Изобретение относитс к области черной металлургии, в частности к управпенш напр жений в кладке свода мартеновской печи.The invention relates to the field of ferrous metallurgy, in particular, to the control of stresses in the laying of the open-hearth furnace.
Наиболее близким к олисьшаемому нзобретению по технической суишости и достигаемому результату вл етс устройств во ГИ дл регулировани напр жений в арочном своде мартеновской печи, содержащее термопары, установленные в кладке свода, соединенные через вторичны прибор и регул тор с дросселем. Р«;ход охладител регулируют в зависимости от температуры кладки свода, что предотвращает перегрев и оплавление свода, The closest to the technical description of the proposed invention and the achieved result is the devices in the GI for regulating the stresses in the arched vault of the open-hearth furnace, containing thermocouples installed in the laying of the roof, connected via a secondary device and regulator with a choke. P "; the course of the cooler is regulated depending on the temperature of the laying of the arch, which prevents overheating and melting of the arch,
Однако такое устройство не предотвращает износа свода от сколов свободного кирпича,However, such a device does not prevent the arch from chipping free bricks,
Цель изобретени состоит в повышени стойкости свода.The purpose of the invention is to improve the durability of the vault.
Поставленна цепь достигаетс тем, что вход вторичного прибора в предлагаемом устройстве соединен с уровнемером, установленным в своде печи.The delivered chain is achieved by the fact that the input of the secondary device in the proposed device is connected to a level gauge installed in the furnace roof.
На чертеже представлено устройство дл регулировани напр жений в ароШом своде плавильной печи.The drawing shows a device for regulating the stresses in a bowl of a smelting furnace.
Устройство состоит из уровнемера 1, подключенного к вторичному прибору 2, соединенному с программным регул тором 3, выход которого соединен с дросселем 4 охладител . Во врем плавки в своде печи возникают механические напр исени , завис щие от теплового режима свода. Это приводит к тому.что измен етс положение пучка свода, характеризующее величину механических напр жений в последнем.The device consists of a level gauge 1 connected to a secondary device 2 connected to a program controller 3, the output of which is connected to a cooler 4 choke. During smelting, mechanical stresses arise in the furnace roof, depending on the thermal regime of the roof. This leads to the fact that the position of the beam of the vault, which characterizes the magnitude of the mechanical stresses in the latter, changes.
Изменение положени пучка свода контролируетс уровнемером, посылающим электрический импульс на вторичный прибор который через программный регул тор подает команду на дроссельное устройство об изменении подачи количества охлаждающей среды.The change in the position of the roof beam is controlled by a level gauge, which sends an electrical impulse to the secondary device which, through the program controller, sends a command to the throttle device to change the amount of cooling medium.
Регулирование ведетс по заранее рассчитанной программе, учитывающей изменение температуры свода в течение каждой плавки, а также в соответствии с откло-The regulation is carried out according to a previously calculated program that takes into account the change in the temperature of the roof during each heat, and also in accordance with the deviation
