The invention relates to a flat steel crack detection method. The method includes the following steps of S1, rust removal; S2, surface filling; S3, red clay removal; S4, image acquisition; and S5, image processing. The method can quickly identify a crack point by transforming the identification of a crack on steel surface into the identification of a pixel point.
Description
technical field [0001] The invention relates to the field of flat steel manufacturing, in particular to a method for detecting cracks on the surface of flat steel. Background technique [0002] In the production process of special steel, it is generally made after heat treatment of ordinary steel. However, before ordinary steel is prepared, rust is usually attached to the surface of the steel, which makes it difficult to observe the surface of the steel, making it difficult to adhere to the cracks on the surface of the flat steel, which has a significant impact on later use. [0003] In view of the above-mentioned defects, the designer is actively researching and innovating, in order to create a new structure of flat steel crack detection method, so that it has more industrial application value. Contents of the invention [0004] In order to solve the above technical problems, the object of the present invention is to provide a method for detecting cracks in flat iron and...
