High quality induction heating machine manufacturer? 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 power size 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. The induction melting system consists induction heating power, melting furnace and graphite crucible.We can choose the right electric power and melting capacity upon the melting speed requirement. The standard heating power size and Crucible capacity is as following. Find additional info at induction heating equipment.
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.
