Common Detection Methods of High Speed Steel Roll
High-speed steel rolls have good wear resistance and thermal crack resistance, but they are sensitive to cracks caused by cooling, improper use or mechanical damage. Surface crack is the main reason of high speed steel roll failure. Generally, the surface of high-speed steel rolls is prone to mechanical cracks, network "hot" cracks, stress cracks and fatigue cracks. All manufacturers generally adopt good non-destructive testing methods and procedures to regularly inspect the rolls, and repair and replace the high-speed steel rolls with problems in advance to avoid rolling accidents. So, let's take a look at the common detection methods of high speed steel rolls. Commonly used high-speed steel roll detection methods are: 1. eddy current automatic flaw detection advantages: belonging to automatic flaw detection, with automatic recording system, can accurately determine the axial position of defects on the roll. The detection sensitivity is high, and some small surface or near surface defects can be found, which is unmatched by other detection methods such as ultrasonic. Disadvantages: The type, shape and depth of the crack cannot be determined, and the true equivalent of the defect cannot be determined. Sometimes it is affected by many factors, such as the distance between the probe coil and the measured reel, the material, size, shape, conductivity, magnetic permeability, defect type, etc. of the reel. Periodic calibration of eddy current sensitivity and other flaw detection
