Process for acquiring and/or monitoring material properties of electrically conducting material used in rolling mills comprises using electromagnetic eddy current technique with eddy current excitation and detection

摘要

Acquiring and monitoring material properties of an electrically conducting material and parameters of bodies made from electrically conducting material comprises using an electromagnetic eddy current technique with eddy current excitation and detection. The eddy current excitation is produced in the material with different high frequencies of a prescribed frequency range. Preferred Features: A detector sensitive to a magnetic field is used in the process.
