Electromagnetic Induction Furnaces Definition
Electromagnetic induction furnaces definition is an industrial furnace that uses the principle of electromagnetic induction to melt metal.
It's divided into two types: induction melting furnace & induction heating equipment.
The former is used for smelting or heat preservation of materials, and the charge is finally in a liquid state; The latter is used for heating materials, including overall uniform heating, surface heating or local heating of materials.
According to the AC power used, the electromagnetic induction furnace is defined as three types: power frequency (50 Hz or 60 Hz), intermediate frequency (60-10000 Hz) & high frequency (higher than 10000 Hz). Among them, the intermediate frequency furnace is more demanded by steel mills.
Features & Principles
If you want to know more about electromagnetic induction furnaces definition, will need to further understand the characteristics and working principle of induction furnace.
Features
(1) Fast heating speed, high production efficiency, less oxidation and decarburization, saving material and forging mold costs Crucible-type high-frequency induction furnace.
Since the principle of intermediate frequency induction heating is electromagnetic induction, the heat is generated in the workpiece itself. Ordinary workers can continue the forging task ten minutes after going to work with the intermediate frequency electric furnace, and there is no need for professional workers to burn the furnace and seal the furnace in advance. . There is no need to worry about the waste of billets heated by coal furnaces caused by power outages or equipment failures.
This heating method heats evenly, and the temperature difference between the core and the surface is extremely small, so the life of the forging die is greatly increased in forging, and the surface roughness of the forging is also less than 50um.
(2) The working environment is superior, improving the working environment of workers and the image of the company, no pollution, and low energy consumption.
The working environment of the workers has been greatly improved. During the working period, the furnace can meet the requirements of various indicators of the environmental protection department, which has further established an external image for the company and a better development trend in the forging industry in the future.
(3) Uniform heating, extremely small temperature difference between core and surface, and high temperature control accuracy.
Induction heating generates heat in the workpiece itself, so the heating is uniform and the temperature difference between the core and the surface is extremely small. The application of temperature control system can realize precise control of temperature and improve product quality and pass rate.
Working principle
Electromagnetic induction heating uses magnetic field coupling to heat the crucible itself in a non-contact manner, thereby melting the metal in the crucible and achieving an electrothermal conversion rate of more than 95%. The crucible is generally made of magnetic materials such as iron and graphite.
Induction heating furnace is a heating furnace that uses the principle of electromagnetic induction to heat metal. It is widely used in high-temperature heating and low-temperature heating, forging industry, foundry industry and metal quenching and tempering heating in high-temperature heating, anti-corrosion spraying preheating of steel pipes in low-temperature heating, induction heating The furnace has become an indispensable heating equipment.
The multifunctional microcomputer electromagnetic induction heating controller adopts the principle of electromagnetic induction heating to convert electrical energy into heat energy. First, the 50Hz alternating current is converted into direct current through the internal rectification and filtering circuit, and then the direct current is converted into high-frequency high-voltage power with a frequency of 17-30KHz through the PFM control circuit. The high-speed changing current passing through the coil will generate a high-speed changing magnetic field. When the magnetic lines of force inside pass through the heated metal object, countless small eddy currents will be generated in the heated metal object, so that the heated metal object itself heats up at a high speed.
The electromagnetic induction furnaces definition is introduced here for all friends.
