High frequency heating machine coil - has the effect of electromagnetic induction

High-frequency heating coil high-frequency heating, that is, induction heating is a method of heating electrical conductors (usually metals) using electromagnetic induction, which will generate eddy currents in the metal, and cause Joule heating of the metal due to resistance. Induction heaters include an electromagnet through which high-frequency alternating current is passed. If the object has a large magnetic permeability, it may also generate heat due to the loss of magnetic hysteresis. The AC frequency used depends on the size of the item to be heated, the type of metal, the degree of coupling between the heating coil and the item to be heated, and the depth of penetration. The following Kehua will introduce its performance: High-frequency heating machine coil Application 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, and magnetic materials will experience 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. Induction furnaces Induction furnaces use induction to melt metals. After melting, the high-frequency magnetic field can also agitate the metal, ensuring that the added metal is fully mixed with the original metal when making alloys. Most induction furnaces consist of a water-cooled copper ring encased in a heat-resistant material. 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 clean production method commonly used in modern factories. The amount of heatable metal varies from one kilogram to hundreds of metric tons. During operation, induction furnaces are likely to have a high-frequency humming sound, which varies according to their operating frequency. Metals that can be processed include iron and steel, copper, aluminum and precious metals. Because induction furnaces are clean, non-contact processes, they can be used in vacuum or in an inert gas environment. Some special steels or alloys are oxidized when heated in air, and such alloys or steels can be produced by vacuum electric furnaces. Induction welding Induction welding is a processing method similar to an induction furnace, but on a smaller scale. If ferromagnetic particles (the characteristic of hysteresis in the material generates heat during induction) or metal particles are added to the plastic, induction welding can also be used for welding. The gaps of pipe fittings can also be welded in this way. The electric current introduced near the gap heats the material, resulting in a high temperature that can be welded. At this time, the materials on both sides of the gap will be forced to approach each other, and the gap will be welded. Electricity can also be conducted into the pipe with a brush, but the result is the same, the material of the gap attachment heats up and welds. Induction cooker In the induction cooker, the induction coil heats the iron bottom of the cookware, and the cookware of copper, aluminum or other non-ferrous materials cannot be used with the induction cooker. When the induction cooker is heating, the heat from the bottom of the pot will be transferred to the food by thermal conduction. The benefits of an induction cooker are efficiency, safety and speed. Induction cookers are either stationary or mobile. Induction Brazing Induction brazing is typically used in high-volume production processes to produce consistent results with a high degree of repeatability. Induction sealing Induction sealing is used in the food and pharmaceutical industries. A piece of aluminum foil is placed at the opening of a bottle or jar and heated by induction to make it tightly sealed to the container. This creates a seal against changing the contents, which would require breaking the foil. High-frequency heating machine coil The high-frequency heating machine coil is a device that we can also touch in our lives. Kehua also briefly introduces its functions and applications above. Hope it helps a little bit.
