Предлагаемое изобретение относитс  к черной металлургии.The present invention relates to ferrous metallurgy.

Известен способ выплапк) стали с двухванной печи по основному авт. св. № 448228, включающий поочередную продувку металла в одной из ваин и прогрев скрапа в другой ванне теплом технологических газон и углеводородного тонлив;, при котором, с целью подогрева топлива, его реформации, улучп1епи  аэродинамики газов, повышени  стойкости свода и увеличени  доли скрапа в металлонп-1хте , углеводородиое топливо ввод т в поток технологических газов, а образуюп1уюс  при этом газовую смесь Нат1равл 1от в ванну с скрапом, в которой ее сжигают.The known method vyplapk) steel with two-bath furnace on the main ed. St. No. 448228, which includes alternately purging the metal in one of the wafers and heating the scrap in another bath by the technological lawn and hydrocarbon smelting; in First, the hydrocarbon fuel is injected into the process gas stream, and the gas mixture is then mixed into a bath with scrap, in which it is burned.

С целью улучшени  нагрева скрана, снижени  угара железа, повышени  стойкости свода и производительности печи по предлагаемому способу углеводородное топливо в поток технологнчееких газов нродувочной ванны ввод т в количестве 30-70% от обндего его расхода на нагрев скрапа.In order to improve the heating of the skran, reduce the iron burn, increase the durability of the vault and the furnace performance according to the proposed method, hydrocarbon fuel is introduced into the flow of process gases of the nasvodochnoi bath in the amount of 30-70% of its consumption for heating scrap.

Способ осун1,еетвл етс  следующим образом .The osun method is as follows.

В двухванной печи в одной ванне ведут продувку металла кислородом, а в другую ванну в это же врем  загружают скрап и затем прогревают его технологическими газами и топливом. В продувочную ванну в поток образующихс  в результате окислени  углерода техпологичееких газов ввод т, нанрнмер , 1000 нрнродного газа, что составл ет 50% от общего часового расхода его на нагрев скрапа, а остальное количество - 1000 подают непосредственно в ванну с скрапом в поток газовой смеси, постунаюHieii из продувочной ванны. Гор чне составл  юнще газовой смеси и введенное в рабочее пространство топливо сжигают нродупкойIn a two-bath furnace in one bath, the metal is purged with oxygen, and the other is charged with scrap at the same time and then heated by process gases and fuel. Into the purge bath, 1000 nanograms of gas, which accounts for 50% of the total hourly consumption of it for heating scrap, is introduced into the stream resulting from the oxidation of carbon, which accounts for 50% of the total hourly expenditure for heating scrap, I put Hieii from the purge bath. A hot gas mixture and the fuel introduced into the working area is burned with a nozzle.

кислородом и кислородом, поступаюпдим 3 печь с атмосферным воздухом. Количество природного газа, вводнмого в продувочную ванну, регулируетс  в зависи.мости от темиературы свода, котора  должна составл ть воoxygen and oxygen, coming in a 3 oven with atmospheric air. The amount of natural gas introduced into the purge bath is regulated depending on the temperature of the dome, which should be

врем  иродувки 1550-1650°С. Така  темнература обеснечиваетс  за счет ввода в поток технологических газов продувочной ванны нриродного газа в количестве 30-70% от общего его расхода на нагрев скрапа.time of vacuum cleaning is 1550-1650 ° С. Such an environment is depleted due to the introduction of a natural gas purge bath of natural gas in the amount of 30-70% of its total waste for heating scrap.

Благодар  подаче части нриродного газа в продувочную ванну дл  нагрева и реформации его и введению части топлива непосредственно в ванну нагрева скрана, в рабочнх пространствах обеих ванн поддерживаютс By supplying a part of the natural gas to the purge bath for heating and reforming it and introducing a portion of the fuel directly into the cranium heating bath, the working spaces of both baths are maintained

оптимальные с точкн зрени  стойкости свода и проведени  те.кнологическнх процессов температурные услови . С одной стороны предотвращаетс  как перегрев, так и переохлаждение свода, а с другой стороны, создаютс optimal from the point of view of the durability of the arch and the conduct of technological processes temperature conditions. On the one hand, both overheating and overcooling of the vault is prevented, and on the other hand,

услови  дл  интенсификации нагрева лома. 3 Предлагаемый способ позвол ет снизить угар железа, повысить стойкость кладки свода и увеличить производительность печи. Предмет изобретени . Способ выплавки стали в двухванной подовой печи по авт. св. N° 448228, о т л и ч а го4 щийс  тем, что, с целью повышени  стойкости свода и производительности печи, углеводородное топливо в поток технологических газов продувочной ванны ввод т в количест 30-70% от общего его расхода на нагрев скрапа, conditions for the intensification of scrap heating. 3 The proposed method makes it possible to reduce the iron frenzy, to increase the durability of the brickwork and to increase the productivity of the furnace. The subject matter of the invention. The method of steelmaking in a two-bath hearth furnace according to ed. St. N ° 448228, about tl and h and 4, in order to increase the durability of the roof and the productivity of the furnace, the hydrocarbon fuel is introduced into the flow of process gases of the purge bath in the amount of 30-70% of its total waste for heating scrap,
