Description
Известны устройства дл ввода кислорода или других газов, газовых смесей и порошкообразных материалов в смеси с газом в ванну качающейс мартеновской печи через ее свод. Однако эти устройства имеют р д недостатков. При разливке стали подъем фурмы зависит от рассто ни от места подвески фурмы до ролика, устанавливаемого на металлоконструкции печи. Это мешает вести поверхностную продувку металла в начале плавлени и в услови х перегрузки печей. При скачивании шлака необходимо прекращать продувку и выводить фурму из печи.Devices are known for introducing oxygen or other gases, gas mixtures and powdered materials in a mixture with gas into the bath of an open-hearth furnace through its roof. However, these devices have several disadvantages. When casting steel, the raising of the tuyere depends on the distance from the place of suspension of the tuyere to the roller mounted on the metal structures of the furnace. This makes it difficult to conduct a superficial purge of the metal at the beginning of melting and under conditions of furnace overload. When downloading slag, it is necessary to stop the blowing and remove the lance from the furnace.
Предлагаемое устройство отличаетс от известных тем, что на фурме выше точки подвески установлен элемент, служащий поворотной опорой, перемешающейс внутри воронки, св занной с металлоконструкци ми печи. Это обеспечивает свободное перемещение фурмы при наклонах печи.The proposed device differs from the known ones in that the lance above the suspension point is fitted with an element that serves as a pivot bearing mixing inside the funnel associated with the metal constructions of the furnace. This ensures the free movement of the tuyere when the stove is inclined.
На чертеже изображены три характерные последовательные положени печи с введенной в нее фурмойУстройство состоит из фурмы 1 со специальным элементом опоры а, перемещающимс с проворотом по специальной поверхности 2, сводовой водоохлаждаемой амбразуры 5, гибкого звена подвески 4, блока 5 в качающейс обойме и кронштейна 6, закрепленного на подкрановой балке печного пролета цеха.The drawing shows three characteristic consecutive positions of the furnace with the tuyere inserted into it. The device consists of lance 1 with a special support element a moving along the special surface 2, a water-cooled archway 5, a flexible suspension link 4, a block 5 in a swinging cage and a bracket 6, fixed on the crane beam of the furnace span of the workshop.
Наличие опоры а на фурме позвол ет, благодар свободному перемещению опоры но поверхности 2, устанавливаемой на металлоконструкци х печи, наклон ть печь как на сталь, так и на щлак с введенной в печь фурмой, а также допускает значительные изменени положени фурмы по высоте при наклонных положени х печи.The presence of a support on the lance allows, due to the free movement of the support on the surface 2 mounted on the metal structures of the furnace, to incline the furnace both on the steel and on the slag with the lance inserted into the furnace, and also allows significant changes in the position of the tuyere in inclined furnace positions.
