Description
Изобретение относитс к области черной металлурпии, .в частности, к способам регулировани теплового состо ни до енной плавки. Известный способ регулировани таплового состо ни домениой плашси путем изменени расхода дополнительного то1пли1ва, вдуваемого в горн печи, в зависимости от содержани кремни в чугуне, не устанавливает оптишалвных величин из1манвни расхода .мазута , примененного в качестве дополнительного топлива, в зависимости от содержани кремни в чугуне. Цель изобретени - повысить производительность лечи и уменьшить расход кокса. Это достигает1с тем, что при изменении содержани иремни в чу|Гу)не на 0,1Vo расход мазута измен ют в количестве 0,6-1,5 гм дуть . Предлагаемый способ за|ключаетс в еледующем . Вместе с дутьем в доменную печь при выплавке литейных чугуиов в процессе ее работы подают мазут в количестве 10-30 г1м дуть . При этом И1нтенси.вность горени кокса на фурме посто нна. При из:менении содержани кремни на О,Н/о расход мазута из1мен ют в количестве 0,6-1,5 г/м дуть . Ход доменной платаки регулируют величиной рудной по|дачи, системами загрузки и повышением давлени газа под колошником. Предмет .изобретен и Способ регулировани теплового состо ни доменной 1пла1вки, включаюший .изменение расхода дополнительного таплива, вдуваемого в горн печи, Б за1зиси.мости от содержани кремни в чугуне, отличающийс тем, что, с целью повышени нроиз1водительности печи и снижени расхода какса, при изменении содержани кремни в чугуне на О, расход мазута измен ют в количестве 0,6-1,5 г/м ду.ть .The invention relates to the field of ferrous metallurgy, in particular, to methods for regulating the thermal state of the heat of fusion. The known method of controlling the tampl state of the domain plate by changing the flow rate of the additional toply blown into the furnace furnace, depending on the silicon content in the pig iron, does not set the optimal values from the manmat of the fuel consumption used as an additional fuel depending on the silicon content in the iron. The purpose of the invention is to improve the performance of lechi and reduce coke consumption. This achieves 1 with the fact that with a change in the content of the cream in chu | gu) not by 0.1Vo, the consumption of fuel oil changes in the amount of 0.6-1.5 gm to blow. The proposed method is finalized. Together with the blast in the blast furnace in the smelting of cast iron in the process of its operation, fuel oil is fed in an amount of 10-30 g1m to blow. At the same time, the intensity of the combustion of coke on the tuyere is constant. When from: changing the silicon content on O, N / o, the consumption of fuel oil is 1 changing in the amount of 0.6-1.5 g / m to blow. The stroke of the blast furnace is regulated by the magnitude of the ore supply, loading systems and the increase in gas pressure under the furnace top. The subject of the invention is also a method for regulating the thermal state of a blast furnace, including the change in the flow rate of the additional fuel blown into the furnace furnace, due to the silicon content in the pig iron, in order to increase the furnace's efficiency and changing the silicon content in the pig iron on 0, the consumption of fuel oil varies in the amount of 0.6-1.5 g / m d.t.
