What is a medium frequency heating system?

  Medium frequency heating system adopts IGBT power device and ZHENGZHOU KETCHAN’s fourth-generation variable current control technology based on parallel resonance. In this technology, the power, and frequency conversion control independently, IGBT switching device and amorphous inductor are adapted to form the high frequency chopper circuit to adjust power, using IGBT parallel resonant and frequency automatic tracking technology to obtain accurate soft switch control inverter process, makes the medium frequency heating system work reliability under high power is greatly increased, and improved the machine power level, makes the 100% equipment transient load rate is achieved.

What are the main componets of the medium frequency heating system?

  Medium frequency heating system series power supply all use the parallel resonant circuit, according to different application occasions, can choose direct output or output with intermediate frequency transformer, the basic structure, and composition areas the following two:

  This structure is most commonly used, such as medium-frequency forging furnace, medium-frequency melting furnace is all using this structure, simple equipment structure, low loss, high efficiency, and low manufacturing cost.

  Also, in this structure, the induction heating coil is relatively long, usually with a 3 – 10 meters long copper tube winding system.

  As the intermediate frequency power supply directly output, so the maximum voltage on the induction coil is 550V, and it is not isolated from the main power, so the induction coil must be well insulated, and can not be directly exposed to the air.

  This structure is also more commonly used, such as vacuum melting furnace, and intermediate frequency induction quenching. In this structure, by changing the ratio of the intermediate frequency transformer, different output voltage and induction coil current can be obtained to adapt to different requirements.

  In this structure, the induction coil is isolated from the main electricity, so the induction coil has good safety, and low insulation requirements and even the copper tube can be directly exposed. But due to the increase in the manufacturing cost of the medium frequency transformer, so the equipment cost is high, and the intermediate frequency transformer is larger, but also increased a certain amount of energy loss. The lower the frequency, the larger the medium frequency transformer, the higher cost, and the greater loss.
