Problems solved by technology
At present, in many iron and steel production enterprises, the method of manual fixing and manual clamping measurement is still used for the measurement of strip warpage defects. The strip must be unloaded and re-clamped and fixed, especially when the length of the strip to be sampled is large and the specification of the strip is thin, it is very inconvenient to measure the C warpage defect

The invention discloses a device suitable for measuring warping defects of cold-rolled strip steel. The device comprises a supporting base, two strip steel clamping mechanisms of the same structure, a vertical measurement platform, verticality adjustment knobs and a vertical plate, wherein the verticality adjustment knobs are arranged on four corners of a supporting base, the vertical plate perpendicular to the supporting base is arranged in the middle of the supporting base, the upper part of the vertical plate is connected with the vertical measurement platform by means of a central shaft, and the surface of the other side of the vertical measurement platform is provided with horizontal and vertical dial gauges near side edges; and the two strip steel clamping mechanisms of the same structure are arranged on horizontal and vertical surfaces, opposite to the dial gauges, on the vertical measurement platform. The device improves the operating efficiency, reduces cost, is convenient and safe in measurement of the warping defects of the strip steel, can satisfy continuous measurement of L warping defect and C warping defect of the strip steel, and facilitates the technician to read length and width data of the strip steel by means of scales of the vertical measurement platform, so that the warping measurement operation of the strip steel proceeds in order.
Description
technical field [0001] The invention belongs to the technical field of steel strip measurement in the iron and steel industry, in particular to a device and a measurement method suitable for measuring warpage defects of cold-rolled strip steel. Background technique [0002] The warping defect of cold-rolled strip steel is one of the main defects affecting the quality of strip steel products. Warpage defects are divided into L warpage and C warpage. During the strip rolling process, the extension of the upper and lower surfaces of the strip steel is inconsistent, so that the strip steel shows upward or downward warpage along the length direction, which is L warpage. The upward or downward warping of the strip along the width direction is the C warping defect. The severity of strip warpage defects is represented by warpage values. Accurate measurement methods and reasonably designed measurement devices are helpful for technicians to monitor the occurrence of strip steel defec...
