The working principle of surface ម៉ាស៊ីន quenching ប្រេកង់ខ្ពស់

The working principle of the surface high-frequency quenching machine: the workpiece is placed in an inductor wound with a hollow copper tube, and after high-frequency alternating current is applied, an induced current of the same frequency is formed on the surface of the workpiece, and the surface or part of the part is rapidly heated ( The temperature can be raised to 800~1000℃ in a few seconds, and the heart is still close to room temperature. After a few seconds, spray (immersion) water cooling (or spray immersion oil cooling) to complete the immersion work, so that the surface or part of the workpiece reaches the corresponding temperature. Hardness requirements. The commonly used current frequency of this equipment is: 100~500KHZ, commonly used 200~300KHZ, it is high-frequency heating of electronic tube type, and the hardened layer depth is 0.5~2.5mm, which is suitable for small and medium-sized parts.
