High-frequency heating coils are now often seen in some metal processing industries. This equipment mainly heats some objects according to the induced current to meet the demand. Let Kehua introduce the design of high-frequency heating coils and the principle of high-frequency coil heating. Design of high-frequency heating coil 1. Principle of high-frequency coil heating High-frequency high-frequency current flows to the heating coil (usually made of copper tube) that is wound into a ring or other shapes. 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, so that the temperature of the object itself will rise rapidly. To achieve the purpose of heating all metal materials. Second, the application of high-frequency coil heating Induction heating can be used to heat some objects in specific parts, and can be used in surface hardening, melting, brazing, soldering, and heating objects to cooperate with other objects. Iron and steel respond best to induction heating because of their ferromagnetic properties, but any metal will generate eddy currents due to induction heating, while magnetic materials will generate hysteresis. Induction heating has been used to heat liquid conductors (eg molten metal) and plasma conductors (eg induction plasma technology). Induction heating can also be used to heat graphite crucibles (where other materials are placed), widely used in the semiconductor industry to heat silicon or other semiconductor materials. Grid frequency (50/60Hz) induction heating is commonly used in many low-cost industrial applications because it does not require an additional inverter to generate alternating current at other frequencies. Third, which professional high-frequency heating coil design Guangzhou Kehua Technology Co., Ltd. aims to 'produce energy-saving and environmentally friendly induction heating equipment to save money for usersIn January, we have developed and manufactured a full range of high-frequency induction heating equipment: medium-frequency Induction melting furnace
, ultra-sonic heating machine, ultra-high-frequency heating equipment and supporting medium-frequency diathermy forging furnace, CNC quenching machine tool, chiller and related supporting equipment, It is widely used in the metal processing industry, such as metal preheating, high frequency welding (brazing), diathermy forming, quenching, annealing, thermal fusion and other processes. All products can be customized according to customer process requirements. High-frequency heating coil design We and Kehua learned about the design of high-frequency heating coils and the introduction of high-frequency coil heating principles. Now such high-frequency heating coils are basically widely used in some industries, mainly because they can improve production efficiency.
Most places have a few choices when it comes to high frequency induction heating machine induction heating system distributors, but it can sometimes be difficult to find the right supplier for your needs. The quality of induction heating system is critical to high frequency induction heating machine.
