GROW CONTROL Zone Refining system is used in materials processing to refine metals, especially to remove impurities and enhance the purity of materials. It uses induction heating to create a localized high-temperature zone where impurities can be separated from the base metal. The system uses electromagnetic induction to generate heat in the material. When an alternating current passes through a coil, it creates a magnetic field that induces eddy currents in the metal. These currents cause localized heating in the metal.

The temperature in the induction zone is high enough to melt specific areas of the material while leaving the rest solid, enabling a process where purity of material can be concentrated and removed from the molten zone
