Blister packaging high frequency power supply classification

According to the frequency of the alternating current, induction heating heat treatment can be divided into five categories: ultra-high frequency, high frequency, super audio frequency, medium frequency and power frequency.

① The current frequency used for UHF induction heating heat treatment is as high as 27 MHz, and the heating layer is extremely thin, only about 0.15 mm, which can be used for thin-layer surface quenching of workpieces with complex shapes such as circular saws.

②The current frequency used for high-frequency induction heating heat treatment is usually 200~300 kHz, and the depth of the heating layer is 0.5~2 mm, which can be used for surface quenching of gears, cylinder liners, cams, shafts and other parts.

③ The current frequency used in the ultrasonic induction heating heat treatment is generally 20~30 kHz. The small modulus gear is heated by the ultrasonic induction current, and the heating layer is roughly distributed along the tooth profile, and the performance is better after the fire.

④The current frequency used in the medium frequency induction heating heat treatment is generally 2.5~10 kHz, and the depth of the heating layer is 2~8 mm. It is mostly used for surface quenching of workpieces such as large-module gears, shafts with larger diameters and cold rolls.

⑤ The current frequency used for power frequency induction heating heat treatment is 50~60 Hz, and the depth of the heating layer is 10~15 mm, which can be used for surface quenching of large workpieces.
