Electric Tilting Induction Melting Furnace

What is an electric induction furnace?

Induction melting furnace working video

An Electric Tilting Induction Melting Furnace is a type of furnace that uses electromagnetic induction to heat and melt metals. The furnace can be tilted to pour the molten metal into a mold or a container.?It is often used for melting gold, silver, steel, and other metals.

Some features of Electric Tilting Induction Melting Furnaces are:

• They have high electrical efficiency and low energy consumption.
• They have precise temperature control and fast melting speed.
• They have digital control panels with status messages and diagnostics features.
• They are easy to install, maintain, and service.
• They are compatible with different types of crucibles, such as ceramic, graphite, or silicon carbide.

How does an induction melting furnace work?

Electromagnetic induction generates electric currents in a conductor by exposing it to a changing magnetic field. The electric currents, also called eddy currents, flow through the material's resistance and heat it by Joule heating.?This is how metals are melted in an induction furnace.

The frequency of the alternating current that creates the magnetic field depends on the size and type of the metal.?Higher frequencies are used for smaller or thinner metals, while lower frequencies are used for larger or thicker metals.

The induction furnace can also use a core, such as an iron rod, inside the coil to increase the heating effect.?The core also generates heat by magnetic hysteresis losses, which is the energy dissipated when the magnetic domains of the material are repeatedly aligned and realigned by the magnetic field.

What is the difference between an electric furnace and an induction furnace?

The difference between electric furnaces and induction furnaces is mainly in their heating methods, energy consumption, and application areas.

• Heating methods: An electric furnace uses an electric arc or combustion to heat the metal, while an induction furnace uses electromagnetic induction to directly heat the metal.
• Energy consumption: An induction furnace has higher energy efficiency and lower energy consumption than an electric furnace, as the heat is generated within the metal and there is minimal heat loss.
• Application areas: An electric furnace is primarily used for melting and refining steel and cast iron in large-scale production facilities. In contrast, an induction furnace is commonly used for melting non-ferrous metals and small-scale operations.

What are the two types of induction furnaces?

The two types of induction furnace are?coreless?and?channel

·???A coreless induction furnace has a?crucible?surrounded by a water-cooled?coil?that creates a?magnetic field?to heat the metal inside.

·???A channel induction furnace has a?loop?of molten metal that forms a?single-turn secondary winding?through an?iron core.

Both types of induction furnaces use?electromagnetic induction?to directly heat the metal, without any combustion or electric arc.

What are the advantages of an induction furnace?

Some advantages of induction furnace are:?

·?It is a?clean,?energy-efficient,?and?well-controlled?melting process, compared to most other means of metal melting.

·? It does not require an arc or combustion, which can prevent the loss of valuable alloying elements and reduce the risk of contamination.

·?It has?precise temperature control?and?fast melting speed.

·?It has?digital control panels?with status messages and diagnostics features.

·?It is?easy to install, maintain, and service.

·??It is compatible with different types of crucibles, such as ceramic, graphite, or silicon carbide.

·?It can create a?homogeneous mixture?of the liquid metals by electromagnetic stirring.
