СПОСОБ РЕГУЛИРОВАНИЯ РАСХОДА ВОССТАНОВИТЕЛЬНОГО ГАЗА В ДОМЕННОЙ ПЕЧИMETHOD FOR REGULATING REDUCING GAS FLOW IN THE DOMAIN FURNACE
1one
Известен способ регулировани расхода восстановительного газа в доменной печи путем установки регул торов количества или регул тора отношени .There is a known method for controlling the flow of reducing gas in a blast furnace by installing quantity controllers or a ratio control.
Цель изобретени - сокращение посто нного расхода восстановительных компонентов дуть при колебани х давлени газа.The purpose of the invention is to reduce the constant consumption of reducing components to blow when the gas pressure fluctuates.
Предлагаетс достигать эту цель путем поддержани перепада давлени газа перед процессом конверсии на критическом уровне, обеспечивающем их звуковую скорость, когда расход газа становитс независимым от колебаний давлени газа в доменной печи.It is proposed to achieve this goal by maintaining the gas pressure drop before the conversion process at a critical level, ensuring their sound speed when the gas flow rate becomes independent of the pressure fluctuations of the gas in the blast furnace.
На чертеже показана диаграмма зависимости расхода газа от отношени давлени ниже и выше по потокуThe drawing shows a diagram of the dependence of the gas flow on the ratio of pressure downstream and upstream
В области А расход не зависит от перепада. В области В кривые С, D, Е показывают скорости в зависимости от отношени давлений.In area A, the flow rate does not depend on the differential. In region B, curves C, D, E show speeds as a function of pressure ratio.
Подача в печь при посто нном расходе восстановительного -газа обеспечивает посто нный приход тепла на единицу чугуна при нарушепи х хода печи, которые про вл ютс в колебани х давлени дуть . Это, в свою очередь, обеспечивает выплавку более посто нных по качеству чугунов.The supply to the furnace at a constant flow rate of reducing gas ensures a constant flow of heat per unit of cast iron in the event of disturbances in the furnace, which are manifested in pressure fluctuations to blow. This, in turn, ensures the smelting of more permanent cast iron.
