380120kw Electromagnetic Heating Coil
Original heating coil: It heats the barrel through heat conduction, radiation, and convection. The Joule heat generated by resistance R (Joule heat is the thermal vibration energy emitted due to atomic collisions when electrons move in the resistor) → passes through insulating material → to the heating coil shell → transfers heat to the barrel. After electrical energy is converted into heat, the usable thermal energy conducted and radiated to the barrel is less than 40%, resulting in a large amount of electrical energy waste and also deteriorating the working environment of the workshop.
Traditional heating mode: 50% of the thermal energy is dissipated into the air
2. Electromagnetic heating coil: It uses power electronics technology and electromagnetic compatibility technology to rectify, filter, and invert the 220V AC power supply into a high-frequency alternating current of 25-30KHZ. This converts the high-frequency alternating current into a high-frequency alternating magnetic field. When the magnetic field encounters the metal barrel, it
