Higher Yield: The absence of combustion sources reduces oxidation losses that can be significant in production economics.
Faster Startup: Full power from the power supply is available, instantaneously, thus reducing the time to reach working temperature.
Flexibility: No molten metal is necessary to start medium-frequency coreless induction melting equipment. This facilitates repeated cold starting and frequent alloy changes.
Natural Stirring: Medium frequency units can give a strong stirring action resulting in a homogeneous melt.
Cleaner Melting: No by-products of combustion means a cleaner melting environment and no associated products of combustion pollution control systems.
Compact Installation: High melting rates can be obtained from small furnaces. A coreless furnace capable of melting 2,500 lbs./hr. of aluminum has a crucible measuring 3′ in diameter by 6′ in-depth.
Reduced Refractory: The compact size in relation to the melting rate means induction furnaces require much less refractory than fuel-fired units.
Better Working Environment: Induction furnaces are much quieter than gas furnaces, arc furnaces, or cupolas. No combustion gas is present and waste heat is minimized.
Energy Conservation: Overall energy efficiency in induction melting ranges from 55 to 75 percent, and is significantly better than combustion processes.
An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminium, and precious metals.

The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal melting. (induction melting furnace manufacturers in ahmedabad)
Most modern foundries use this type of furnace, and now also more iron foundries are replacing cupolas with induction furnaces to melt cast iron, as the former emit much dust and other pollutants.
Since no arc or combustion is used, the temperature of the material is no higher than required to melt it; this can prevent loss of valuable alloying elements.
The one major drawback to induction furnace usage in a foundry is the lack of refining capacity; charge materials must be clean of oxidation products and of a known composition and some alloying elements may be lost due to oxidation (and must be re-added to the melt).
In the coreless type, metal is placed in a crucible surrounded by a water-cooled alternating current solenoid coil. A channel-type induction furnace has a loop of molten metal, which forms a single-turn secondary winding through an iron core.

An induction furnace consists of a nonconductive crucible holding the charge of metal to be melted, surrounded by a coil of copper wire. A powerful alternating current flows through the wire. The coil creates a rapidly reversing magnetic field that penetrates the metal. The magnetic field induces eddy currents, circular electric currents, inside the metal, by electromagnetic induction.The eddy currents, flowing through the electrical resistance of the bulk metal, heat it by Joule heating. In ferromagnetic materials like iron, the material may also be heated by magnetic hysteresis, the reversal of the molecular magnetic dipoles in the metal. Once melted, the eddy currents cause vigorous stirring of the melt, assuring good mixing.
An advantage of induction heating is that the heat is generated within the furnace’s charge itself rather than applied by a burning fuel or other external heat source, which can be important in applications where contamination is an issue.
Operating frequencies range from utility frequency (50 or 60 Hz) to 400 kHz or higher, usually depending on the material being melted, the capacity (volume) of the furnace and the melting speed required. Generally, the smaller the volume of the melts, the higher the frequency of the furnace used; ( induction melting furnace manufacturers in ahmedabad)this is due to the skin depth which is a measure of the distance an alternating current can penetrate beneath the surface of a conductor. For the same conductivity, the higher frequencies have a shallow skin depth—that is less
An operating induction furnace usually emits a hum or whine (due to fluctuating magnetic forces and magnetostriction),( induction melting furnace manufacturers in ahmedabad) the pitch of which can be used by operators to identify whether the furnace is operating correctly or at what power level.
About Induction Melting Furnaces
