Description
Известны способы выравнивани температуры дуть в кольцевом воздухопроводе доменной печи путем двустороннего или многоструйного подвода смесительного воздуха в пр мой воздухопровод гор чего дуть , однако такими способами неравномерность распределени температур полностью пе ликвидируетс .Methods are known for equalizing the temperature of blowing in the annular air duct of a blast furnace by means of a double-sided or multi-jet supply of mixing air to a direct air duct for hot blast, however, with these methods the uneven distribution of temperatures is completely eliminated.
Предложенный способ отличаетс тем, что разность температур в двух диаметрально противоположных точках кольцевого воздухопровода поддерживают близкой к нулю путем изменени положени дроссел , установленного в месте разветвлени смесительного воздухопровода.The proposed method is characterized in that the temperature difference at two diametrically opposite points of the annular air duct is maintained close to zero by repositioning the throttle positioned at the branch point of the air duct.
Предлагаемый способ по сн етс чертежом .The proposed method is illustrated in the drawing.
На .регул тор 1 поступают сигналы от термопары 2 и от задатчика 3. В зависимости от рассогласований этих сигналов регул тор воздействует на июполнительпый механивм 4, переставл ющий дроссель 5.The controller 1 receives signals from thermocouple 2 and from the setter 3. Depending on the mismatch of these signals, the controller acts on the four-way mechanism 4, interchanging the choke 5.
TepMoniapbi б и 7, расположен;ные в двух диаметралыпо противоположных кольн/евого воздухопровода 8 :на одинаковом удалении от места врезки в него пр мого воздухопровода 9, подключены встречпо к регул тору 10. Последний воздействует на исполнительный механизм 11, который переставл ет дроссель 12, установленный в месте разветвлени смесительного воздухопровода 13, так чтобы разность показаний термопар 6 и 7 была равной или близкой к пулю.TepMoniapbi b and 7, located in two diameters of opposite koln / evuy air duct 8: at the same distance from the inset of the direct air duct 9 into it, connected to the regulator 10. The latter acts on the actuator 11, which rearranges the throttle 12 installed at the branch point of the mixing duct 13, so that the difference between the readings of thermocouples 6 and 7 is equal or close to the bullet.
