракции ферросплавов и связующего вещества, их перемешивания, прессования и сушки брикетов, отличающийся тем, что в состав материала дополнительно вводят материал-адсорбент, обладающий низкой плотностью, развитой поверхностью и высокой поглощающей способностью по отношению к раствору связки или растворителю, в количестве 2-20% от массы шихты. ! 2. Способ по п.1, отличающийся тем, что в качестве материала-адсорбента используют вермикулит. ! 3. Способ по любому из пп.1 и 2, отличающийся тем, что для облегчения растворения брикетов при введении в сталь вводят флюоритовый концентрат в количестве 0-7% от массы шихты. ! 4. Способ по п.1, отличающийся тем, что для уменьшения взаимодействия растворителя с отсевами ферросплавов в состав шихты вводится пассиватор в виде калиевого хромпика (бихромата калия) в количестве 0-0,2% от массы порошка ферросплава.1. A method of utilization of industrial dispersed ferroalloys, including their screening with the separation of a fine fraction of 0-10 mm, which is subjected to further briquetting, by metering a fine fraction of ferroalloys and a binder, mixing them, pressing and drying briquettes, characterized in that the material contains additional the adsorbent material is introduced having a low density, a developed surface and a high absorbing capacity in relation to a binder solution or solvent, in an amount of 2-20% of the charge weight. ! 2. The method according to claim 1, characterized in that vermiculite is used as the adsorbent material. ! 3. The method according to any one of claims 1 and 2, characterized in that to facilitate the dissolution of the briquettes when introduced into the steel, a fluorite concentrate is introduced in an amount of 0-7% by weight of the charge. ! 4. The method according to claim 1, characterized in that to reduce the interaction of the solvent with the ferroalloy screenings, a passivator in the form of a potassium chromium peak (potassium dichromate) in an amount of 0-0.2% by weight of the ferroalloy powder is introduced into the charge composition.
