Finish rolling strip steel deviation detection system and method based on binocular linear array camera

Abstract

The invention provides a finish rolling strip steel deviation detection system and method based on a binocular linear array camera, and belongs to the technical field of plate and strip rolling. The method comprises the following steps: adjusting view collinear of two linear array cameras through camera calibration, and obtaining internal and external parameters of the two linear array cameras; after the strip steel bites the steel on the current rack, triggering two linear array cameras to acquire a strip steel image of the current rack by taking a steel biting signal as a triggering signal; the image processing server carries out image processing and data calculation on the acquired strip steel image based on the acquired internal and external parameters of the two linear array cameras to obtain the real-time deviation amount of the strip steel; and displaying the real-time deviation of the strip steel on a terminal display. According to the invention, the deviation of the strip steel can be accurately detected in real time.

Description

technical field [0001] The invention relates to the technical field of sheet and strip rolling, in particular to a system and method for detecting the deviation of a finishing rolling strip steel based on a binocular line array camera. Background technique [0002] As an indispensable raw material, sheet and strip products are used in various fields such as industry, agriculture, commerce, manufacturing, etc., such as automobile manufacturing, agricultural machinery, electronic products, food packaging and equipment, etc., for our work and life. Provides great convenience. [0003] At present, my country's iron and steel production ranks first, but there is a big problem in that the overcapacity of ordinary steel, high-grade alloy steel, fatigue-resistant high-strength steel, high-temperature-resistant, radiation-resistant steel and special steel have high added value and high technology content. of high-end steel is heavily dependent on imports. The reason is that the plat...

AI Technical Summary

Problems solved by technology

The running deviation between strip steel racks is the defect of dimensional accuracy and internal stress deviation caused by the uneven three-dimensional deformation of the metal along the width direction of the rolled piece, which will not only cause quality problems of the finished product, but also affect the continuity and stability of the entire rolling process

[0005] The deviation of the strip will cause the fluctuation of the wedge index of the strip. During the thin-gauge rolling process, it is very easy to produce waves between the stands, which will affect the quality of the strip. Scratches on the steel surface, defects such as edge damage, resulting in a reduction in yield and product degradation, and damage to equipment such as rolls and guides. At present, there is no effective monitoring method for the deviation of the strip between racks. The center line offset data can be obtained at the finish rolling exit width gauge. It is based on the current production status and demand that it is particularly important to design and develop a deviation detection system between stands of the finishing rolling mill.
