High-frequency heating electromagnetic coil high-frequency heating, that is, induction heating is a method of using electromagnetic induction to heat an electric conductor (usually a metal material), which will cause an eddy current in the metal material, and the metal material is caused by electromagnetic induction. Warm up instantly. Induction heaters, also commonly called electromagnetic coils, are based on high-frequency alternating currents, which follow the size of the heating body's own magnetic permeability to determine the efficiency of heating. The frequency of the exchange used is determined by the type of metal of the article to be heated, the degree of bonding of the heating coil and the article to be heated, and the depth of penetration.
Induction heating can be used to warm certain parts of a particular part, and can be used in the surface hardening, melting, brazing, soft-fibre welding, and heating items to interact with other items. Due to the characteristics of its ferromagnetic materials, iron and steel have the best reflection of induction heating. Only all metal materials are caused by eddy currents due to induction heating, while permanent magnet materials cause hysteresis problems. Induction heating has been used to heat liquid conductors (such as molten metal) and plasma conductors (such as inductive plasma technology). Induction heating can also be used to heat graphite crucibles, where other materials are placed, to heat silicon or other semiconductor materials widely in the semiconductor industry. Power grid frequency (50/60Hz) induction heating is caused by the use of additional inverter power to cause AC current at other frequencies, which is common in many low-cost industrial production applications.
Induction furnace
The medium frequency induction furnace uses a magnetic induction method to melt the metal material. After melting, the high-frequency magnetic field can also agitate the metal. If the alloy is made, it can ensure that the added metal and the original metal are fully mixed. Most induction furnaces include a water-cooled copper ring with a layer of heat-resistant material on the outside. Induction furnaces are more environmentally friendly than reverberatory furnaces and blast furnaces. When melting metals, they have replaced these two production methods and become a common clean production method in modern factories. The amount of heatable metal ranges from one kilogram to hundreds of metric tons. In operation, the induction furnace will mostly have a high frequency hum, depending on its operating frequency. Metals that can be processed include iron and steel, copper, aluminum and precious metals. Because the induction furnace is a clean, non-contact process, it can be used in a vacuum or in an inert atmosphere. Some special steels or alloys are oxidized by heating in air. These alloys or steels can be produced by vacuum electric furnaces.
Induction welding
Induction welding is similar to induction furnaces, but with smaller processing methods. If ferromagnetic particles (the hysteresis of the material is generated during induction) or metal particles are added to the plastic, it can also be welded by induction welding. The gap of the pipe can also be welded in this way. The current introduced near the gap heats the material and eventually produces a high temperature that can be soldered. At this time, the materials on both sides of the gap will be close to each other and welded to the gap. The current can also be conducted to the tube with a brush, but the result is the same, the material of the gap attachment is heated and welded.
