The difference between intermediate frequency quenching equipment and traditional quenching equipment

Intermediate frequency quenching equipment is currently a commonly used metal heat treatment equipment for metal quenching and heat treatment. In order to make mechanical workpieces with high strength, high wear resistance and high toughness, the heat treatment plant favors intermediate frequency quenching equipment in various machinery industries. Intermediate frequency quenching equipment is a heat treatment method that uses intermediate frequency current to quickly heat and cool the surface of the workpiece, so as to harden the surface of the workpiece.

The alternating magnetic field produces an induced current of the same frequency in the workpiece. The distribution of this induced current on the workpiece is uneven. It is strong on the surface but weak on the inside. It is close to 0 to the core. Use this skin effect , Can make the surface of the workpiece heat up quickly. The intermediate frequency heating equipment only strengthens the surface of the workpiece to a certain depth, while the interior basically maintains the original structure and performance. At the same time, the local heating method can significantly reduce the quenching deformation and reduce the damage rate of the workpiece.

The traditional quenching machine heats the metal workpiece to an appropriate temperature and keeps it for a period of time, and then immerses it in a quenching medium for rapid cooling of the metal heat treatment process. Commonly used quenching media are brine, water, mineral oil, air and so on. Unable to achieve under some technical conditions, process defects, etc.

The outstanding performance advantages of intermediate frequency quenching equipment: stable performance, comprehensive protection measures, safety and reliability; fast heating speed, induction heating without oxide layer, small deformation of the workpiece; small size and split structure, light weight and convenient installation; energy saving and environmental protection, no pollution; It is suitable for processing a variety of workpieces with strong energy; adopts the core technology imported from Germany to save electricity and cost; the heating time of the workpiece is accurately controllable, the processing quality is high, and the product performance is good.
