Premium 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.
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.

Here, I’ll show you an easy way to determine the carbon content of your steel parts by observing the spark profiles. You can use this technique to find which of your parts would benefit from the case hardening method used in my last video. This is not the most accurate way of determining the composition of the steel, but many welders use this technique when welding unknown materials and is a good test for most non-critical jobs. This technique is known as spark testing. Here, I make a pancake coil attachment and boil water in about 10 seconds. It works by pulsing the DC at a high frequency(about 160kHz). This creates a constantly changing magnetic field that induces eddy currents in the cast iron skillet. Induction heating is more efficient than many other methods because there is less wasted heat. For example, induction cooktops are more efficient than electric and gas stoves.
