Some Basic Knowledge About Electromagnetic heaters (I)

Electromagnetic heater is the most widely used heating method in industrial and civil fields today. Using electromagnetic heating technology, electromagnetic induction heating technology is referred to as IH (Induction Heating) technology, which is developed on the basis of Faraday’s induction law and is an application form of Faraday’s induction law.

Its essence is to use electromagnetic induction to generate eddy currents in the column to electrically heat the heating workpiece. It converts electrical energy into electromagnetic energy, and then converts electromagnetic energy into electrical energy. Electrical energy is converted into heat energy inside the metal to achieve the purpose of heating the metal. So as to eliminate the harm and interference of open flame in the heating process, it is an environmentally friendly, state-advocated heating scheme.

An electromagnetic heater is a device that uses the principle of electromagnetic induction to convert electrical energy into heat energy. The electromagnetic controller converts the alternating current into direct current through the rectifier circuit, and then converts the direct current into voltage of different frequencies through the control circuit. When the alternating magnetic field lines in the magnetic field pass through the magnetic permeable metal (iron, cobalt, nickel) materials, countless small eddy currents will be generated in the metal body, so that the metal material itself heats itself at high speed, so as to achieve the purpose of heating the metal material.
