What are the characteristics and precautions of self-made induction heating

As the saying goes, do it yourself, I believe many friends like to try some homemade suggestions for small equipment hobbies at home. But I don't know if you have tried a small device like homemade induction heating? Kehua shares some tips on homemade induction heating for everyone. Self-made induction heating The utility model relates to an electromagnetic induction heater, which is mainly suitable for non-industrial heating objects and cooking food such as households and restaurants. Existing electromagnetic induction heaters usually use the turn-on and turn-off of high-power triodes to periodically supply power to the induction heating coil and capacitor to form an alternating magnetic field to heat objects. For example, the electromagnetic induction heaters disclosed in Japanese Patent Application Publication No. Sho 63-25473 and Japanese Patent Application Publication No. Sho 61-45591 are of a direct heating method and have higher thermal efficiency than an indirect heating method. However, because the diodes connected in reverse parallel at both ends of the high-power triode will be turned on and consume power when the triode is subjected to reverse voltage, the base of the triode needs to consume a certain amount of power during the entire time that the triode needs to be turned on, and the conduction of the triode The turn-on and turn-off are easily affected by external circuits, which will increase the power consumption of the circuit. The task of the present utility model is to provide an electromagnetic induction heater, which can further reduce the power consumption of the induction heater, improve the thermal efficiency and make the structure simpler. Self-made induction heating induction heating equipment is a kind of three-phase power frequency alternating current, rectified into direct current, and then the direct current into an adjustable current, supplying the alternating current flowing through the capacitor and the induction coil, in the induction coil Generate high-density magnetic lines of force, and cut the metal material contained in the induction coil, generating a large eddy current in the metal material. In the technology of Shanghai Ougan Electric Technology, a metal cylinder is placed in the induction coil with alternating intermediate frequency current. The metal cylinder is not in direct contact with the induction coil. The temperature of the energized coil itself is very low, but the surface of the cylinder is heated to Redness and even melting, and the speed of this redness and melting can be achieved by adjusting the frequency and the strength of the current. If the cylinder is placed in the center of the coil, the temperature around the cylinder will be the same, and the heating and melting of the cylinder will not produce harmful gases or pollute the environment with strong light. In fact, the process of self-made induction heating requires a lot of special attention. Interested friends can try to do it, but if you want to have a real demand for induction heating equipment, it is recommended to choose Kehua regular equipment.
