Introduction and principles of induction hardening machine

This method is only induction hardening machine for strengthening a surface of a workpiece depth, while maintaining a substantially central portion of the microstructure and properties before treatment, and thus obtain high strength, high wear resistance and high toughness synthesis. Because of local heating, it is possible to significantly reduce the deformation hardening, lowering energy consumption reduction. It is because of these characteristics with high-frequency hardening, which in the machining industry widely adopted.
induction hardening machine heating principle
induction hardening machine induction heating, induction heating principle engineer explained that: the workpiece into the sensor, the sensor input is generally intermediate frequency or high frequency alternating current (1000-300000Hz or higher) hollow brass. Generating an alternating magnetic field with the frequency of the induced current in the workpiece, the workpiece induced current distribution is uneven, the surface of strong, weak in the interior, the center portion close to 0 by using the skin effect enables rapid heating of the surface, the surface temperature within a few seconds up to 800-1000 º C, and the temperature rise is small core parts.
