Description
The sucker rod tempering equipment from Hebei Yuantuo Electromechanical is designed for high-capacity, large-diameter oilfield rods, integrating induction heating, end-face and surface tempering, quenching, and straightening in a single production line.
Also referred to as sucker rod tempering production line, sucker rod heat treatment equipment, or sucker rod induction Q&T system, this solution ensures uniform hardness along the rod, optimized toughness, and stable metallurgical properties, even for rods with complex geometry or thick sections.

🔹 Heat Treatment Requirements for Oilfield Sucker Rods
Sucker rods operate under:
* Cyclic tensile and compressive loads
* Extreme fatigue and wear conditions
* Surface and end stress concentration
The sucker rod tempering line ensures:
* Uniform hardness from rod head to rod body
* Surface and end-face tempering for wear resistance
* Consistent mechanical properties across batches
* High throughput suitable for industrial-scale production

🔹Key Process Capabilities
* Medium-frequency induction heating of rod surface and core
* End-face hardening for rod heads
* Integrated quenching and tempering for optimized strength and toughness
* Continuous automated operation
* PLC/HMI-controlled power and speed adjustment
* Fully compatible with rods up to Φ42 mm (hollow) and Φ85 mm (solid)
>Key Selling Point: The heat treatment temperature and hardness of the clubhead and shaft are consistent, and heating is uniform—thereby eliminating the need for an additional straightening machine.
🔹 Sucker Rod Tempering Production Line Configuration
1. Automatic loading and feeding system
2. Medium-frequency induction heating coils
3. Rotational + forward-feed conveyor system for uniform heating
4. Spray or water sleeve quenching system
