Induction heating equipment supplier from Cmheat? 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.
The three main components of the machine are the power supply, the ZVS driver, and the working coil. The ZVS driver,(Zero Voltage Switching) was invented by Vladmiro Mazilli. It uses resonant zero voltage switching (also know as ZVS) to pulse the power supply very rapidly. This means the MOSFET’s are designed to switch (on or off) when the voltage across them becomes zero. Since the MOSFET’s switch when there is no voltage across them, they generate very little heat. The main source of heat is caused by the MOSFET’s internal resistance and the capacitors constantly charging and discharging. The circuit is fairly simple consists of just two MOSFETs, 6 capacitors, and a few resistors and diodes. You can build the circuit yourself, but it is cheaper to buy a premade board.
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.

Induction is particularly good at case hardening. This is because of the skin effect discussed in the next step. The same high frequency skin depth that is seen in the working coil is also seen in the part being heated. The higher the frequency, the more the current is flowing on the outside of the material. For steel in this case, the current is only flowing about 6 thousandths of an inch deep. This is perfect for case hardening. This process should only be used with low carbon steel so I’ll show you a way to determine what type of steel you have.
