The higher the frequency of the current passed in the output coil, the less the penetration depth of the induced current generated on the surface of the heated body. The skin effect is more obvious. According to the calculation of the penetration depth of the induced current and the actual application, we give the following reference frequency selection: <br> <br>Surface Heating (such as hardening) <br>Hardening depth 0.8-1.2mm, the heating machine frequency should be at the range of 200-400KHZ <br>Hardening depth 1-2mm, the heating machine frequency should be at the range of 60-200KHZ <br>Hardening depth 2-4mm, the heating machine frequency should be at the range of 15-30KHZ <br>As one of the professional induction hardening machine manufacturers in China, JKZ strongly recommends you to select the frequency range in accordance with the needs of your workpieces.  <br> <br>Whole Piece Heating (such as induction forging application) <br>Workpiece diameter 20-30mm, the induction heater frequency should at the range of 15-30KHZ <br>Workpiece diameter 30-50mm, the induction heater frequency should at the range of 6-15KHZ <br>Workpiece diameter 50-80mm, the induction heater frequency should at the range of 2-5KHZ <br>Workpiece diameter above 80mm, the induction heater frequency should within 2KHZ <br> <br>Induction Melting <br>According to the metal material and melting capacity, the induction melting machine frequency should choose 3-30KHZ <br> <br>Induction Brazing <br>According to the brazing material, welding depth, workpiece thickness, the induction brazing frequency range should be 15-300KHZ <br> <br>If you are looking for a reliable induction heating company, don&#039;t hesitate to contact us!

In order to improve the hardness of metal&#039;s surface, not only should the surface layer depth of the workpiece reach the industrial design standard, but the heat treatment production plants are also needed to introduce the hardening process in the production. Functioning as an effective tool to implement the induction hardening process of steel, the induction hardening machine occupies an irreplaceable position in many heating methods, especially in the control of layer depth and temperature control. As a mature induction hardening machine manufacturers, JKZ sells 1-10KHZ medium frequency induction furnaces, 15-30KHZ ultrasonic frequency induction heaters, 30-60KHZ high-frequency induction heating machines, and 50-120KHZ super high-frequency small induction heating machines of high quality. These induction hardening machine hold the power range from 7.5KW to 600KW, which can process workpieces with a diameter up to 2000mm and hardening depth from 1 to 20mm. Moreover, capable of working together with CNC/PLC hardening machine scanner system, JKZ&#039;s Induction heating equipment can also accurately control the induction heating coil moving speed, workpiece rotation speed, power output percentage, layer depth, and quenching liquid spray time. Thus, if you are still looking for a tool to conduct effective application of induction surface hardening, our industrial heating unit can then perfectly meet all your needs for the hardening and heating processes. <br> <br>Induction Hardening VS Case Hardening <br>Comparing the two methods of quenching steel workpieces, the first significant difference is part handling. Surface hardening can process a large number of workpieces at the same time, while induction hardening focuses on a single workpiece. Through induction hardening, the parts are quenched one by one. <br>Case hardening relies on parts logistics to transport parts between the production line and hardening. Induction hardening can be directly integrated into the production line as part of the cycle with a suitable hardening machine. <br>Case hardening in detail <br>As mentioned above, surface hardening is carried out in batches. As with induction hardening, the goal is to harden the outer layer of the workpiece. <br>In the case of quenching, the workpiece is hardened by carburizing. The steel is heated above 880°C to become austenite. The coal is then transferred from the CO emission medium to the part through the surface of the part. Diffusion causes the edges of the workpiece to receive more carbon, while the carbon density in the center remains the same. <br>There are two ways to influence the depth of hardening in surface hardening: one is to manipulate the heating of the workpiece, for example, by using a special paste to prevent certain places from being heated. The other is by influencing the quenching process, for example by immersing only certain parts of the workpiece. <br>Using these two methods, the results are not particularly accurate, and can only be reproduced within a relatively wide tolerance range. This is very different from induction hardening. <br>Induction hardening in detail <br>As mentioned above, each part is individually quenched using induction hardening technology. Each part is heat treated, quenched and annealed separately. In addition to being integrated into the production line, the great advantage of induction hardening is the precise control and reproducibility of the quenching results. In order to achieve this, the entire hardening process from the inductor and the applied energy and frequency to quenching and annealing has been specifically adjusted for the relevant workpiece. Even for workpieces with complex geometries, this can produce excellent quenching results.

Taking &quot;win-win with customers&quot; as our value foundation, JKZ Induction Heating, with our complete R&amp;D designs, project solutions, production team, and after-sales support, are looking forward to cooperating with you. <br> <br>Compare different types of induction heating equipment <br> <br>Different Frequencies <br>Induction tempering machine with a frequency of 1-10Khz is usually regarded as medium-frequency induction heating equipment, and induction heating equipment with a frequency above 50Khz as high-frequency induction heating equipment. <br> <br>Different Quenching Depth <br>Affected by the frequency of heat induction machine, the quenching depth of the two is also different. The quenching depth of medium frequency induction heating equipment is generally 3.5-6mm, while that of high frequency induction heating equipment is 1.2-1.5mm. <br> <br>Different Diathermy Diameters <br>Medium frequency induction heating equipment has great advantages in the diathermy of workpieces. It is mainly used for diathermic heat treatment of workpieces. It can perform diathermic heat treatment on workpieces with a diameter of 45-90mm. However, high-frequency induction heating equipment can only dilute the thin and small workpieces. <br> <br>Induction Heating VS Other Heating Methods <br>Induction heating is different from some common heating methods in that it does not rely on convection and radiation to transfer heat to the surface of the product. Instead, the surface of the product generates heat through current, and then the heat from the surface of the product is transferred to the product through heat conduction. The depth of direct heating using induction current depends on the electrical reference depth. <br> <br>Unlike some combustion methods, induction heating can be precisely controlled regardless of batch size. By changing the current, voltage and frequency of the induction coil, fine-tuned engineering heating can be achieved, which is very suitable for precision applications such as surface quenching, quenching and tempering, and annealing. The precise heating control provided by induction is unparalleled. In addition, using the same heating principle as the vacuum crucible heating application, induction heating can be carried out in the atmosphere for continuous application. For example, bright annealing of stainless steel tubes. <br> <br>Features of Induction Heating Machines <br>High precision heating is essential for key applications such as automotive, aerospace, fiber optics, ammunition bonding, wire hardening, and spring wire tempering.
