The difference between intermediate frequency aluminum melting furnace and intermediate frequency iron melting furnace

Aluminum is a non-magnetic material. During the entire smelting process, the magnetic field is very easy to diverge, so the yoke layout should be reasonable. First of all, the area of the yoke must be large enough and as long as possible to ensure that the axial and radial magnetic fields of the inductor have sufficient edges. If the inductor is a two-segment coil (parallel rewinding), the problem of magnetic flux leakage at the middle gap must be considered. Secondly, the distance between the turns of the sensor is not easy to be too large, and 8-12mm is appropriate.
