Problems solved by technology

However, the above-mentioned patent uses the pressure-sensitive layer to sense the pressure, and then detects the flatness. However, the above-mentioned detection process is cumbersome, and only one local area of ​​the steel plate can be detected at a time. Each inspection requires the steel plate to be in the state of stopping transportation, the inspection efficiency is low, the production cycle is prolonged, and the integrity of the unevenness information obtained is low, and the next step of processing cannot be carried out based on the inspection information

Abstract

The invention discloses steel plate online flatness detection equipment and a detection method thereof, and belongs to the technical field of steel plate flatness detection. The steel plate online flatness detection equipment comprises a display, a flatness analysis unit, a laser source, a camera, a hot rolling mill, a laser projector, optical fibers and a projector support; and a steel plate is in rolling connection with the middle portion of the hot rolling mill, the hot rolling mill comprises a rolling device and a conveying device, the projector support is arranged above the conveying device, the camera and the laser projector are both installed on the projector support, the laser projector projects light rays to the upper surface of the steel plate, the light rays are in a grid shape,the laser projector is connected with the laser source through the optical fibers, the laser source is electrically connected with the flatness analysis unit, and the flatness analysis unit is electrically connected with the display. Steel plate surface unevenness detection is rapid and comprehensive, information such as the position, the size and the degree of steel plate surface unevenness canbe obtained, and enough data support is provided for secondary machining.

Description

technical field [0001] The invention relates to the technical field of steel plate flatness detection, in particular to an online steel plate flatness detection device and a detection method thereof. Background technique [0002] Due to the change of internal chemical composition, the uneven distribution of stress, and the limitation of rolling process and equipment, etc., the surface of hot-rolled steel plate may have depressions, protrusions, scratches, bubbles, etc., which will affect the flatness of the surface. Therefore, it is necessary to In the hot rolling production line, the surface flatness of the rolled steel plate is detected, so as to obtain the quality change of the steel plate in real time and make necessary adjustments. [0003] Patent No. CN201720795306.X discloses a flatness detection device for steel plates, including a workbench, slide rails, beams, digital displays and detection rods. The workbench is equipped with a lifting mechanism to move vertically...
