In modern industrial manufacturing, eddy current testing technology has become an important tool for ensuring the surface quality of forged steel rolls. Eddy current roll surface detection is based on...
The rolling element has a large surface contact stress during operation, so the quality of the rolling element has an important influence on the life and performance of the bearing.
Magnetic flux leakage detection(MFL)means that after the ferromagnetic material is magnetized, a leakage magnetic field is formed on the inner and outer surfaces due to defects of the iron pipe.
