Abstract
Способ десульфурации чугуна, выплавленного в индукционной печи с кислой футеровкой, включающий расплавление металлошихты, скачивание шлака и последующую десульфурацию порошковой магнийсодержащей проволокой, отличающийся тем, что расплав после скачивания шлака подвергают термовременной обработке по режиму: нагрев до 1500-1520°С, изотермическая выдержка 10-15 мин, естественное охлаждение с печью до температуры выпуска, далее скачивают шлак и переливают металл в ковш, при этом вводят на струю раскислитель FeSi 65 класса крупности 1, 2.The method of desulfurization of pig iron smelted in an induction furnace with an acid lining, including melting a metal charge, downloading slag and subsequent desulfurization with a flux-cored magnesium-containing wire, characterized in that the melt after downloading the slag is subjected to thermal treatment according to the regime: heating to 1500-1520 ° C, isothermal exposure 10 -15 min, natural cooling with the furnace to the discharge temperature, then slag is downloaded and the metal is poured into the ladle, while FeSi 65 deoxidant of particle size 1, 2 is introduced onto the jet.
