High quality pwht 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.
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’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.
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.
