Process flow and working process description of round pipe and steel pipe quenching and tempering production line :

1.  Heat treatment process: the steel pipes are placed on the loading platform by the crane for bulk bundling → feeding machine feeding → frequency conversion feeding roller table to transport the steel pipe forward → induction heating furnace heated to 950 ℃ for quenching , infrared temperature measurement and feedback Composed of closed-loop control to adjust the power of the induction heating furnace → spray quenching → lift the tube by the turning machine and put it on the water draining device → lift the tube by the turning machine and put it on the tempering roller table → enter the induction heating furnace → ( Tempering ) heating to 450～760℃ infrared temperature measurement and feedback to form a closed-loop control to adjust the power of the induction heating furnace → turning machine → chain two-way cooling bed → turning machine → discharging . 

   

   2. Summary of parameters of steel pipe quenching and tempering production line

The steel pipe quenching and tempering production line adopts intelligent intermediate frequency power supply control features:

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

●DSP control, fast capture phase lock start, meeting frequent start and stop, 100% success rate.

●Frequency conversion and load adaptation, frequency adaptation range 200-10000Hz, automatic matching for induction furnace replacement, no manual adjustment is required.

●T2 red copper copper bars are used in the cabinet, which are sandblasted and passivated; low leakage inductance, anti-oxidation, and effectively reduce line loss.

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

●The equipment has self-protection function (over current, over pressure, water pressure, lack of phase, under voltage, overload), and the equipment has self-diagnosis function in case of situation.

Configuration composition and characteristics of steel pipe quenching and tempering production line :

1. The range of quenching medium frequency power supply: KGPS160-1300KW

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

3. Quenching and tempering sensor (including capacitor bank, water circuit, gas circuit, etc.)

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

5. Copper bar connecting wire (connection between power cabinet and induction furnace)

6. Input and output system (while rotating, while feeding at a constant speed, and the operation is stable, the speed is adjustable, and the heating is more uniform)

7. Quenching and tempering spray system

8. Quenching and tempering infrared temperature measuring device (equipped with the real-time temperature displayed by the American Raytech infrared thermometer, so that the temperature uniformity can be seen 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, full digital, highly humanized operation)

10. The central console (including variable frequency speed regulation and temperature control, Huayan industrial computer, remote start, etc.) is to operate the entire quenching and tempering equipment directly on the central console, and only one person can operate the entire equipment , Save labor and save costs.

Performance characteristics of steel pipe quenching and tempering production line :

1. The quenching and tempering production line has a simple structure and reliable performance, which can meet different heat treatment processing requirements, and the equipment is simple to operate and easy to maintain;

2. The processed products have beautiful appearance and strong production capacity. Using the principle of electromagnetic induction heating , the quality of processed products is excellent, the heating is uniform, and the temperature difference between the core and the surface is small;
