Induction starts with a coil of conductive material (for example, copper). As current flows through the coil, a magnetic field in and around the coil is produced. The ability of the magnetic field to do work depends on the coil design as well as the amount of current flowing through the coil.
In the induction furnace, a coil carrying alternating electric current surrounds the container or chamber of metal. Eddy currents are induced in the metal (charge), the circulation of these currents producing extremely high temperatures for melting the metals and for making alloys of exact composition.
Hasung supplies a wide range of Induction Melting Systems and high frequency smelting equipment from 5.0kW to 200kW in power. The use of energy efficient induction heating for melting, replaces traditional gas-fired systems, thus reducing greenhouse gas emissions with clean energy.
HOW DOES INDUCTION MELTING 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.
