60KW High Frequency Induction Melting Furnace
Rated Power Output:60KW
An induction melting furnace is an electrical furnace in which the heat is applied by induction heating of metal. Induction furnace capacities range from less than one kilogram to one hundred tons, and are used to melt iron and steel, copper, aluminum, and precious metals.
The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal melting.
Most modern foundries use this type of induction furnace, and now also more iron foundries are replacing cupolas with induction furnaces to melt cast iron, as the former emit lots of dust and other pollutants.
(1) Fast heating speed, high production efficiency, less oxidative decarburization, saving material and forging cost.
(2) Excellent working environment, improve workers’ working environment and company image, no pollution, low energy consumption
(3) Uniform heating, minimal temperature difference between core and high temperature control.

How the 60KW High Frequency Induction Melting Furnace Works
An induction melting furnace consists of a nonconductive crucible holding the charge of metal to be melted, surrounded by a coil of copper wire. A powerful alternating current flows through the wire. The coil creates a rapidly reversing magnetic field that penetrates the metal. The magnetic field induces eddy currents, circular electric currents, inside the metal, by electromagnetic induction. The eddy currents of induction furnace, flowing through the electrical resistance of the bulk metal, heat it by Joule heating. In ferromagnetic materials like iron, the material may also be heated by magnetic hysteresis of induction melting furnace, the reversal of the molecular magnetic dipoles in the metal. Once melted, the eddy currents cause vigorous stirring of the melt, assuring good mixing.

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.
What are typical utility requirements for induction?
Of course it depends on the system, but a typical typical system requires 380, 3-phase VAC at 50 Hz and 30 Amps. Also figure on 80 PSI compressed air and 40 PSI water at 4 gallons per minute for cooling.
Is this joint suitable for induction brazing?
Our team of metallurgical and mechanical engineers will be glad to have a look at your parts and process and give you our best advice – no obligation!
How can my process benefit from induction heating?
It can benefit your process in a number of ways. Induction heating is highly repetitive once making the initial adjustments to the power supply. Following this phase, it will heat part after part with identical results so long as introduces the parts to the coil similarly each cycle. This can also lead to better material utilization and product yield. Induction heating can reduce or eliminate the need for skilled operators in application such as brazing and soldering. The ability of induction heating to heat all parts identically lends itself to automation of the process. Induction heating can also heat the part in a highly localized fashion. It can be extremely beneficial when it is desirable or necessary to limit the heat to only a certain region of the part.
Can diamond bits be brazed with induction heating?
Sure, in fact induction heating is preferable for diamonds bits because it works so quickly. The longer the diamond remains at heating temperature, the faster it degrades. So we recommend atmospheric brazing in a vacuum atmosphere for the best results.
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.
