Applications

Induction heating is an efficient heating technology that utilizes the principle of electromagnetic induction. It generates a magnetic field through alternating current in a coil, which induces eddy currents inside conductors such as metals—these eddy currents are then converted into thermal energy (magnetic materials also generate supplementary heat through hysteresis). This technology boasts key advantages including high thermal efficiency (60%-95%), non-contact operation without contamination, precise control over temperature and heating depth, and rapid response with no preheating required. In the industrial sector, it is applied in metallurgical melting, brazing and heat treatment of aerospace components, as well as pre-weld preheating and post-weld treatment of oil and gas pipelines. In civilian scenarios, it is widely used in the form of induction cooktops, induction heating boilers, and precision heating equipment for food processing, featuring both clean and energy-efficient properties.
