High quality induction heating machine 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.
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.

Here, I melt the first pieces of aluminum in my 1000W inductive furnace attachment with my graphite crucible. It works by pulsing the DC at a high frequency. This creates a constantly changing magnetic field that induces eddy currents in the graphite crucible. Graphite makes for a great susceptor because of it’s ability to absorb electromagnetic fields and convert them to heat. That’s why it’s used in many crisper sleeve for microwavable foods. A susceptor is a material that is used for its ability to absorb electromagnetic energy and convert it to heat. Here, I explain the material choices I made for my 1000W induction solder pot. I used a steel conduit coupler with a steel plug wrapped with aerogel infused fiberglass exhaust wrap. I made the working coil with litz wire and secured it in place with kapton tape. For an even better solder pot, you could use a graphite crucible like in the last step. In this next video, I show you how to use the solder pot. I feel it really demonstrates the usefulness of the solder pot.
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. In general, it will cost 300-350KW*H electric power to melt 1MT copper.
