Description
The screw rod tempering equipment from Hebei Yuantuo Electromechanical is designed for precision rods, piston rods, and automotive torsion rods, integrating medium-frequency induction heating, quenching, tempering, and straightening in a fully automated line.
Also referred to as screw rod tempering machine, piston rod tempering equipment, or precision rod heat treatment furnace, it delivers uniform hardness, optimal toughness, and repeatable mechanical properties for industrial-scale production.
🔹 Key Process Capabilities
* Continuous induction heating and tempering for screw rods, piston rods, and torsion rods
* End-face and surface tempering for high-wear areas
* Uniform hardness along the rod length and diameter
* Automated quenching and tempering controlled by PLC/HMI
* Continuous rotation and forward feed for even heat treatment
* Adjustable for rod diameters and lengths (Φ16–85 mm, up to 6 m)
🔹 Production Line Overview
The precision rod tempering line is engineered as a single integrated system, combining:
* Rod loading and feeding mechanism
* Medium-frequency induction heating module
* Quenching section for surface and end-face hardening
* Tempering section for mechanical property optimization
* Straightening module for dimensional accuracy
* Cooling and discharge system
> This layout enables full-process automation from loading to discharge, eliminating the need for additional separate furnaces or straightening machines, suitable for Lead Screw Quenching and Tempering Production Line and Piston Rod Medium-Frequency Quenching Machine applications.
