What is Induction Melting？
Using an induction furnace with a non-contact heating technique, induction melting is the process of melting metal.
The method relies on the electromagnetic induction principle, in which a coil of copper wires is subjected to an alternating current (AC), which induces a magnetic field.
The metal then experiences eddy currents due to the magnetic field, which causes heat to be produced and causes the metal to melt.
Metals such as iron, steel, copper, brass, and aluminum among others are melted using this method.
It is frequently employed in commercial settings including foundries, steel mills, and metal fabrication plants.
