How induction heating equipment converts electrical energy into magnetic energy to heat metal

Induction heating equipment is a heating device based on the principle of electromagnetic induction heating. It converts electric energy into magnetic energy, and then heats the heated metal to induce magnetic energy. If interested, it will come with Haituo Electromechanical Xiaobian. Understand it!


Induction heating equipment

Induction heating device (Electromagnetic induction heater): A heating controller based on the principle of electromagnetic induction heating. Electromagnetic induction heating is derived from the electromagnetic induction phenomenon found by Faraday, that is, the alternating magnetic field generates an induced current in the conductor, which causes the conductor to generate heat. Since the discovery of the thermal effects of current through the wires, many inventors have been working in the world to research and manufacture electric heaters. In 1890, Swedish technicians invented the first induction melting furnace, the slotted cored furnace; in 1893, the United States appeared the prototype of the electric iron; in 1909, the appearance of the electric stove realized the process of converting electricity into heat; In 1916, the Americans invented the closed-cell cored furnace, and the electromagnetic induction technology gradually entered the practical stage.
 
 

Electromagnetic induction heating equipment heating principle

The principle of electromagnetic induction heating is that the alternating current generated by the induction heating power source generates an alternating magnetic field through the inductor (ie, the coil), and the magnetic conductive object is placed therein to cut the alternating magnetic field lines, thereby generating an alternating current (ie, eddy current) inside the object. The eddy current causes the atoms inside the object to move at a high speed and irregularly, and the atoms collide with each other and friction to generate heat energy, thereby heating the article. That is, a heating method in which electric energy is converted into magnetic energy to cause the heated steel body to induce magnetic energy and generate heat. In this way, it fundamentally solves the problem of low efficiency of heating by means of heat conduction such as electric heating sheets and electric heating coils.


Advantages of electromagnetic induction heating equipment

1. High-efficiency, energy-saving and rapid heating adopt internal heat heating method, that is, the metal tube inside the barrel is self-heated by electromagnetic induction, and the average preheating time is shortened by 2/3 compared with the heating method of the resistance ring, and the thermal efficiency is as high as 95% or more, and the power saving effect can be Up to 30%-70%.

2. Reduce production cost and improve product quality. The heating part adopts special cable structure, which does not generate heat itself. It can withstand temperatures above 500 °C, and the service life can reach more than 5 years. There is basically no maintenance cost in the later period. Because electromagnetic heating is to automatically heat the barrel through electromagnetic induction, the heat utilization rate is over 95%, which can fully and uniformly heat the raw materials, thereby improving product quality.

3. The reliable and controllable adjustable host adopts the most advanced industrial machine board, microelectronic control, multi-channel intelligent closed-loop system and perfect protection function, which effectively avoids the aging phenomenon of the host and fully guarantees the long-term safety and stability of the equipment. Run.
