Quenching process flow

Using 250KW IGBT digital intelligent DSP induction heating power supply, frequency 5-20khz. 

Double pipe quenching 250kW Induction heating power output is used to quench the inner wall, and the inner water spray is used to quench the inner wall.

According to the process demand, DSP power supply can be used for digital power distribution.

When the induction heating equipment is heating the pump pipe of different specifications, the output power of inductor can be set automatically according to the model of the workpiece and the control system of the machine tool.

The central control center has a variety of heating process implementation and automatic control program switching functions.

No manual intervention is needed to switch between different quenching processes.The induction quenching heating coil is equipped with a water spraying device.

Through the centralized control center program switching, the water spraying cooling process is implemented automatically for different workpiece models

The running speed of the straight pipe of the production line is controlled by a fast high-power servo motor.

The designed air running speed is ≥3 m /min. When heating, the rotating speed is controlled by frequency conversion motor, supported by multistage supporting roller in the middle of straight pipe, which can meet the requirements of working procedure (including feeding and unloading) : 6min/ pc (3 meters), no soft belt, no thread.
