Ultra high frequency induction heating system is an advanced heating technology that uses very high frequencies (generally referring to the frequency range above 100kHz) for induction heating. This heating method mainly relies on the principle of electromagnetic induction, which can generate high temperatures in an instant and is suitable for precision heating of metal materials, such as welding, surface hardening, hot assembly, and other processes. Compared to low-frequency and mid frequency induction heating, ultra-high frequency induction heating systems have higher heating rates and more precise heating control capabilities.

working principle

Ultra high frequency induction heating mainly utilizes the high-speed changing magnetic field generated by high-frequency alternating current in the induction coil, which excites strong eddy currents in the target metal. Due to their extremely high frequency, these vortices concentrate in thin layers on the metal surface, causing rapid surface heating while the interior is relatively cold. This phenomenon is called the "skin effect", making ultra-high frequency induction heating very suitable for surface treatment of metal materials.

Characteristics and advantages

Rapid heating: Ultra high frequency means extremely fast heating speed, which can reach the desired temperature in milliseconds.

Precise control: capable of achieving highly precise temperature and depth control, suitable for workpieces with complex shapes and sizes.

Local heating: only heats the surface or specific area of the workpiece, without affecting the overall properties, reducing material waste and thermal stress.

Efficient and energy-saving: Compared to other heating methods, it has high energy conversion efficiency and is energy-saving and environmentally friendly.

Environmental safety: No need for fuel combustion, no smoke or gas emissions, and a cleaner operating environment.

application area

The ultra-high frequency induction heating system is widely used in the following fields due to its unique heating characteristics and advantages:

Metal welding: precision welding of small parts and electronic components.

Surface hardening: By locally quenching, the surface hardness of the workpiece is increased without changing the core properties.

Hot assembly: used for heating assembly of tight fitting parts.

Precision casting: precise control of metal melting and casting processes.

Research experiment: Conduct rapid heating tests in materials science and physics experiments.

Development Status and Trends

With the advancement of technology, ultra-high frequency induction heating systems continue to innovate in technology, developing towards higher frequencies, greater power, and greater intelligence. In addition, the increasing demand for environmental protection and energy efficiency has prompted researchers in this field to explore more green and low-carbon solutions, such as using more efficient cooling systems and intelligent control systems to further enhance the overall performance of equipment.

In the future, ultra-high frequency induction heating systems are expected to play a role in a wider range of industrial fields and become one of the key technologies driving the upgrading and transformation of the manufacturing industry.
