Induction Furnaces
Induction furnaces are useful to the manufacturing process. Used mainly in foundries, induction furnaces can be used in die casting as well. They consist of a refectory lined structure made of copper tubing with high conductivity. This tubing is cooled with cool water in which electrical currents alternate. The current generates a magnetic field that induce a current on the surface of the metal. This heat then melts the material. The heat is then carried away from the metal by refectory lining. The heat generated by the magnetic field and the power input inside the induction coil is cooled by a water cooled coil that is wound into a helical coil. The water cooled coil is cooled by a cooling tower. The cooling tower receives it water from a cooling pool that is located outside. This system is used day in and day out, in a continuous cycle.
Electric induction furnaces are used in the melting of ferrous and nonferrous applications. Two types of inductions furnaces exist. One is called core less induction and the other is called channel induction furnace. A core less induction furnace consists of a water cooled coiled made of copper tubing, a crucible installed within the coil and supporting shell. A channel induction furnace uses an induction unit held at the bottom of the shell. These furnaces are used in the production of steel, plastic and glass. These furnaces have many benefits. The system does not require the use of slag. Slag is run off material from metal that is normally glass like. Induction furnaces also and easy to control and require little set up. Induction furnaces are useful to manufacturing industries across the globe.
