The oil casing hardening and tempering production line -China manufacturer

The oil casing hardening and tempering production line designed and produced by Forever is mainly used to process oil pipes with diameters of 60.32-114.3 millimeters, lengths of 9000-9750 millimeters, and pipe wall thicknesses of 4.83-6.88 millimeters.

The process characteristics of the Oil casing heat treament furnace :

1. The hardening heating temperature of the equipment is about 900 ° C, and the tempering heating temperature is about 650 ° C

2. The power consumption for hardening and tempering each ton of steel pipe is about 500 kWh

3. The production line has an hourly capacity of up to 1200 kilograms

4. Ensure that the temperature difference between the steel pipe core surface and the front to back temperature difference is ≤ 10 degrees

5. This set of Drill pipe induction quenching and tempering machine has the characteristics of fast heating speed, less oxidation and decarburization on the surface of the workpiece, and small deformation of the workpiece

6. The compressive stress on the surface of the workpiece after hardening greatly improves its ability to resist fatigue fracture

7. Short high-temperature treatment time and fine austenite particles

8. Excellent mechanical properties after heat treatment

9. The oil drill pipe hardening and tempering line also has the ability to uniformly heat the ends, making it suitable for handling thicker and thicker oil pipes at the ends

10. Use a walking heating device to provide online supplementary heating, ensuring even heating

The production line adopts a fully automatic control system, equipped with PLC and Advantech industrial computer, which displays real-time power operation parameters, workpiece temperature, output and water temperature records. The induction coil is designed as modular, which is easy to replace and maintain quickly, ensuring the continuity and efficient operation of production.
