What Is The Working Principle Of The Cast Copper Band Heater?

The working principle of the cast copper band heater is to use the alternating magnetic field to install the primary coil with more lamps and the secondary coil with fewer lamps on the same iron core. The voltage ratio between the input and output of the ceramic heating coil is equal to the ratio of the number of turns of the coil, while the energy remains unchanged. Therefore, the secondary coil generates a large current at a low voltage. For induction heaters, the bearing is the short-circuiting of the secondary coil of a single lamp, and a large current is passed under the condition of low AC voltage, which generates a lot of heat. The heater itself and the yoke are kept at room temperature. Since this heating method can induce current, the bearing will be magnetized. It is important to ensure that the bearing does not absorb metal magnetic debris during operation. FAG induction heaters have automatic demagnetization function. 

Metals are used to generate eddy currents in alternating magnetic fields to heat the body, which is usually used for metal heat treatment. The principle is that when the thick metal is in an alternating magnetic field, electromagnetic induction will generate current. After the thick metal generates an electric current, the electric current forms a spiral flow inside the metal, and the heat generated by the electric current is absorbed by the metal itself, and the metal heats up rapidly. This equipment is an energy-saving equipment for pre-heating or secondary heating of fuel oil. It is installed before the combustion equipment to achieve heating of the fuel oil before combustion, so that it can be reduced at high temperatures (105°C-150°C) The viscosity of fuel oil promotes full atomization and combustion, and finally achieves the purpose of saving energy. It is widely used for pre-heating and secondary heating of fuel oil such as heavy oil, asphalt, and clear oil.
