Изобретение относитс к черной металлургии , кодКретнее к получению стали в многоподовых лечах.The invention relates to ferrous metallurgy, the code for obtaining steel in multi-hearth hedges.
Известны Двух ва«ные мартеиозсхие печи, позвол ющие использовать тепло отхс-д н1;1х rasoiB дл :На.грева шихты.The two-known marthic furnaces are known, which allow the use of heat from the heat source to 1; 1x heat for: On heating the charge.
OanaiKO тажие печи имеют позышенный угар железа и низкую производительность, ов занную с .медленным разогревом загружаемой в лечь шихты.OanaiKO tajie furnaces have a flawless iron loss and low productivity associated with slow heating of the charge loaded into the bed.
Цель изобретени - увеличить выход годного и производительность печи.The purpose of the invention is to increase the yield and productivity of the furnace.
Это достигаетс тем, что скрал расплавл ют в токе газообразного топлива, нагретого до температуры выше тем1нературы ллащлени скрала, а сжигают толливо на 1зхсде его в смежную ванну.This is achieved by scrapping the melt in a stream of gaseous fuel heated to a temperature higher than that of the scrail, and burning in a flash at its place in the adjacent bath.
Преимущественно ислользуют углеводородное толливо, налример природный газ, та« как науглероживание скрала способствует его оллавлению. Папревают толливо до 1800- 2300° С с помощью .плазмотронов известной конструкции, размещенных на своде печи. После использовани части тепла толли.ва дл оплавлени скрапа толливо подают во вторуюPreferably, hydrocarbon oil is used, nalimer natural gas, such as the carbonization of scratum contributes to its fusion. Papreyut is poured to 1800–2300 ° C with the help of plasma torches of known design, placed on the roof of the furnace. After using part of the heat of tolly. In order to melt the scrap, it is poured into the second
ванну, на входе которой установлены устройства дл подачи воздуха или кислорода дл сжигани топлива и окиси углерода, выдел ющейс из ванны. Благодар разложению толлива с выделением сажистого углерода во второй ванне создаетс факел с высокой светимостью , что увеллчивает теллоотдачу ванны. ПрИМенение предложенного способа увеличивает эффективность сталеплавильного лроцесса , уменьшает удельный расход огнеупоров , снижает пылевыделение, что позвол ет улростить газоочистку.a bath at the entrance of which devices for supplying air or oxygen for burning fuel and carbon monoxide released from the bath are installed. Due to the decomposition of tolly with the release of black carbon in the second bath, a torch with high luminosity is created, which increases the recoil of the bath. The application of the proposed method increases the efficiency of the steelmaking process, reduces the specific consumption of refractories, reduces dust emission, which makes it possible to improve gas purification.
Предмет .изобретени Subject matter
Способ выллавки стали в двухванной лечи , включающий совмещение нагрева скрапа в одной ванне с рафинированием стали в другой , отличающийс тем, что. с целью увеличени выхода годного и производительности печи, скрал расплавл ют в газообразного топлива, нагретого до температуры выше температуры плавленп скрапа, а сжигают ТОЛЛИ1ВО на входе его в смежную ванну.The method of catching steel in a two-bath cure, including combining the heating of scrap in one bath with the refining of steel in another, characterized in that. In order to increase the yield of the furnace and the productivity of the furnace, the scrapper is melted into gaseous fuel heated to a temperature above the melt temperature of the scrap, and burned TOLLI1BO as it enters the adjacent bath.
