High-frequency quenching plants can manufacture different metal parts, as well as many different types of parts. High-frequency quenching has high precision and various parts manufacturing conditions. Compared with traditional quenching equipment, Kehua high-frequency quenching will reduce a lot of work output. Improved, the finished product is also very sophisticated. Put the workpiece in the inductor made of hollow copper tube, and after passing the intermediate frequency or high frequency alternating current, 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 heated up in a few seconds). 800 ~ 1000 ℃, the core is still close to room temperature) after a few seconds, spray (immersion) water cooling (or spray immersion oil cooling) immediately to complete the immersion work, so that the surface or part of the workpiece can meet the corresponding hardness requirements. The main methods of high frequency quenching factory: Induction heating surface quenching (high frequency, medium frequency, power frequency), flame heating surface quenching, electrical contact heating surface quenching, Kehua electrolyte heating surface quenching, laser heating surface quenching, electron beam heating surface quenching . Kehua rapid heating combined with immediate quench cooling. Through rapid heating, the surface of the steel to be processed reaches the quenching temperature, and it cools rapidly without waiting for the heat to reach the center, only the surface layer is quenched into martensite, and the center is still annealed (or positive) with good plasticity and toughness. Fire and tempering) organization. Frequency selection: The relationship between the depth δ (mm) of the induced current flowing into the surface of the workpiece at room temperature and the current frequency f (HZ) is that the frequency increases, the current penetration depth decreases, and the hardening layer decreases. High-frequency quenching plant The commonly used current frequencies are: 1. High-frequency heating: 100-500KHZ, commonly used 200-300KHZ, it is a tube type high-frequency heating, the depth of the hardened layer is 0.5-2.5mm, suitable for small and medium-sized parts. 2. Intermediate frequency heating: the current frequency is 500~10000HZ, commonly used 2500~8000HZ, and the Kehua power supply equipment is a mechanical intermediate frequency heating device or a thyristor intermediate frequency generator. The depth of the hardened layer is 2 to 10 mm. Suitable for larger diameter shafts, medium and large gears, etc. 3. Power frequency heating: the current frequency is 50HZ. Using mechanical power frequency heating power supply equipment, the hardened layer depth can reach 10-20mm, which is suitable for surface quenching of large-diameter workpieces. There are many kinds of workpieces manufactured by high-frequency quenching factories, and the configuration of high-frequency quenching equipment has different requirements for workpieces, so as to achieve a high matching of equipment and workpieces, so that the quality and output can be excellent.
