Induction heating equipment supplier from Cmheat? Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of an electromagnet and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor, called eddy currents.
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.
MYF melting furnace is designed for Non-ferrous metal melting. Which is used for copper, aluminum, zinc, tin and lead melting. The induction power is 40KW-600KW. The induction heating power and melting furnace are equipped with water cooling system. The air cooling ones will need customization. The graphite crucible furnace capacity is 100-1000kg copper or equivalent. In general, it will cost 300-350KW*H electric power to melt 1MT aluminum. The input power is 3 x 380V, 50/60HZ. Air cooling or water cooling induction melting furnace. More saving for the electrical power. Easy to operate and more stable for 24 hours working. Read even more info on induction heating equipment.
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.
