HF induction heating power supply

All Solid-State IGBT Drive Circuit

ROCHO high frequency induction heating power supply use the latest in all solid-state IGBT frequency conversion control technology and IGBT drive circuitry for our high-frequency induction heating power supply. This cutting-edge technology improves resonance wave form, minimizes switching losses, and ensures high-frequency tracking stability, resulting in a more stable and uniform heating performance.

Flexible Frequency Design

ROCHO high-frequency induction heating power supply operates within a rated frequency range of 30kHz to 200kHz, with a common frequency range of 30kHz to 80kHz and a heating depth of approximately 1-2mm. Widely used for surface hardening, tube heating, carbide tip welding, hot assembly, gear hardening, and more, our power supply delivers exceptional heating performance. Our engineers take into account factors such as heating depth, efficiency, location, and electromagnetic stirring force, to design a customized working frequency range that delivers optimal heating results for your specific application.

Reliable Design And Strict Testing

Each high frequency power supply undergoes rigorous testing for high power operation in the ROCHO factory, including aging and elimination of unstable components. This ensures that every unit is capable of running continuously for several months.

Applications:

High-frequency induction heating power supply has become widely used in various processes, including thermal processing, heat treatment, shrink fitting, welding, and melting of metal materials. It offers the capability of heating the workpiece as a whole or locally, enabling deep penetration of the workpiece or heating only the surface layer.
One particular application where the high-frequency induction heating power supply excels is surface hardening of metal materials, including the hardening of various hardware tools such as pliers, wrenches, hammers, axes, screwdrivers, and scissors.
It is also used for hardening of auto parts, including crankshafts, sprockets, valves, rocker shafts, transmission shafts, and shifting forks.
Other applications include welding of carbide tools such as drills, turning tools, and milling cutters, annealing of stainless steel workpieces like basins, tanks, sinks, tubes, and teacups, and even smelting of precious metals such as gold, silver, and other metal powders.
