［Application］
These demagnetizers produce an alternating magnetic field on the
surface by use of an AC power source, through which workpieces are
passed to remove the magnetism remaining on their surface.
［Features］
●Demagnetization is carried out by varying (sweeping) a frequency
lower than commercial frequencies from a lower point to a higher
point. This design has improved the demagnetizing performance
without increasing the amount of electricity to use.
●The demagnetizing section is of the same dimensions as the
conventional table type demagnetizer (KMD-C). With the same output
current (AC eff ective value) as the conventional model, the residual
magnetism in workpieces (SKH material) can be reduced to one third.
●Workpieces are demagnetized by passing them over the demagnetizing
surface at a constant speed, as with the conventional model.
●Continuous power on specification, but heat generated in the
demagnetizing part is less than the conventional model.
●A demagnetizing output variable resistor is provided on the electrical
unit that can vary the output current (AC eff ective value) in a range of
100% and 70%. This feature achieves demagnetization of low-carbon
steel like S45C by less power (70%) than the conventional model.
