Использование: область металлургии, в частности при переплаве отходов постоянных магнитов. Цель: повышение коэффициентов элементов основы железа, никеля, кобальта и меди. Сущность: в способе, включающем загрузку кусковой шихты в индукционную печь, нагрев, расплавление и выдержку, согласно изобретению шихту подвергают дополнительному нагреву плазменной или электрической дугой до температур 1873-2373 К, а время выдержки расплава в данном интервале температур составляет 1-10 мин на каждую массовую долю в процентах алюминия в отходах. При использовании при переплаве окисленных отходов их подшихтовывают к кусковым в количестве 5 - 95% или к кусковым и окисленным отходам в количестве 10 - 90%. Положительный эффект: экономия шихтовых материалов.Usage: the field of metallurgy, in particular in the remelting of waste permanent magnets. Purpose: increasing the coefficients of the elements of the base of iron, nickel, cobalt and copper. Essence: in a method comprising loading a lump charge into an induction furnace, heating, melting and holding, according to the invention, the mixture is subjected to additional heating by a plasma or electric arc to temperatures of 1873-2373 K, and the melt holding time in this temperature range is 1-10 minutes per each mass fraction in percent of aluminum in the waste. When using oxidized waste during remelting, it is blended to lump in the amount of 5 - 95% or to lump and oxidized waste in the amount of 10 - 90%. Positive effect: saving charge materials.
