Abstract

The invention relates to a device and method for measuring whether strip steel deflects or not. The device comprises a WS side guide ruler, a DS side guider ruler, a first control device and a second control device, wherein the WS side guide ruler is controlled by the first control device, and the DS side guide ruler is controlled by the second control device. When the WS side guide ruler and the DS side guide ruler are attached together, the display value of a displacement sensor is zero; and as the WS side guide ruler and the DS side guide ruler move towards the two sides correspondingly, the value of the displacement sensor is gradually increased until the WS side guide ruler or the DS side guide ruler reaches the maximum opening degree, and the position of the strip steel is adjusted through the value of displacement monitored by the sensor. The device and method for measuring whether the strip steel deflects or not have the advantages that movement of the WS side guide ruler and the DS side guide ruler is controlled by a hydraulic cylinder, damage to the guide rulers and equipment is avoided, movement parameters are provided by the sensor to provide a basis for the adjustment work, and the plate form is improved.

Description

technical field [0001] The invention relates to a method for measuring strip steel deviation, which is suitable for the situation that the opening degree of the guide bar of a rolling mill is controlled by hydraulic pressure. Background technique [0002] When rolling strip steel, it is hoped that the centerline of the strip steel coincides with the rolling centerline of the rolling mill. This is an ideal expectation, which cannot be realized in practice, but keep the centerline of the strip steel and the rolling centerline within a reasonable range , is achievable, but requires real-time measurement of strip deviation. [0003] The entrance of the finishing mill is equipped with a guide bar, which is used to guide the rolled piece (strip steel) into the rolling mill in a centered state and limit the swing of the strip steel during the rolling process. Usually, the guide bar is easy to scratch the strip steel when it is working, thus damaging the guide bar. Contents of th...
