Embodiment Construction

[0037] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0038] Such as figure 1 As shown, the method for judging the surface defects of the steel coil based on the distribution characteristics of the surface defects of the present invention comprises the following steps:

[0039] Step 1, determine the data range;

[0040] Step 2, noise data filtering;

[0041] Step 3. Standardization of the defect position of the steel coil: the coordinates of the defect on the steel coil are converted to between 0 and 1, and the length and width of the steel coil are both standardized to 1;

[0042] Step 4, steel coil meshing: divide the steel coil into head, tail, transmission side, operation side, center line, and six large areas inside the steel coil (there are overlaps between the areas);

[0043] Step 5. Determine the division scope of each region th...

Abstract

The invention discloses a method for determining the surface defects of a steel coil based on the distribution characteristics of surface defects. The method includes the following steps: 1. determining data range; 2. filtering noise data; and 3. standardizing positions of the defects of the steel coil: transforming the coordinates of the defects of a steel coil to between 0 and 1, wherein the length and width of the steel coil are standardized to first level. According to the invention, the method herein can give a quantitative description of the surface defects of the steel coil based on thedistribution characteristics, provides a new perspective for analyzing the surface defects, and completes defect classification based on the distribution characteristics of the surface defects. The method can provide data support for technical experts to track the reasons for the defects in the analysis of defects in batches and cross sets so as to increase the efficiency in determining surface defects and lower influence by manual factors on determination of defects.

Description

technical field [0001] The invention relates to a method for judging surface defects of steel coils, in particular to a method for judging surface defects of steel coils based on distribution characteristics of surface defects. Background technique [0002] Under the background of Baosteel's smart manufacturing, Baosteel has built a process quality data platform based on big data technology. In the process quality data platform, all data related to process quality and process flow in the production process are put together to form a process quality data center. The process quality data platform is not simply to complete the acquisition and storage of data for analysis, but to restore the production process through data. [0003] At present, in Baosteel's quality management system, the effective determination of surface defects has played an important role in stabilizing production, reducing quality objections of surface defects, and finding and improving the causes of quali...
