How to make simple high frequency induction heating simple high frequency induction heating principle-Kehua

High-frequency induction actually uses induction current limiting to cause self-heating. High-frequency induction heating coils can actually be self-made, so how to make simple high-frequency induction heating? What is the principle of simple high-frequency induction heating? Let's go to Guangzhou together Take a look at Kehua Co., Ltd. Homemade simple high frequency induction heating How to make simple high frequency induction heating to make a pure copper tube into a coil, use an iron mold or a wooden mold when winding, considering the amount of springback after the copper tube is wound, so the mold should be The size is slightly smaller than the required size. When the winding radius is small, hot winding should be performed, that is, acetylene flame is used to bake the pure copper tube at the bending part during winding, and the wound coil will be corrected to the required size. , and press it with a clamp. Homemade Simple High Frequency Induction Heating Simple High Frequency Induction Heating Principle Induction heating surface quenching uses the principle of electromagnetic induction to generate a high-density induced current on the surface layer of the workpiece, which is rapidly heated to austenite state, and then rapidly cooled to obtain a martensitic structure According to the quenching method, when an alternating current of a certain frequency passes through the induction coil, an alternating magnetic field with the same frequency as the current changes will be generated inside and outside it. When the metal workpiece is placed in the induction coil, under the action of the magnetic field, an induced current with the same frequency as the induction coil and the opposite direction will be generated in the workpiece. Because the induced current forms a closed loop along the surface of the workpiece, it is often called an eddy current. This eddy current converts electrical energy into heat, rapidly heating the surface of the workpiece. Eddy currents are mainly distributed on the surface of the workpiece, and there is almost no current passing through the workpiece. This phenomenon is called surface effect or skin effect. Induction heating uses the skin effect to rapidly heat the surface of the workpiece to the quenching temperature by means of the current thermal effect. The induction coil is made of copper pipe, and cooling water is passed through it. When the surface of the workpiece is heated to a certain temperature in the induction coil, it is immediately cooled by water spray, so that the surface layer can obtain a martensite structure. The above is the relevant introduction about self-made simple high-frequency induction heating. When making simple high-frequency induction heating coils, you must pay attention to safety.
