Ultra-high frequency induction heating equipment is a kind of equipment developed for surface quenching by applying electromagnetic induction principle and modern power electronic technology. Surface heat treatment process in which the workpiece is heated locally by an induced current. This heat treatment process is often used for surface quenching, but can also be used for local annealing or tempering, and sometimes for bulk quenching and tempering.
Uhf induction heating equipment adopts IGBT efficacy, soft switching resonant dual control and frequency automatic tracking system, MOSFET devices and unique frequency conversion technology, high frequency operation is stable. Uhf INDUCTION heating equipment with constant current and power control function, greatly optimize the metal heating process. Under the same conditions, it has 50% energy saving compared with the traditional high cycle electron tube heating equipment, no high cycle radiation, no high cycle drying. Reduced power load and power capacity, with 100% full load design, UHF induction heating equipment can work continuously for 24 hours without interruption. With automatic heating, insulation, cooling three periods of function Settings, is conducive to improve the heating quality of UHF induction heating equipment, simplified manual operation. Uhf induction heating equipment can be selected according to the power and frequency. The higher the high frequency, the shallower the heating depth, and the lower the high frequency, the better the diathermy. Induction heater 1 ~ 20KHZ high frequency automatic tracking.
UHF heating equipment has the advantages of high frequency, small size, light weight, energy saving, solid and beautiful solder joints, almost unlimited welding part shape, surface pattern will not be damaged, the metal internal crystal structure unchanged, small annealing range and so on. , no obvious welding scar, widely used in metal glass manufacturing, electrical and electronic industry connector welding, small relay internal non-contact welding, refrigeration industry high pressure welding, jewelry industry parts welding, manufacturing metal jewelry and process welding.
