The Working Principle of Medium Frequency Induction Melting Furnace

 

Medium Frequency induction furnace is mainly composed of a power source, an induction coil and a crucible made of refractory material inside the induction coil. The crucible contains metal charging, which is equivalent to the secondary winding of the transformer.

 

When the induction coil is connected to the AC power source, an alternating magnetic field is generated in the induction coil, and the magnetic flux cuts the metal charging in the crucible. Then an induced electromotive force is generated in the furnace. Since the charging itself forms a closed loop, the secondary winding is characterized by only one turn and is closed. Therefore, an induced current is simultaneously generated in the charging, and when the induced current passes through the charging, the charging is heated to cause it to melt.

 

It is heating metal by electromagnetic induction principle.

How exactly does induction hardening furance work?

In a basic induction heating setup, a solid state radio frequency power supply sends an AC current through an inductor (often a copper coil), and the part needs to be heated (the work piece) will be placed inside the inductor. The inductor serves as the transformer primary, and then the part needs to be heated therefore becomes a short circuit secondary. When a metal part is placed within the inductor and enters into the magnetic field, inside the part, the circulating eddy currents will be induced. These eddy currents generate precise and localized heat without any direct contact between the part and the inductor.

 

In the process of induction heating the material, there is therefore no contact between the inductor and the part, and neither are there any combustion gases. The material needs to be heated can be located in a setting isolated from the power supply, that is to say, it can be submerged in a liquid, covered by isolated substances, in gaseous atmospheres or even in a vacuum.

What is induction heating?

The heating method known as induction heating occurs when we please an electrically conductive material in a varying magnetic field. So induction heating is a rapid form of heating. Its current is induced directly into the heated par. Also, induction heating is a non-contact form of heating.

 

Can you braze glass or ceramics with induction?

If you work with glass or ceramics, a compact vacuum furnace is a great solution for brazing. You’ll get quick, clean heat with very precise temperature control.

 

What makes up a typical induction heating system?

A typical induction heating system consists of the induction heating power supply, an induction heating coil and a water-cooling source and several internal components inside the power supply. The induction heating power supply sends alternating current through the induction coil, thus generating a magnetic field. Hence place a work piece within the coil and enters the magnetic field, then it induces eddy currents within the workpiece. Furtherly it’s generating precise and localized heat without any physical contact between the induction coil and the work piece.

 

 

Will induction heating increase my utility bills?

Not likely. Induction heating is a very effective, efficient means of heating. Most of our customers who are switching to induction for the first time see their utility bills go down.

 

When is it better to use the indirect heat of an induction furnace instead of direct induction heat?

Yeah, we get that question a lot. It depends on the geometry of your part and how you want to heat it. If you have a part with simple geometry and your process calls for heating a specific area of the partg. We suggest that direct induction heating will generally be preferable. However, if you need to heat the entire part, or if the part has a complex shape. Then you’ll achieve better results with an induction heating vacuum furnace.
