Everyone is saying that the intermediate frequency furnace is an induction heating equipment, or the mainstream induction heating equipment in the mechanical thermal industry. It is used as the heating before forging in the forging industry, and is called the intermediate frequency heating furnace; In the casting industry, it is used for metal melting, which is called medium frequency smelting furnace; In the metal heat treatment industry, it is used for metal quenching and tempering heating, which is called medium frequency quenching and tempering heating furnace. All these are from the perspective of use, so what is the heating principle of the intermediate frequency furnace? What is an intermediate frequency furnace? How should I buy an intermediate frequency furnace? Luoyang Shennai came to popularize the knowledge of intermediate frequency furnace.

From the perspective of the heating source of the intermediate frequency furnace, the intermediate frequency furnace is a frequency conversion device, which converts 50HZ alternating current into medium frequency (above 100Hz to 8000Hz) silicon controlled variable frequency power supply device. The intermediate frequency power supply device of the intermediate frequency furnace filters and rectifies three-phase alternating current into DC, and then converts these direct current into adjustable intermediate frequency current to supply the load composed of capacitor and induction coil. When the intermediate frequency current passes through the induction coil, It will generate magnetic lines of force and cut the metal materials in the induction coil, which will generate a large eddy current in the metal materials. Vortex flow in the heated metal will generate heat, so that the metal is heated. This is the basic principle of medium frequency furnace heating.

Of course, the medium frequency furnace heating still needs a lot of specific details to match. For example, the electromagnetic ring effect, the electromagnetic sharp corner effect, the electromagnetic skin effect, the frequency selection of the intermediate frequency furnace, the determination of the heating power of the intermediate frequency furnace, the determination of the heating time of the intermediate frequency furnace, the selection of the intermediate frequency reactor, the determination of the capacitor bank of the intermediate frequency furnace, and the selection of the silicon controlled rectifier of the intermediate frequency furnace. In general, the intermediate frequency furnace is a non-standard induction heating equipment, The induction heating equipment of intermediate frequency furnace is customized according to the specific conditions required by customers.

Luoyang Shennai believes that the order of purchase of intermediate frequency furnace should be considered emphatically is as follows:

1. First of all, what is the use of the intermediate frequency furnace, metal heating? Is it quenching and tempering heat treatment? Or metal smelting?

2. Secondly, what is the material of the metal to be heated by the intermediate frequency furnace, steel? Iron? aluminium Copper? stainless steel? Alloy steel?

3. Determine the heating temperature of intermediate frequency furnace again? Annealing temperature? Quenching temperature? Forging temperature? Or melting temperature?

4. Then determine the weight of the metal to be heated, that is, how much metal to be heated by an intermediate frequency furnace.

5. After determining the heating power of the intermediate frequency furnace, the intermediate frequency power supply of the intermediate frequency furnace and the inductor coil of the intermediate frequency furnace can be configured.

6. Design auxiliary facilities of intermediate frequency furnace, such as feeding mechanism, discharging mechanism, three sorting mechanism and temperature measuring device of intermediate frequency heating furnace; Feeding trolley, remote monitoring and other auxiliary equipment of smelting furnace.

The above is the use, principle and purchasing knowledge of intermediate frequency furnace. If you still don't understand, please consult Luoyang Shennai.
