Understanding Induction and Induction Furnace

by Robert P.

During induction, metal is transformed into a cherry red color in split seconds. For people who are not acquainted with induction heating, this process can be a bit surprising. Smaller companies make use of Small induction furnace to complete this process and vice versa.

Before purchasing an induction tool, you must ensure that it’s capable of understanding electromagnetism, process control, physics, and power electronics. Induction furnaces yes for induction heating are usually from below one kg to one hundred tons (t) and can breakdown iron, steel, aluminum, copper, and other kinds of metal. Here, in this piece, you will find out more of the things you should know about induction heating.

Induction Heating

Induction heating is the system of heating objects conducted by electricity through the use of electromagnetic induction. The object generated heat through eddy currents and this is also used to finish up the induction heating procedures.

Further, the induction heater contains an electronic and electromagnetic oscillator that goes through an alternating high-frequency current by an electromagnet.

Irrespective of the batch size, induction heating has definite controllability, unlike most combustion techniques. It’s an ideal way of handling tempering, hardening, annealing, case hardening, and other types of heat treatment.

However, if more important applications such as aerospace, automotive, ammunition bonding, tempering of spring wire, fiber optics, wire hardening, etc., a higher level of accuracy is needed.

Lastly, for specific metal applications that involve precious metals, titanium, and enhanced components, you must consider induction heating a necessity. This is because of the unmatched exactness if it’s heating control.

Materials needed for induction heating

Two main materials should be used to start and end an induction heating process; they are:

  • A material that can easily be conducted with electricity. It should be fixed into a magnetic field.
  • A magnetic field that can be switched.

The Importance of Induction Furnaces

No matter the kind of metal you deal on, you stand to gain a host of benefits from induction furnace than any other kind of furnace. Let’s have a look at some of them below:

  1. They are great options for melting metals like silver, gold, brass, copper, zinc, aluminum, silicon, etc. These composites, when melted, can be used for industrial purposes.
  2. They do not occupy a lot of space. This makes it great for different sizes of a foundry.
  3. Induction furnaces are more eco-friendly, unlike some other types of furnaces.

They are highly efficient (energy wise). This means that they won’t cause any negative effect when used for production in a company.

  1. When it comes to production, you can use an induction furnace to reduce your environmental footprint.
  2. They are also great alternatives for ensuring productivity in a company as they make automation easier.


An induction furnace is the best way to handle your foundry. After going through the different aforementioned benefits, you’d be able to figure out if it’s a wise decision to use induction heating for melting metals in your business. It saves space, energy, and prevents loss.
