Long Shaft Hardening and Tempering Production Line

This series induction heating machine is suitable for all kinds of long metal bar induction hardening and tempering treatment. It replaces the traditional pit heating furnace, car-bottom type furnace. It adopts CNC control system to realize the automatic loading, heating, spray cooling, high-temperature tempering, and automatic unloading of the work-pieces.


1. It has the function of automatic loading and unloading.

2. With multi-stage heating protection, it ensures the temperature uniformity, at the same time, before cooling the work-piece and after tempering; the furnace with the thermo detector can measure the temperature of the bar.

3. The power and the temperature for the hardening and tempering, and the work-piece feeding speed are all controlled automatically by the system. It has the function of temperature closed loop for optional.

4. Heating power, voltage, current, frequency, tempering power, tempering power voltage, heating feeding speed, hardening temperature, tempering temperature, etc are all designed and recorded by the system, and the technical parameters can be tracked.

5. High strength welded bed, aging treatment and stability.

6. Work-piece rotation moving motor: frequency and speed control system.

7. Inductor change: manual water-electricity quick coupler.

8. The coil adopts changeable pitch of turn, high efficient and energy saving.

9. The power supply and the heating furnace have the function of water pressure protection, water flow protection, water temperature protection, air pressure protection and photovoltaic safety protection.

10. Control cabinet: control cabinet all in one control box.

11. Alarm: Acoustic/optical fault alarm, the alarm information is displayed in the control interface and can be recorded.

12. Inductor and water sprayer cooling connector: stainless steel/brass quick coupler.

13. Electrical control method: PLC / touch screen +PLC.

14. The control system can monitor and record all technical parameters, and it has the function of inquiring historic data, monitoring on line, outputting and printing, etc.

15. With the automatic loading and unloading systems, it realizes the equipment automatic quenching and tempering.
