Electric Induction Furnace is a furnace where heat is
applied by induction heating of a conductive medium (usually a metal) in
a crucible around which water-cooled magnetic coils are wound.
The use of induction furnaces incur certain benefits. As compared to
other furnaces the operation of these furnaces are clean,
energy-efficient and well-controllable melting process. These types of
furnaces are mostly used in the foundries. Most modern foundries use
these type of furnaces for melting cast iron. The use of this type of
electric furnace reduces the emission of dusts and other pollutants.
Electric Induction furnaces are available in different capacities and
are used for melting iron and steel, copper, aluminum, and precious
metals.
Configuration
The electrical induction furnace consist of coiled metal structure in
the middle of the refractory through which alternating current is passed
thereby creating a magnetic field. The current is induced by the
magnetic field on the metal surface and heat throughout the refractory.
Features
Following are the features of induction furnace:
- The chemical durability is very high.
- The loss of alloy is low during the melting process
- The output has good quality with no impurities.
- Refractoriness is also very high.
- Comes in various sizes.
- Available in different capacities.
Applications
The electric induction furnace are used in various industries like iron
industry, aluminum industry, copper industry, etc. for various purposes
like
- Soldering
- Melting
- Stainless Steel
- Iron Casting
- Curing
- Drying
- Brazing
- Annealing
- Hardening
