介绍 Introduction to electromagnetic induction heating

Electromagnetic heating, or electromagnetic induction heating in general, is a way to warm raw materials of electrical conductors such as metal composite materials. It is mainly used for metal material heat treatment, quenching and tempering, electric welding and melting.

To put it plainly, electromagnetic induction heating is the use of electromagnetic methods to cause the inside of the heated raw materials to generate an electric current. The kinetic energy of this vortex exceeds the heating target. The basic structure of the electromagnetic induction heating system software includes electromagnetic coils, alternating current and steel parts. Depending on the other half of the heating, the electromagnetic coil can be made different. The electromagnetic coil is connected to a switching power supply. The switching power supply presents an alternating current to the electromagnetic coil. The alternating current passing through the electromagnetic coil causes an alternating electromagnetic field according to the steel piece. This electromagnetic field causes the steel piece to vortex to warm up.

Induction heating principle

Electromagnetic induction heating surface quenching uses the magnetic effect of current to cause a relatively high density of induced current on the surface of the steel. It is quickly heated to the ferrite condition, and then rapidly cooled by water to obtain the heat treatment method of the austenite mechanism. When an alternating current of a necessary frequency is generated in the coil, an alternating electromagnetic field with the same frequency as that of the current amount will be generated inside and outside the coil. Metal materials and steel parts are placed in the electromagnetic induction coil. Under the effect of electromagnetic field, the induced current in the steel part will be the same as the frequency of the electromagnetic induction coil and the orientation will be reversed. Because the induced current generates a closed control loop along the surface of the steel, it is generally called a vortex. This vortex turns electromagnetic energy into energy and rapidly warms the surface of the steel. The vortex is all over the surface of the steel, and there is basically no basis for the amount of current inside the steel. This situation is called surface effect or skin effect. Electromagnetic induction heating is to use the skin effect to rapidly heat the surface of the steel to the heat treatment temperature by means of the current heat effect. The electromagnetic induction coil is made of copper tube, and the circulating water is cooled in it. When the surface of the steel part is heated to the necessary temperature in the electromagnetic induction coil, it is immediately sprinkled with water and cooled to obtain the austenite structure on the surface.

Electromagnetic heating, commonly known as electromagnetic induction heating, is a way to warm the raw materials of electrical conductors (the key is iron). It is mainly used for metal material heat treatment, quenching and tempering, electric welding and melting.

Electromagnetic induction heating is the use of electromagnetic methods to cause the inside of the heated raw materials to generate an electric current. The kinetic energy of this vortex exceeds the purpose of the heating. The basic structure of the electromagnetic induction heating system software includes an electromagnetic coil and alternating current (single pulse direct current). When an alternating current according to a necessary frequency is used in an electromagnetic coil, an alternating electromagnetic field with the same frequency as that of the current amount will be generated inside and outside it. Metal materials and steel parts are placed in the electromagnetic induction coil. Under the effect of electromagnetic field, the induced current in the steel part will be the same as the frequency of the electromagnetic induction coil and the orientation will be reversed. Because the induced current generates a closed control loop along the surface of the steel, it is called a vortex. This vortex turns electromagnetic energy into energy and rapidly heats steel parts.
