Device and method for detecting broken bean defects on checker plate of hot-rolled Bepsi-Tai surface inspection system

Abstract

The present invention discloses a detection apparatus and a method for hot rolling Parsytec surface detection system checkered plate bean damage defect, and belongs to the technical field of hot rolling strip steel surface detection. The detection method comprises: 1, configuring a file to increase a checkered plate material set; 2, applying a standard edge portion detection module; 3, setting the detection sensitivity of the traditional hot rolling special area detection module to 0%, and setting the texture fitness to 100%; 4, adopting a sensitive area detection module; 5, collecting 30-50 matrix samples from a normal checkered base plate, and collecting 50-80 defect samples from a sample having bean damage defect; and 6, adopting the post-processing file setting of the system software program to make the system have the operation interface alarm function on the checkered plate bean damage defect. With the detection method, the system defect overflow can not be caused, and the batch quality accidents caused by roller bean damage are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of surface detection of hot-rolled steel strips, in particular to a detection device and method for broken bean defects of pattern plates of a hot-rolled PepsiCo surface detection system. Background technique [0002] As a hot-rolled special plate, checkered plate is mainly used for structural building anti-skid, vehicle use and door panel decoration materials, etc. At present, the defect that affects the surface quality of the checkered plate is mainly the broken bean defect of the checkered plate. This defect is mainly due to the unstable rolling of the thin gauge checkered plate, or the unreasonable design of the checkered roll, which causes the bean grains of the roll to be damaged, and the broken bean grains in the subsequent rolling Printed onto the strip steel. If the defect is not found in time, it is easy to cause batch quality accidents. And broken bean defects not only affect the appearance, but...

Problems solved by technology

At present, the defect that affects the surface quality of the checkered plate is mainly the broken bean defect of the checkered plate. This defect is mainly due to the unstable rolling of the thin gauge checkered plate, or the unreasonable design of the checkered roll, which causes the bean grains of the roll to be damaged, and the broken bean grains in the subsequent rolling printed on strip steel

If the defect is not found in time, it is easy to cause batch quality accidents

And broken bean defects not only affect the appearance, but the serious broken bean is prone to stress concentration and cracks, which affects customer use and causes quality objections

[0003] At present, due to the checkered plate using the traditional hot-rolled surface defect detection method, all the bean grains on the entire substrate of the checkered plate are detected as defects, resulting in too many defects detected by the system, and normal defect processing cannot be performed. The detection rate of broken bean defects is less than 50%, which may lead to overflow of system defects, and it cannot guarantee 100% detection of broken bean defects on the pattern plate, and batch quality accidents caused by roll broken beans will occur
