High quality induction heating machine supplier

Induction furnace manufacturer by cmheat.com? An important feature of the induction heating process is that the heat is generated inside the object itself, instead of by an external heat source via heat conduction. Thus objects can be heated very rapidly. In addition there need not be any external contact, which can be important where contamination is an issue. Induction heating is used in many industrial processes, such as heat treatment in metallurgy, Czochralski crystal growth and zone refining used in the semiconductor industry, and to melt refractory metals that require very high temperatures. It is also used in induction cook-tops for heating containers of food; this is called induction cooking.

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.

A torch is commonly used when you can’t loosen a seized nut or bolt. By heating the nut with the induction heater, the metal will expand and you can free the seized hardware. Using a torch is dangerous in confined areas and using flameless heat prevents damage to the surrounding parts such as, wire harnesses, fuel lines, anything plastic, anything volatile and flammable. Induction heaters are often used by aircraft mechanics when using a flame would be a bad idea. Here, you can see that the coil is levitating the aluminum. The works because of Lenz’s law. This means that when it is introduced to a constantly changing magnetic field, the induced currents in the aluminum create an opposing field to that of the coil. This is the same thing that is happening when you drop a strong magnet down a copper pipe. The magnet is slowed down due to the opposing field that the copper is producing.
