Scope of application

It is mainly suitable for annealing of steel pipe joints, metal smelting, diathermy, hot forging, heat preservation, metal quenching, annealing, normalizing, tempering and other heat treatment processes.

Second, the technical characteristics

1. Two design modes of integrated machine and split machine can be adopted according to user needs.

2. The power factor of the power grid side is greater than or equal to 0.92; for high-power power supplies, 12-pulse thyristor rectification is used, the DC voltage is high, and the harmonic current on the grid side is small.

3. The inverter bridge adopts high-power, high-voltage KK type fast thyristor, with large design margin and stable and reliable operation.

4. The resonant inverter adopts digital control system, automatic angle setting, high phase-locking precision, wide phase-locking range and high start-up success rate.

5. The airtight chassis design meets the harsh environment requirements of the user's site.

6. The form of the resonance tank circuit is independently designed according to the actual needs of the user, and the on-site layout is convenient and flexible.

7. The three-phase rectification is controlled by a single-chip microcomputer, with precise triggering and small harmonics.

8. It has various protection functions such as overvoltage, overcurrent, water pressure, overclocking, etc., with reliable operation and low failure rate.

Equipment Configuration

KGPS series intermediate frequency induction heating equipment adopts thyristor (thyristor) as the key device of the inverter, and the single-chip microcomputer as the core constitutes an intelligent control system for rectification and inverter. It has the advantages of high efficiency, simple and reliable circuit, convenient debugging and operation, etc. It can not only improve the production process and product quality for production enterprises, but also have a significant energy saving effect.

It is composed of power cabinet, tank cabinet, circulating soft water cooling system, sensor, operating table and adjusting bracket.
