Premium induction furnace manufacturer? An important feature of the induction heating process is that the heat is generated inside the object itself, instead of by an external heat source via heat conduction. Thus objects can be heated very rapidly. In addition there need not be any external contact, which can be important where contamination is an issue. Induction heating is used in many industrial processes, such as heat treatment in metallurgy, Czochralski crystal growth and zone refining used in the semiconductor industry, and to melt refractory metals that require very high temperatures. It is also used in induction cook-tops for heating containers of food; this is called induction cooking.

Assembly is as simple as connecting the +terminal of your power supply to the +terminal of the ZVS driver and the -terminal of your power supply to the -terminal of the ZVS driver. The polarity of the working coil does not matter. I recommend an adjustable power supply and using a power meter to give you better control on your heat output. This induction heater works by pulsing the DC at a high frequency(about 160kHz). This creates a constantly changing magnetic field that induces eddy currents in conductive materials near the coil. Ferromagnetic materials will also heat up due to hysteresis. This is the heat produced from rapidly changing magnetic fields in the material. Induction heating is more efficient than many other methods because there is less wasted heat. For example, induction cooktops are more efficient than electric and gas stoves. I’ll be making more attachments and demonstrating more practical uses for inductive heat.

IGBT small induction melting furnace for steel, copper, brass, aluminum, gold melting, The melting power is from 15KW ~ 160KW. The melting capacity is from 2 kg ~ 150 kg. 1. MF melting furnace can be used for the melting of steel, stainless steel, brass,cooper, gold and so on. 2. Because of the stirring effect which caused by the magnetic force, the melting pool can be stirred during the melting course to ease the floating of the flux and oxides to produce high quantity casting parts. 3. Wide frequency range from 1KHZ to 20 KHZ, working frequency can be designed by changing the coil and compensating capacitor according to the melting material, quantity, stirring effect desire, working noise, melting efficiency and other factors.

The use of my wire choice is quite important here. I used what is known as Litz wire. Litz wire consists of many individually insulated wires. It is the preferred wire for use in high frequency application due to the skin effect. The skin effect is the tendency of current to flow on the outside of a conductor at high frequencies. The higher the frequency, the shallower the skin depth will be. Using Litz wire will result in much more efficient working coils for your system. Not only does it transfer the energy more efficiently, it also generates less heat of its own. If you have 10amps flowing through 260 strand Litz wire, that’s only 38mA of current in each wire. 10amps through a single conductor will generate substantial heat depending on the size. If you do not want to use Litz wire, the next best thing is copper tubing. It has more surface area for the current to flow so it is more efficient than an equivalently sized solid core wire.
