Piston rod quenching and tempering intermediate frequency heating furnace

Piston rod quenching and tempering intermediate frequency heating furnace

The piston rod quenching and tempering intermediate frequency heating furnace is mainly composed of a mechanical conveying device, an intermediate frequency quenching heating module, an intermediate frequency tempering heating module, a closed cooling system, an infrared temperature measuring device, a quenching cooling device, and an intelligent console. The mechanical conveying device consists of a storage table, a turning frame, a nip roller feeding device, and a discharge frame.

The quenching heating, spray cooling, and tempering heating of the piston rod quenching and tempering intermediate frequency heating furnace are all continuous operations; the temperature uniformity is controlled at ±5℃, the hardness after tempering is controlled within 30HRC, the deformation is small, and the resistance after modulation Tensile strength, yield strength, and elongation are 10~15% higher than resistance furnaces.
