Abstract
1. Способ выплавки стали в дуговой сталеплавильной печи, включающий завалку шихты, подогретой в шахтном подогревателе, ее расплавление, проведение окислительного и восстановительного периодов плавки и выпуск металла из печи, отличающийся тем, что в течение всей плавки в подсводовое пространство подают природный газ, а дожигание продуктов неполного горения газа обеспечивают путем ввода кислорода в шахту подогревателя шихты через отверстия в боковых стенах шахты. ! 2. Устройство для выплавки стали представляет собой дуговую сталеплавильную печь с шахтным подогревателем шихты, установленным над сводом, причем в своде печи выполнены отверстия для ввода газа, расположенные равномерно по полуокружности против шахтного подогревателя, а в боковых стенах шахты подогревателя шихты выполнены отверстия для ввода кислорода, расположенные на расстоянии от 0,3 до 0,7 высоты шахты. 1. A method for smelting steel in an arc steel-making furnace, including charging a charge heated in a shaft heater, melting it, conducting oxidation and reduction periods of melting and tapping metal from the furnace, characterized in that during the entire melting, natural gas is fed into the under-roof space, and Afterburning of the products of incomplete gas combustion is ensured by introducing oxygen into the charge heater shaft through holes in the side walls of the shaft. ! 2. The device for steel smelting is an arc steel-making furnace with a shaft charge heater installed above the roof, and in the roof of the furnace there are holes for gas injection, located evenly along a semicircle opposite the shaft heater, and holes for oxygen supply are made in the side walls of the charge heater shaft located at a distance of 0.3 to 0.7 of the height of the shaft.
