Function and advantages of high frequency quenching machine

The high-frequency quenching machine winds the hollow copper tube sensor workpiece, and is fed with intermediate frequency or high-frequency alternating current to form the frequency of the induced current on the surface of the workpiece. 1000℃, the heart is still closed at room temperature) after a few seconds of rapid injection (immediate cooling water (DIP) or spray cooling oil) to complete the extraction of fire, the high frequency quenching machine makes the surface or part of the workpiece meet the corresponding hardness requirements . The high-frequency quenching machine strengthens the surface of the workpiece to a certain depth, while the core basically maintains the structure and properties before treatment, so a combination of high strength, high wear resistance and high toughness can be obtained. And because it is local heating, it can significantly reduce quenching deformation and reduce energy consumption. The high-frequency quenching machine makes the surface of the steel to be processed reach the quenching temperature through rapid heating, and cools rapidly without waiting for the heat to reach the center. Annealed (or normalized and tempered) organization with good toughness.
