Principle of electromagnetic induction heater, what is electromagnetic induction heater

In our life, with the advancement of technology, power is very important to us, and we use power all the time. It is transformed into the energy we need through various transformations, so what is the principle of electromagnetic induction heaters? What is What about electromagnetic induction heaters? Below we will share with you Kehua. Electromagnetic induction heater Electromagnetic induction heater: A heating controller based on the principle of electromagnetic induction heating. Electromagnetic induction heating originates from the phenomenon of electromagnetic induction discovered by Faraday, that is, an alternating magnetic field induces an electric current in a conductor, which causes the conductor to heat up. Since the discovery of the heating effect of electric current through wires, there have been many inventors in the world engaged in research and manufacture of electric heaters. In 1890, Swedish technicians invented the first induction Induction melting furnace, a slotted core furnace; in 1893, the prototype of an electric iron appeared in the United States; in 1909, the emergence of an electric stove realized the process of converting electrical energy into heat energy; In 1916, the Americans invented the closed-groove cored furnace, and the electromagnetic induction technology gradually entered the practical stage. Principle of electromagnetic induction heater Heating principle The principle of electromagnetic induction heating is that the alternating current generated by the induction heating power supply generates an alternating magnetic field through the inductor (ie the coil), and the magnetic conductive object is placed in it to cut the alternating magnetic field lines, thereby generating alternating magnetic lines inside the object. The variable current (ie eddy current), the eddy current causes the atoms inside the object to move at high speed and irregularly, and the atoms collide and rub against each other to generate heat energy, which has the effect of heating the object. It is a heating method that converts electrical energy into magnetic energy, so that the heated steel body induces magnetic energy to generate heat. In this way, it fundamentally solves the problem of inefficiency of resistive heating by means of heat conduction such as electric heating sheets and electric heating coils. Principle Advantages of Electromagnetic Induction Heater 1. High efficiency, energy saving and rapid heating. The internal heat heating method is adopted, that is, the metal tube inside the barrel is heated by itself through electromagnetic induction. The average preheating time is shortened by 2/3 compared with the resistance coil heating method, and the thermal efficiency is as high as 95%. Above, the power saving effect can reach 30%-70%. 2. Reduce production costs and improve product quality The heating part adopts a special cable structure, which does not generate heat itself, can withstand temperatures above 500 ℃, and has a service life of more than 5 years, and there is basically no maintenance cost in the later period. Because electromagnetic heating makes the barrel automatically heat through electromagnetic induction, the heat utilization rate is as high as 95%, which can fully and evenly heat the raw materials, thereby improving product quality 3. Reliable operation, controllable and adjustable The host adopts the most advanced industrial Using the machine board, microelectronic control, multi-channel intelligent closed-loop system and perfect protection function, effectively avoid the aging phenomenon of the host, and can fully ensure the long-term safe and stable operation of the equipment. 4. Improve the working environment The surface of the equipment is at room temperature and the human body can touch it, which greatly improves the working environment at the production site, effectively increases the enthusiasm of workers for production, and reduces the cost of traditional cooling facilities.
