Principle of the workpiece into a high-frequency inductor (coil) inside, when the sensor is passed through an alternating current of a predetermined frequency, i.e. around the alternating magnetic field. Electromagnetic induction of the alternating magnetic field of the induction currents generated in the closed workpiece - vortex. Induced current distribution in the cross section of the workpiece is not uniform, the workpiece surface is very high current density gradually decreases inwardly, this phenomenon is called the skin effect. Workpiece surface high density currents of electricity into heat, so that the surface temperature rises Shandong frequency machine equipment, namely to achieve surface heating. Current higher the frequency, the workpiece surface and internal current density difference is greater the heating layer thinner. Rapid cooling in the heating layer temperature exceeds the critical temperature of the steel post, you can achieve surface hardening. High-frequency heating apparatus is the use of the magnetic field induced eddy current heating principle, the use of current through the coil generates a magnetic field, a magnetic field when the magnetic flux passes through the metal material, so that the boiler itself own high-speed heating, and then heated substance, and it is able to achieve in a short time satisfactory temperature. The main advantage of this product is magnetic heating, energy saving, environmental protection, zero emissions, unattended, water separation, piping no scaling, no fire frequency machine equipment features, easy to operate, safe and reliable Qingdao high-frequency machine equipment, durable, clean environment, easy installation, beautiful appearance, for a wide frequency machine equipment, no noise, odor, open loop, the complete absence of any risk of explosion. With anti-overheating, no leakage, anti-anti-dry due to water, anti undervoltage, overvoltage prevention, antifreeze, automatic temperature at night when electricity trough thermal storage, such as multiple intelligent protection, no smoke, no heat radiation, and many other advantages. Backwater control using high-power radiator for cooling, you can make full use of the recovered heat to improve thermal efficiency and adapt to harsh environments.
