Использование: в области черной металлургии при производстве стали в печи, стенки которой, хотя бы частично, футерованы огнеупорами, а именно в кислородном конвертере и электродуговой печи, перерабатывающих металлошихту. Изобретение может использоваться для производства стали из одной только твердой железосодержащей шихты или когда расплавленный железосодержащий металл загружается как часть железосодержащего материала. Твердая металлошихта может состоять из различных видов железосодержащих материалов, таких, как стальной скрап, чугун, губчатое железо в форме окатышей, кусков, брикетов и т.д. Сущность изобретения: способ производства стали включает загрузку в футерованную печь шлакообразующих и железосодержащих материалов, подачу кислорода, расплавление железосодержащих материалов, перегрев расплава до температуры выпуска и последующий выпуск. Вначале загружают часть шлакообразующих материалов, на них углеродсодержащие материалы с низким содержанием летучих, а затем железосодержащие материалы, проводят предварительный восстановительный подогрев по крайней мере части железосодержащих материалов путем сжигания кислородом по крайней мере частично летучих составляющих и углерода из дополнительно вводимых в печь углеродсодержащих материалов с высоким содержанием летучих. Затем зажигают и окисляют часть железосодержащих материалов в центральной зоне печи, вводят оставшуюся часть шлакообразующих материалов и производят окислительный нагрев и рафинирование расплава. Реализация настоящего изобретения способствует защите скрапа от окисления во время цикла расплавления. Подача горячих продуктов сжигания в нижнюю часть скрапа создает условия для его непрерывного нагрева, предохраняет от охлаждения первую порцию расплава при его соприкосновении с более холодным днищем сталеплавильного агрегата, что обеспечивает более высокую термическую эффективность процесса, способствует снижению износа огнеупорной футеровки, увеличению выхода годного металла и повышению производительности процесса.Usage: in the field of ferrous metallurgy in the production of steel in a furnace, the walls of which, at least partially, are lined with refractories, namely in an oxygen converter and an electric arc furnace that processes a metal charge. The invention can be used to produce steel from a solid iron-containing mixture alone or when molten iron-containing metal is loaded as part of an iron-containing material. The solid metal charge may consist of various types of iron-containing materials, such as steel scrap, cast iron, sponge iron in the form of pellets, pieces, briquettes, etc. The inventive method of steel production includes loading into a lined furnace slag-forming and iron-containing materials, oxygen supply, melting of iron-containing materials, overheating of the melt to the temperature of release and subsequent release. First, part of the slag-forming materials is loaded, carbon-containing materials with a low content of volatile materials are placed on them, and then iron-containing materials are preliminarily reheated at least part of the iron-containing materials by oxygen burning at least partially volatile components and carbon from additional carbon-containing materials introduced into the furnace with high volatile content. Then, part of the iron-containing materials is ignited and oxidized in the central zone of the furnace, the remainder of the slag-forming materials is introduced, and the melt is oxidized heated and refined. The implementation of the present invention helps to protect scrap from oxidation during the melting cycle. The supply of hot combustion products to the bottom of the scrap creates the conditions for its continuous heating, prevents the first portion of the melt from cooling when it comes in contact with the colder bottom of the steelmaking unit, which provides higher thermal efficiency of the process, helps to reduce wear of the refractory lining, increase the yield of metal and increase process performance.
