An induction furnace is an industrial furnace that uses the principle of electromagnetic induction to melt metals. The AC power supply used in the induction furnace has three types: mains frequency (50 Hz or 60 Hz), intermediate frequency (60–10000Hz) and high frequency (higher than 10000Hz).
What is the application area of an induction furnace?
What are the classifications of induction furnaces?
What are the auxiliary devices of the induction furnace?
In addition to heating or melting in the atmosphere, the induction furnace can also be heated or melted under vacuum and a protective atmosphere such as argon and neon to meet the requirements of special quality. induction furnaces have outstanding advantages in diathermy or melting soft magnetic alloys, high-resistance alloys, platinum group alloys, heat-resistant, corrosion-resistant, wear-resistant alloys and pure metals. induction furnaces are usually divided into induction heating furnaces and melting furnaces.
An electric furnace that uses the induction current generated by the induction coil to heat the material. When heating metallic materials, place them in a crucible made of refractory material. When heating non-metallic materials, place the material in a graphite crucible. When the frequency of alternating current is increased, the frequency of the induced current increases accordingly, and the heat generated increases. The induction furnace heats up quickly, the temperature is high, the operation and control are convenient, the material is less polluted during the heating process, and the product quality can be guaranteed. It is mainly used for melting special high temperature materials, and can also be used as heating and control equipment for growing single crystals from the melt.
induction furnaces are divided into two types: core induction furnaces and coreless induction furnaces.
The core induction furnace has an iron core running through the inductor and is powered by a mains frequency power supply. It is mainly used for melting and heat preservation of various cast iron, brass, bronze, zinc and other metals. The electrical efficiency is over 90% and furnace waste can be used. Melting costs are low and the maximum furnace capacity is 270 tons.
The coreless induction furnace has no iron core going through the inductor, and is divided into power frequency induction furnace, triple frequency induction furnace, generator set intermediate frequency induction furnace, thyristor intermediate frequency induction furnace and high frequency induction furnace.
The complete equipment of medium frequency induction furnace includes power supply and electric control part, furnace body part, transmission device and water cooling.
When the alternating current flows through the induction coil, an alternating magnetic field is generated around the coil, and the conductive material in the furnace generates an induced potential under the action of the alternating magnetic field. At a certain depth, a current (eddy current) forms on the surface of the charge, which heats the charge and melts through the eddy current.
