Изобретение относитс к способам контрол и регулировани параметров процесса прокатки .The invention relates to methods for monitoring and controlling the parameters of a rolling process.
Известен способ измерени прогиба рабочих валков при прокатке, включающий измерение собственного прогиба рабочего валка и измерение равномерного сплющивани валков. Собственный прогиб рабочего валка определ ют путем измерени взаимного положени шеек рабочих и опорных валков, а сплющивание измер ют по усилию прокатки. Измерение полного прогиба рабочего валка по известному способу сложно и неточно.A known method for measuring the deflection of work rolls during rolling involves measuring the own deflection of the work roll and measuring the uniform flattening of the rolls. The proper deflection of the work roll is determined by measuring the relative position of the necks of the work rolls and the support rolls, and flattening is measured by rolling force. The measurement of the total deflection of the work roll by a known method is difficult and inaccurate.
С целью получени сигнала полного прогиба рабочего валка дл систем автоматического регулировани поперечной разнотолщинности полосы одновременно измер ют угол поворота щейки рабочего валка относительно станины клети и рассто ние от осевой линии клети до точки измерени угла поворота.In order to obtain a signal of full deflection of the work roll for the systems for automatic adjustment of the transverse thickness difference of the strip, the angle of rotation of the work roll cheek relative to the stand of the stand and the distance from the center line of the stand to the point of measurement of the angle of rotation are measured simultaneously.
На чертеже показана схема измерени по предлагаемому способу.The drawing shows the measurement scheme of the proposed method.
При отсутствии полосы в валках отсутствует их изгиб, а нейтральна ось, проход ща через бочку и шейки каждого рабочего валка, представл ет пр мую линию 1. Шейки валков при этом наход тс в нейтральном положении , соответствующем линии 1.In the absence of a strip in the rollers, there is no bending, and the neutral axis passing through the barrel and the necks of each work roller represents the straight line 1. The necks of the rolls are in the neutral position corresponding to line 1.
При по влении полосы в валках и усили прокатки Р происходит изгиб валков и нейтральна ось каждого валка занимает положение 2. Шейки валков при этом не изгибаютс , а проседают в направлении усили прокатки и одновременно поворачиваютс в этой же плоскости на угол ее по отнощению к своему первоначальному положению.When a strip appears in the rolls and the rolling force P occurs, the rolls bend and the neutral axis of each roll occupies position 2. The roll necks do not bend, but sags in the direction of the rolling force and simultaneously rotate in the same plane by its angle relative to its original position.
На щейке валка расположены измерители 3 угла поворота. Одновременно измер ют рассто ние от измерител до станины 4.On the cheek of the roll are gauges 3 angle. At the same time, the distance from the gauge to the bed 4 is measured.
Предложе1П1ый способ измерени изгиба валков при прокатке может быть реализован в устройстве измерени изгиба рабочих валков при прокатке. Полученный по такому способу сигнал полпого прогиба рабочих валков может быть использован в системах автоматического регулировани поперечной разнотолщинности полосы.A proposed method for measuring roll bending during rolling can be implemented in a device for measuring the bending of work rolls during rolling. The signal obtained by this method for the hollow deflection of work rolls can be used in systems for automatic adjustment of the transverse strip thickness variation.
