Problems solved by technology
[0002] With the rapid development of my country's economy, the demand for steel in real estate, machinery manufacturing and other industries is also increasing. Among them, H-shaped steel is an economical and efficient section with more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named the same as the English letter "H"; because all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has excellent bending resistance in all directions, and it has the advantages of simple structure, light weight and convenient construction. , has been widely used; in the production process of H-shaped steel, its detection is an indispensable part. At present, the detection of H-shaped steel is carried out after the H-shaped steel leaves the production line and is cooled. This method is difficult to detect. , and it takes a lot of time to wait for the H-beam to cool itself, which seriously limits the production efficiency; therefore, a device for online detection of H-beam surface defects is needed
