Application

: Induction Quenching/Hardening; Quenching is to heat the material above the phase transition temperature, and to keep the microstructure of the material sufficiently transformed into austenite during a certain period of time. Then, the material is cooled rapidly and the martensite microstructure is obtained. Quenching is mainly to obtain higher hardness and better wear resistance. It is mainly used for carburizing parts such as gear, shaft, motor, roller, knife edge, screw, mould, track and so on.

: Induction Welding; Welding is mainly used for manufacturing precision instruments, electrical components, heterogeneous metal components and complex thin plate structure,Such as sandwich structure, honeycomb structure, etc., also used to braze various kinds of wires and cemented carbide knifes. The liquid filler metal can expand and dissolve along the joint by capillary action to form alloy layer. It is widely used in machinery, motor, instrument, radio and other industry.

: Induction Smelting; Melting is to put the metal material and other auxiliary materials into the furnace and to heat to liquid. Melting is often used in adjusting the content of alloying elements, carbon adjustment, deoxidization, degassing, taking off non-metallic inclusion process of metal purification, as well as scrap metal recycling.

: Induction Annealing/Normalizing; Annealing is to reduce hardness and improve machinability; Eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine the grain, adjust the structure, eliminate the structure defect. The annealing purpose of the new material is similar to that of the traditional metal annealing. In the production, annealing process is widely used. According to the requirements of the workpiece annealing, there are many kinds of annealing process specifications, commonly used are complete annealing, spherical annealing, and stress relief annealing.

: Induction Forging; Forging is divided into two parts, forging and stamping. It is a kind of processing method which uses the rolling machine to press the metal blank and make it produce plastic deformation to obtain the forging workpiece with certain mechanical properties, certain shape and size. It is used in wheel parts, steel ball, transmission shaft and metal parts treatment such as upsetting, drawing out, punching, cutting, bending, twisting, offsetting, die forging and so on.

: Shrink Fitting; Shrink fit is the connection which is realized by the tolerance of two connecting pieces themselves, which can be divided into pressing fit, hot fitting and cold fitting. Common used in assembly of rotor, spindle, bearing, bottle cap, motor, mold and other central shaft.
