Magnetic Spectral Analysis Method of Ferromagnetic Mixture

There are different magnetic property of materials mixed in the mechanical wear of abrasive and powder processing. Depending on different alloy and magnetized material with different magnetic saturation characteristics, some substances reach the magnetic saturation in the magnetization processing soon, while some substances must be in a strong magnetic field to reach saturation, resulting in the magnetic property of combination material mixed with multi-component metal abrasive has multi-ingredient combination characteristics. Based on the PQ excitation measurement method, we analyze the magnetic property between the typical magnetic abrasive individual and combinations. We also build the magnetic spectral characteristics of the mixture which is made up of materials with different magnetic property, and finish the establishment of two mixtures mapping. This paper aims to explore the magnetic spectral analysis method of ferromagnetic mixture from the theory and experiment, and propose the magnetic spectrum analysis and calculation method of the mixture.
