Abstract

The invention belongs to the technical field of cold-strip steel, and particularly relates to a cold-strip steel surface quality management system and method. To overcome the deficiency of an existingon-line cold-strip steel surface quality detection system, a defect sample is established, a cold-strip steel surface quality defect handling countermeasure table is established, the cold-strip steelsurface quality detection is associated with quality improvement, the cold-strip steel surface detects are matched with the defect sample to judge the surface quality grade of strip steel with the cold-strip steel surface quality defects, and therefore the production technology is guided to be improved, and the cold-strip steel surface quality is improved. In addition, the angular distance methodis adopted to eliminate abnormal samples, and therefore the defect sample marking accuracy rate can be improved.

Description

Technical field [0001] The invention belongs to the technical field of cold-rolled strip steel, and specifically relates to a cold-rolled strip steel surface quality management system and method. Background technique [0002] As automobiles, home appliances and other products have higher and higher requirements for the surface quality of strip steel, companies are paying more attention to the surface quality of cold-rolled strip steel. All large domestic steel companies are equipped with online strip surface quality inspection systems on cold-rolling production lines. Online detection and identification of the surface quality of cold rolled strip steel. [0003] During operation, the online strip surface quality inspection system has two limitations: 1. The number of defect samples, uniformity and marking accuracy are insufficient, resulting in a low recognition rate of the strip surface quality online inspection system; After the steel surface quality defects, the lack of strip s...
