Abstract

A cold-rolled strip steel surface quality management system and method, relating to the technical field of cold-rolled strip steels. For the shortages of existing cold-rolled strip steel surface quality on-line detection systems, defect samples are established, a cold-rolled strip steel surface quality defect processing countermeasure table is established, cold-rolled strip steel surface quality detection and quality improvement are associated, and cold-rolled strip steel surface defects and the defect samples are paired to determine the strip steel surface quality grade of a cold-rolled strip steel surface defect, thereby guiding the improvement of a production technique and improving cold-rolled strip steel surface quality. Besides, abnormal samples are removed using an angular distance method to improve the labeling accuracy rate of the defect samples.

Description

technical field [0001] The invention belongs to the technical field of cold-rolled steel strips, and in particular relates to a surface quality management system and method for cold-rolled steel strips. Background technique [0002] As automobiles, home appliances and other products have higher and higher requirements on the surface quality of strip steel, enterprises pay more attention to the surface quality of cold-rolled steel strip. All large-scale domestic steel enterprises are equipped with an online detection system for strip surface quality on cold-rolled production lines. On-line detection to identify 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 not enough, resulting in a low recognition rate of the strip surface quality online inspection system; 2. After steel surface quality defects, there is a ...
