Plate demagnetizer KMD-F

for workpiecesAC

[Application] This model is designed to generate an alternating magnetic field on the surface by an AC power source, where workpieces are passed to eliminate the magnetism remaining on the surface of workpieces. [Features] Demagnetization is carried out by varying (sweeping) a frequency lower than commercial frequencies from a lower point to a higher point. This model has improved the demagnetizing performance without increasing the amount of electricity to use. The demagnetizing part is of the same dimensions as the conventional table type demagnetizer (KMD-C). With the same output current (AC effective value) as conventional models, 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 conventional models. Continuous power on specification, but heat generated in the demagnetizing part is less than conventional models. A demagnetizing output variable resistor is provided on the electrical unit that can vary the output current (AC effective value) in a range of 100% and 70%. This feature achieves demagnetization of low-carbon steels like S45C by less power (70%) than conventional models.
