Abstract

Изобретение используется в области металлургии, в частности для выплавки, раскисления, легирования и обработки стали. Способ включает загрузку шихты, подачу под давлением снизу природного газа и воздуха или кислорода с расплавлением шихты газовоздушным или газокислородным факелом. Природный газ и воздух или кислород подают через неводоохлаждаемую газовоздушную или газокислородную форсунку, выполненную в виде концентрически вставленных одна в другую труб, размещенную в отверстии разливочного стакана шиберного затвора ковша-печи с обсыпкой вокруг сухим огнеупорным песком. Природный газ подают по ее наружной трубе, а воздух или кислород - по внутренней. Ковш-печь накрывают крышкой с электродами и дополнительно расплавляют шихту электрическими дугами сверху, и после расплавления скачивают из ковша-печи первичный шлак, подают в него флюсующие реагенты для наводки вторичного шлака и осуществляют продувку инертными газами снизу со шлакообразующими реагентами, совмещая этот процесс с кипением, раскислением, легированием, глубокой десульфурацией, дефосфорацией, гомогенизацией химического состава и температуры готовой стали. Изобретение улучшает качество стали и уменьшает ее себестоимость.
