Induction melting furnaces are electrical furnaces that use induction heating to melt metals like iron, steel, copper, aluminum, and precious metals.
These furnaces are known for their cleanliness, energy efficiency, and precise control.
They can reach temperatures up to 2800°C.
The design of induction melting furnaces varies.
Common types include coreless, channel, and crucible furnaces.
Each type differs in size, capacity, frequency, and specific design features.
7 Key Components Explained
1. Power Supply
The furnace operates through an induction coil connected to an AC power supply.
This connection generates an alternating magnetic field within the coil.
2. Induction Coil
The induction coil is the primary component where the magnetic field is generated.
The coil is designed to create a magnetic field that interacts with the metal charge in the crucible.
3. Crucible
The crucible is made from refractory materials and holds the metal charge.
It is positioned within the induction coil and acts as the secondary winding of a transformer.
4. Working Principle
When the induction coil is energized, it creates an alternating magnetic field.
This magnetic field induces an electromotive force in the metal charge within the crucible.
The metal charge forms a closed circuit, generating an induction current within the metal itself.
This current, known as eddy currents, heats the metal through resistance, leading to its melting.
5. Coreless Furnaces
Coreless furnaces use a water-cooled copper coil to generate the magnetic field.
They do not have a ferromagnetic core.
The molten metal forms the core, allowing for rapid melting and good temperature control.
6. Channel Furnaces
Channel furnaces, also known as channel-type induction furnaces, use a continuous loop of molten metal as the conductive path for the induction current.
They are suitable for continuous melting and holding applications.
7. Advantages and Limitations
Induction melting furnaces are highly efficient and can handle a wide range of metal types and sizes.
They are particularly useful for alloying metals with minimal losses.
However, these furnaces are less effective for refining metals, as they primarily focus on melting and alloying.
