Long bar quenching and tempering

Long bar quenching and tempering systems are used for heat treatment of long bar, pipe, drill pipe, rod,wire, plate etc.

Induction quenching processes are used to impart specific mechanical properties to a component in order to render it fit for use. Induction tempering is used to eliminate residual stress generated in quenching process, prevent deformation and cracking. At the same time, it will adjust the workpiece hardness, strength, plasticity and toughness
