High quality induction furnace supplier? The eddy currents flowing through the resistance of the material heat it by Joule heating. In ferromagnetic (and ferrimagnetic) materials like iron, heat may also be generated by magnetic hysteresis losses. The frequency of current used depends on the object size, material type, coupling (between the work coil and the object to be heated) and the penetration depth.
It’s a common misconception that induction heaters don’t work for aluminum and other non-ferrous metals. This is not true. This induction heater will heat up aluminum and copper just fine, but not as fast as ferrous metals. This is mainly due to their lower resistivity. The higher the resistivity of the conductive material, the more it generates heat when current is passed through it. The higher resistivity of most ferrous metals coupled with the heating due to hysteresis makes them ideal for induction heating, but they are not the only metals affected by induction.
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.
