Do you know about the induction heating power supply of spring steel wire quenching and tempering production line?

Most spring steel wires are modulated. After quenching and tempering, the steel wires obtain high strength limits and high elastic limits. Therefore, the modulation heat treatment of spring steel wire has a very important impact on the quality of spring steel wire. Induction heating power supply is an important part of the spring steel wire induction heating quenching and tempering production line. Today, we will talk about some situations of induction heating power supply for spring steel wire quenching and tempering production line.

Steel wire quenching and tempering are heated by dual-frequency power supply. The maximum quenching heating temperature is 950~980°C. Below the Curie point 723°C, a medium frequency thyristor power supply with a frequency of 4~6kHz is used for heating. Above the Curie point, a 30kHz IGBT super audio power supply is used for heating. Dual-frequency heating can obtain relatively high heating. efficiency. The maximum heating temperature for tempering heating is 650°C, and a medium frequency thyristor power supply with a frequency of 4 to 6 kHz is used for heating. The power supply adopts voltage and current double closed-loop control, with internal and external bidirectional control functions. Internal control can be done manually, and external control can be controlled by PLC. Today we will take a look at the configuration of the inductor of the steel wire induction heating production line with a diameter of 8-10mm.
