Advantages and Work Principle of Medium Frequency Induction Heating Furnace

Medium frequency induction heating furnace is a power device that transforms AC electricity with a frequency of 50Hz to more than 300Hz to 20kHz. The three -phase work frequency AC power is turned into DC power after rectification. The mid-frequency interchange current flowing in the inductive coil generates high-density magnetic lines in the inductive ring, and cuts the metal material in the inductive ring, which produces a large vortex in the metal material. This vortex also has some properties of the intermediate frequency current, that is, the free electrons of the metal itself flow in the metal body with resistance to generate heat.

For example, put a metal cylindrical body in an inductive ring with an intercourse -changing current. The metal cylindrical body did not directly contact the inductive coil. And this kind of red and melting speed can be realized as long as the strength of the frequency and current.

If the cylindrical body is placed in the center of the coil, the temperature around the cylindrical body is the same, and the cylindrical heating and melting will not produce harmful gases and strong light pollution environment.

Medium frequency induction heating advantages:

● The heating speed is fast, and the oxidation and carbon are small. Due to the principle of heating in the medium frequency induction, the heat is electromagnetic, and its heat is generated in the work piece itself. Because the heating method is fast, the oxidation is very small, the heating efficiency is high, and the process is repetitive.

● The heating is uniform, the temperature control accuracy is high, the heating is easy to achieve uniform heating, and the temperature difference between the core watch is small. The application temperature control system can achieve precise control of temperature.

● Compared with other heating methods, low energy consumption and pollution -free induction heating, high heating efficiency, low energy consumption, and no pollution; various indicators can meet user requirements. Under heat permeability, the power consumption from room temperature to 1100 ° C is less than 360.
