Oil drill pipe induction quenching & tempering machine

Product use: Suitable for quenching and tempering heat treatment of metal workpieces such as steel bars, steel pipes, stainless steel pipes, oil drill pipe ,oil casting etc

quenching: 500KW/1000HZ

Quenching pier head reheating:120KW/1000HZ

Whole tempering: 200KW/500HZ

Tempering pier head reheating:80KW/500HZ

Production capacity: 1.5-10 tons/hour

Scope of application: 60.3 * 4.83 * 9.9; 73.02*5.51*9.9; 88.9*6.45*9.9; 114-139.7; 188.28-219.08;

1. Power supply system: quenching power supply+tempering power supply

2. The hourly output is 0.5-3.5 tons, with a suitable range of 020-0120mm and above.

3. Conveyor roller conveyor: The axis of the roller conveyor forms an angle of 18-21 with the axis of the workpiece. The workpiece rotates while moving forward at a constant speed, making heating more uniform. The roller conveyor between the furnace bodies is made of 304 non-magnetic stainless steel and water-cooled.

4. Roller grouping: The feeding group, sensor group, and discharge group are independently controlled, which is beneficial for continuous heating without creating gaps between workpieces.

5. Temperature closed-loop control: Both quenching and tempering use the American Raytheon infrared thermometer closed-loop control system for precise temperature control.

6. Industrial control computer system: Real time display of the current working parameter status, workpiece parameter memory, storage, printing, fault display, alarm and other functions.

7. Energy conversion: using quenching+tempering method, with a power consumption of 280-320 kWh per ton.

8. The human-machine interface PLC fully automatic intelligent control system ensures worry free production with "one click start".

The working process of the mechanical system of the tempering furnace equipment:

Crane crane, material storage platform, automatic feeding mechanism, feeding roller system, quenching induction heating system, infrared temperature measuring device, discharge roller system, spray quenching system, quenching completion, tempering conveying system, tempering induction heating system, infrared temperature measuring device, discharge roller system, cooling mechanism, and receiving rack.

1. Adopting a new IGBT air-cooled induction heating power supply control, it has low power consumption, energy saving and environmental protection, and high production efficiency.

2. The quenching and tempering furnace equipment designed by Yuantuo adopts V-shaped rollers arranged diagonally in the transmission design to reduce radial runout.

3. Fast heating speed, minimal surface oxidation, quenching and tempering process achieved during rotary heating, resulting in good straightness and no bending of the steel after quenching and tempering.

4. After heat treatment, the workpiece has extremely high consistency in hardness, uniform microstructure, high toughness, and impact strength.

5. The PLC touch screen control system can record and save all process parameters of induction hardening and tempering of workpieces, making it convenient for you to view historical records in the future.
