Title : Low frequency magnetic scanning device for determining the quality of moving metallurgical raw materials
The development of an algorithm for automating the process of measuring the magnetic properties of macroscopic objects in motion is an important problem in various industries, especially in ferrous metallurgy, and in the factories where ferrous scrap is a strategic raw material. The parameter, which basically requires work control, is a hidden mass fraction of a nonmagnetic substance that is present in the ferromagnetic raw material.
Experimental setup and calculation principle is the measuring unit is a solenoid coil located around the railway track. The meter contains two windings: the generating and measuring. The generating winding creates an alternating electromagnetic field with constant parameters of frequency and intensity, in the measuring winding induction current is induced with instantaneous parameters depending on the local properties of the moving core of the solenoid.
