High frequency heating machine principle High heating efficiency

I believe that many friends in life are not very clear about the principle of high-frequency heating machines. After all, we do not often come into contact with such knowledge, and it is very normal to not know. Next, let’s follow Xiaobian and Kehua together to understand High frequency heating machine principle High frequency heating machine principle High frequency heating machine is currently the most efficient, fastest, low-consumption, energy-saving and environmentally friendly induction heating equipment for metal materials. High-frequency heating machine, also known as high-frequency machine, high-frequency heating machine Frequency induction heating equipment, high frequency induction heating device, high frequency heating power supply, high frequency power supply, high frequency electric furnace. High-frequency welding machine, high-frequency induction heating machine, high-frequency induction heater (welder), etc., as well as intermediate frequency induction heating equipment, ultra-high frequency induction heating equipment, etc. The application range is very wide, such as metal heat treatment brazing melting. 1. Heat treatment: local or overall quenching, annealing, tempering, and heat penetration of various metals; 2. Hot forming: whole piece forging, partial forging, hot heading, hot rolling; 3. Welding: brazing of various metal products Welding, welding of various tool blades, saw blade teeth, steel pipe, copper pipe welding, welding of dissimilar metals; 4. Metal smelting: (vacuum) smelting, casting and forming of gold, silver, copper, iron, aluminum and other metals Evaporation coating; 5. Other applications of high frequency heating machine: semiconductor single crystal growth, heat fitting, bottle mouth heat sealing, toothpaste skin heat sealing, powder coating, metal implantation in plastic. Principle of high-frequency heating machine Features 1. Solid-state (transistor) high-frequency uses IGBT as the main device, full-bridge inverter; 100% load duration design, can work continuously. 2. Perfect protection function and high reliability; small size, light weight, simple installation and convenient operation. 3. Adopt frequency automatic tracking and multi-channel closed-loop control. 4. Substitute oxyacetylene flame, coke furnace, salt bath furnace, gas furnace, oil furnace and other heating methods. 5. It can be remotely controlled and connected with infrared temperature measurement to realize automatic temperature control, improve heating quality and simplify worker operations. Working principle High-frequency high-frequency current flows to the heating coil (usually made of copper tube) that is wound into a ring or other shape. As a result, a strong magnetic beam with an instantaneous change in polarity is generated in the coil. When a heated object such as a metal is placed in the coil, the magnetic beam will penetrate the entire heated object, and in the opposite direction of the heating current inside the heated object, it will generate Correspondingly large eddy currents. Due to the existence of resistance in the heated object, a lot of Joule heat will be generated, and the temperature of the object itself will rise rapidly. To achieve the purpose of heating all metal materials. Many friends may not understand the principle of high-frequency heating machine. After all, not everyone is interested in electronic knowledge, but it is also useful for us to know more. If you want to know more, then Follow Kehua.
