In the steel industry, high speed steel rolls are key production tools. However, do you know how to ensure the quality and performance of these rolls? Today, we will reveal the mystery of the common detection methods of high speed steel rolls for you!
First, visual detection
- By observing the surface of the roll with the naked eye, check whether there are cracks, wear, corrosion and other defects.
Second, non-destructive testing
- Ultrasonic detection: The use of ultrasonic flaw detector to detect the internal defects of the roll.
- Magnetic particle detection: suitable for detecting cracks on the surface and near the surface of the roll.
- Eddy current testing: used to detect the defects and hardness distribution on the roll surface.
Third, hardness testing
- The hardness of the roll is measured to determine its wear resistance and deformation resistance.
Four，Metallographic analysis
- The metallographic structure of the roll was observed, and its material and heat treatment quality were analyzed.
Five，Size detection
- Check roll diameter, length, aperture and other dimensions to ensure compliance with design requirements.
End:
- The inspection of high-speed steel rolls is very important to ensure the quality and efficiency of steel production. Choosing the right detection method, finding the problem in time and repairing or replacing it can ensure the normal operation of the roll.
