(54) СПОСОБ КОНТРОЛЯ ПОЛОЖЕНИЯ ФУРМЫ ОТНОСИТЕЛЬНО ГРАНИЦЫ ШЛАК - МЕТАЛЛ(54) METHOD FOR CONTROLLING THE POSITION OF A LATCH WITH RESPECT TO THE BORDER OF SLAG - METAL
1one
Изобретение относитс к черной металлургии , конкретнее « контролю положени фурмы в сталеплавильном агрегате.The invention relates to ferrous metallurgy, more specifically to "controlling the position of the tuyere in a steelmaking unit.
Известны способы контрол положени фурмы в момент погружени ,в ванну сталеплавильного агрегата путем подачи газа через сопла фурмы и измерени давлени в фурму. Момент погружени фурмы в металл определ ют по возрастанию давлени при приближении фурмы к поверхности ванны.Methods are known for controlling the position of the tuyere at the time of immersion into the bath of the steel-smelting unit by supplying gas through the tuyere nozzles and measuring the pressure in the tuyere. The moment the tuyere is immersed in the metal is determined by the pressure increase as the tuyere approaches the bath surface.
Иедостаток известного способа состоит в низкой точности, св занной с колебани ми давлени в газовой магистрали.The disadvantage of this method is low accuracy due to pressure fluctuations in the gas line.
Цель изобретени состоит в ловышении точности контрол .The purpose of the invention is to increase the accuracy of control.
Это достигаетс тем, что положение фурмы фиксируют при возникновении пульсации давлени газа в сопле фурмы.This is achieved by fixing the position of the tuyere when a gas pressure pulsation occurs in the tuyere nozzle.
При подаче продувочного газа через фурму, расположенную над расплавом, пульсации давлени отсутствуют. При опускании фурмы пульсации возникают е момент перехода наконечника фурмы из шлака в металл. В этотWhen purging gas is introduced through the tuyere located above the melt, there are no pressure pulsations. When lowering the pulsation tuyere, there arises the moment when the tuyere tip passes from slag to metal. In that
момент на шкале прибора, контролирующего положение фурмы в рабочем пространстве, отмечают значение, соответствующее погружению фурмы в металл. В дальнейшем превышение или заглубление фурмы в металл может быть установлено .по сельсину относительно отмеченной точки.the moment on the scale of the device controlling the position of the tuyere in the working space, note the value corresponding to the immersion of the tuyere in the metal. In the future, the excess or depth of the tuyere in the metal can be established. According to the selsyne relative to the marked point.
Использование предлагаемого способа позвол ет оптимизировать процесс продувки металла , что приводит к более .полному усвоению кислорода, повышает производительность агрегата и увеличивает выход годного металла .Using the proposed method allows to optimize the process of metal purging, which leads to a more complete absorption of oxygen, increases the productivity of the unit and increases the yield of the suitable metal.
Предмет изобретени Subject invention
Способ контрол положени фурмы относительно границы шлак - металл, включающий подачу газа через сопла и измерение давлени газа в фурме, отличающийс тем, что, с целью увеличени точности контрол , положение фурмы фиксируют при возникновении пульсаций давлени в сопло фурмы.The method of controlling the position of the tuyere relative to the slag-metal boundary includes gas supplying through nozzles and measuring gas pressure in the tuyere, characterized in that, in order to increase control accuracy, the position of the tuyere is fixed when pressure pulsations occur in the tuyere nozzle.
