What is induction melting? Induction melting is the induction heating of a metal, typically within a crucible until the metal becomes molten using an induction furnace. Once the metal has fully melted, the liquid is then poured into an ingot mold or cast into a component at a foundry, or into smaller precise parts such as dental and jewelry castings. How does induction melting system work? An Induction melting furnace uses a copper induction heating coil that delivers an alternating magnetic current to the metal within the coil. This alternating magnetic current creates a resistance in the metal, causing it to heat and eventually to melt. Induction furnace technology does not require any flame or gasses that can be harmful to the environment to melt metals.

Induction heating is the process of heating the materials which are electrically conductive by electromagnetic induction like metals. Working Principle of Induction Heating: Induction heating makes use of the induced current by the electromagnetic induction in the charge to be heated. The induction heating works on the principle of transformer action, in which the primary winding which is supplied from an AC source is magnetically coupled to the charge, to be heated, which acts as a short-circuited secondary of a single turn.
Now the principle of Joule heating is observed. According to this when a current is passed through a material heat is generated in the material. So, when current is generated in the material due to the induced magnetic field, the flowing current produces heat from within the material. This explains the process of non-contact inductive heating. The setup used for the induction heating process consists of an RF power supply to provide the alternating current to the circuit. A copper coil is used as inductor and current is applied to it. The material to be heated is placed inside the copper coil. Targeted heating for surface heating, melting, soldering is possible with the inductive heating process. Besides metals, heating of liquid conductors and gaseous conductors is possible by inductive heating. For heating of silicon in semiconductor industries, the inductive heating principle is used.
