Direct induction heating
It excludes Carbon completely from the melt. The eddy currents are generated in the metal directly. This concept demands certain soundness of the workpiece to allow its electromagnetic coupling with the induction coil (material, quantity, shape, position). However, in case of more or less sound metal in the crucible, it improves thermal efficiency of the process and allows melting of materials with higher melting point or affine to Carbon in a very efficient, economic and safe way.
Both concepts guarantee for the user the maximum efficiency and also flexibility, reduces the electrical consumption, increases the maximum temperature, increases heating speed and reduces the electromagnetic emission in terms of EMC.
