Description

Technical Field

[0001] The present invention relates to the technical field of scratch detection, and more specifically, to a detection device for surface scratches of continuous casting slabs. Background Art

[0002] Based on this, in the steel metallurgy and metal processing industries, continuous casting slabs, as key raw materials for subsequent processes such as rolling and forging, their surface quality directly affects the performance and qualification rate of the final products. Surface scratches are one of the common defects in the production process of continuous casting slabs. If not detected and processed in time, it will not only lead to an increase in material loss in subsequent processing operations, but may also cause serious problems such as product fracture and deformation due to stress concentration, causing huge economic losses to enterprises and at the same time affecting the competitiveness of products in the market. Therefore, efficient and accurate detection of surface scratches on continuous casting slabs is an important link to ensure production quality and improve production efficiency.

[0003] Currently, the traditional detection of surface scratches on continuous casting slabs mostly relies on manual visual inspection. This method not only has a high labor intensity and low detection efficiency, but is also easily affected by factors such as the experience, responsibility of the detection personnel and environmental light, and is extremely prone to missed detection and false detection, making it difficult to meet the requirements for detection accuracy and speed in modern industrial production. Although some enterprises have introduced detection equipment based on machine vision, the existing equipment generally has problems such as limited detection range, poor adaptability to complex lighting environments, and the detection head is easily affected by dust pollution and affects the accuracy. At the same time, it lacks the ability of intelligent analysis and linkage control of detection results and cannot achieve efficient coordination between detection and production processes.
