Piston Rod Quenching and Tempering Line
The piston rod tempering line is the core heat treatment production facility that ensures the mechanical performance of piston rods, catering to manufacturing needs in hydraulic and pneumatic applications. It imparts balanced strength and toughness to the final product. Targeting forged and rolled piston rod billets, the process begins with medium-frequency induction heating to reach quenching temperature, followed by rapid cooling—either through water or oil quenching—to harden the material. Finally, the parts undergo controlled-temperature tempering to relieve internal stresses and stabilize the microstructure.
