Piston rod heat treatment line process and work process description:

1,  Heat treatment process: steel pipe is placed on the loading platform by the crane to carry out the baling → feeding machine feeding → variable frequency feeding roller road to transport the steel pipe forward → quenching medium frequency induction heating sensor (low temperature) furnace, (high temperature) furnace heating to 950 °C infrared temperature measurement and feedback composition closed-loop control adjustment medium frequency induction heating furnace power → spray quenching → lift the pipe through the turning machine and put it on the residual water draining device in the pipe → lift the pipe back through the turning machine On the hot roller road → (low temperature) tempering induction heating furnace → (high temperature) tempering medium frequency induction heating sensor (heating) heating to 450 ~ 760 ° C infrared temperature measurement and feedback composition closed loop control adjustment medium frequency induction heating furnace power → turning machine → Chain bi-directional cooling bed → turning machine → discharging .

The piston rod heat treatment line production line adopts intelligent series resonant intermediate frequency power supply control features:

● Parallel resonance design, phase shifting and power adjustment, the equipment is mature and stable; it has more advantages in the high power range above 3000KW.

● DSP control, the speed capture phase lock starts, meets frequent start and stop, and the success rate is 100%.

● Variable frequency variable load adaptation, frequency adaptation range 200-10000Hz, induction furnace replacement automatic matching, no manual adjustment is required.

●T2 copper copper row in the cabinet, sandblasted and passivated; low leakage and anti-oxidation, effectively reducing line loss.

● Full touch screen control, pure digital setting, complete process record and strict hierarchical authority. The main parameters can be restored to the factory settings with one key.

● The device has self-protection function (overcurrent, overvoltage, water pressure, phase loss, undervoltage, overload). If it encounters the situation, the device has self-diagnosis function.

Piston rod heat treatment line production line configuration composition and characteristics:

1. Quenching medium frequency power supply range: KGPS160-1300KW

2. Tempering medium frequency power supply range: KGPS160-750KW

3, quenching, tempering sensor (including capacitor group, water, gas, etc.)

4. Closed cooling system for intermediate frequency power supply and sensor

5, copper row connection wire (connection between power cabinet and induction furnace)

6, input and output system (the workpiece rotates on one side, the average speed feeds on one side, and the operation is stable, the speed is adjustable, the heating is more uniform)

7, quenching, tempering spray system

8. Quenching and tempering infrared temperature measuring device (with American Leitai infrared thermometer to display the temperature of the workpiece in real time, so that the workpiece can be viewed at any time during the quenching and tempering process)

9, Plc control system, (can control the operation of the entire mechanical part, man-machine interface, all digital, highly humanized operation)

10, the central console (including frequency control and temperature control, Huayan industrial computer, remote start, etc.) its role is to operate the entire quenching and tempering equipment directly on the center console, only one person can operate the entire set of equipment , saving labor and saving costs.
