Selecting the best induction melting furnace according to your industrial need could be a real challenge, this is because of the fact that there is a range of furnaces that are used for various industrial applications. An induction furnace is mainly a type of electrical furnace in which heating is done by the induction of electric current without having any direct contact with the induction oil but directly by the charge of itself that is produced by the induction in form of the electric current Thus heat is produced as a result which heats the furnace making it like a chamber.
An induction furnace is comprise of a hollow copper tube. That had been cooled by the water and then it is arranged in different shapes according to the need, most of the time the cylindrical-shaped copper coil is used in the industries that often require melting.
Its Working
This copper can produce an alternating current that is pass at a very high frequency. Due to which a strong magnetic field in produce around that area. And as soon as a conductor is pass from that area a huge magnetic influx is create inducing a circular current that is generate within the charge. As the induction generator consists of two coils that are known as a primary coil and a secondary coil. Primary coils are known for taking current at high voltage, low current, and a fixed frequency. Whereas the secondary oils convert this current into a low voltage, high current, and high frequency. This current and voltage is then transfer to the coil of copper.
How does it heat by the help in induction?
There are mainly two factors through which the process of heat is occurring these processes are
- Current Heating:
As the process of heat occurs, it induces electric current due to the resistivity of charge.
- Hysteric Heating:
Heat, in the form of energy, is produce within the charge by the alternating magnetic field. That had been generated by the coil that modifies the magnetic polarity of the charge.
However, this heats up only up to the optimum temperature thus the loss that occurs is only limited to the magnetic material, however, being heated beyond this temperature can lead to permanent deformation in a way of making it lose its magnetic properties thus making the hysteric heating as zero. However, the frequency also plays a major role in the process of heating because although not directly but the frequency can determine the depth up to which the induced current can reach the depth.
Uses of Induction Furnaces:
Induction Melting Furnace suppliers suggest various important uses of the induction furnaces, some of which are:
- The small-sized furnaces are ideal for melting small quantities for experimental purposes in labs.
- Manufacturing object that requires melting of metals.
- Jewelry manufacturing.
- Heat treatment industries in which heat is desire according to the need of the customers.
- In the heat treatment industries that requires melting of metals in huge quantities.
- Industries that require cleaner operations.
- Furnaces that can easily operate continuously.
