Embodiment Construction
[0027] The technical solutions in the specific embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings and clear examples. The following examples are used to illustrate the present invention, but are not used to limit the scope of the present invention.
[0028] The on-line measurement system of side bending of steel plate after rolling consists of 2 grating sensors, model: CIKENN-5, L-shaped chute, section size 35mm*35mm; 1 high-speed linear camera, camera model: DALSA LA-GM-08K08A , line frequency 20kHz, resolution 8192; 1 set of blue line laser transmitter model: LWBVIS-5-DH, wavelength 450nm; incremental encoder, model: Avtron-HS35, control system, I7-5600, 4k resolution rate composition. Along the moving direction of the steel plate, a high-speed line camera is placed on one side of the roller table, and a grating sensor is placed before and after the high-speed line camera. According to the moving dire...

Abstract
The invention relates to a method for measuring the length and side bending of hot steel plates during the rolling process. The method adopts a high-speed line array camera, uses a grating signal to trigger the shooting of steel plate images, and applies an image processing algorithm to perform edge extraction. By measuring the moving steel plate According to the measurement, the length of the steel plate and the amount of side bending are determined based on the edge points, width center line, strip body and scanning line scanning area. The invention realizes online measurement of the length and side bending of the hot steel plate after rolling during motion. The measurement system has simple hardware configuration, efficient and accurate calculation method, can reflect the width information of the strip in real time, and avoids the problems caused by manual measurement. Error; it has the characteristics of fast speed and high precision, and can quickly and accurately calculate the length and side bending of the steel plate. At the same time, it provides accurate data for subsequent sizing of the steel plate, thereby improving the product quality of the steel plate, and providing accurate data for subsequent shearing and side bending control.
Description
technical field [0001] The invention relates to the field of metallurgical automatic production and detection, in particular to a method for measuring the length and side bending of a hot steel plate in a rolling process. Background technique [0002] In the steel plate production process of the steel industry, after the hot-rolled plate and strip are rolled, due to the uneven pressure generated by the roll on the strip and the uneven temperature of the steel plate itself, the side of the steel plate is asymmetrical or side-bent. defect. Once side bending occurs in the rolling process, the light one will increase the amount of edge trimming, which will affect the yield; the severe one will cause the product to fail to meet the standard and be eliminated as a whole; serious side bending may even damage the equipment, causing the entire production line to stop production, seriously affecting Productivity. In order to solve the above problems, it is necessary to detect the de...
