The large engineering machinery on Rolling face and chain quenching and tempering, which is based on importing and absorbing Japanese similar equipment, after optimization and design this kind of machine is emergence. The machine tool has three sets of intermediate frequency powers, includes two tooling stations on the both sides and six live sections, which adopts automatic operation, this machine adopts mechanical drive and pneumatic control. Hinge pin quenching and tempering machine, mainly used in axial parts' scanning and external heat treatment, Which Integrates automatic loading, preheating, quenching, tempering and auto- unloading into one machine.
