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 steel coil surface defect determination method based on the surface defect distribution characteristics, which comprises the following steps: Step 1, determining the data range; Step 2, filtering noise data; Step 3, standardizing the defect position of the steel coil: The coordinates on the steel coil are converted to between 0 and 1, and the length and width of the steel coil are standardized to 1, etc. The present invention utilizes rules to complete the quantitative description of steel coil surface defects based on distribution characteristics, adds a new analysis perspective for surface defect analysis, and completes defect classification based on surface defect distribution characteristics; defect analysis in multiple batches and across units It provides data support for technical experts in the process of tracing back the cause of defects, thereby improving the efficiency of surface defect determination and reducing the impact of human factors on defect determination.

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...
