Claims (1)

Способ получения чугуна и ферросплавов в низкошахтной печи или бесшахтном реакторе, включающий непрерывную или периодическую загрузку в печь пылеватых и (или) окускованных рудных материалов, флюсов, кокса и (или) угля, кислородное и воздушное дутье через нижние фурмы в коксовую насадку выше слоев жидких металлического сплава и шлака, непрерывный или периодический выпуск сплава и шлака через летки, отличающийся тем, что 5-95% кислородного дутья подают через верхние дополнительные фурмы поверх уровня засыпи шихты, что обеспечивает полное или частичное дожигание в печи образующегося газа.A method of producing cast iron and ferroalloys in a low-shaft furnace or shaftless reactor, comprising continuously or periodically loading dusty and (or) agglomerated ore materials, fluxes, coke and (or) coal, oxygen and air blasting through lower tuyeres into a coke nozzle above the layers of liquid metal alloy and slag, continuous or intermittent release of alloy and slag through a notch, characterized in that 5-95% of the oxygen blast is fed through the upper additional tuyeres above the charge charge level, which ensures complete or partial afterburning of the resulting gas in the furnace.
