The principle of electromagnetic induction heating is that the alternating current generated by the induction heating power supply passes through the inductor (i.e. coil) to generate an alternating magnetic field. A magnetic object is placed inside it to cut the alternating magnetic field lines, thereby generating alternating current (i.e. eddy current) inside the object. The eddy current causes the atoms inside the object to move at high speed and irregularly, causing them to collide and friction with each other, generating heat energy, thereby heating the object. It is a heating method that converts electrical energy into magnetic energy, causing the heated steel body to sense magnetic energy and generate heat
■The advantages of electromagnetic heating
1. Efficient and energy-saving, fast heating adopts internal heating method, which uses electromagnetic induction to heat the metal pipes inside the material barrel. The average preheating time is shortened by 2/3 compared to the resistance coil heating method, and the thermal efficiency is over 95%, with a power saving effect of 30% -70%.
2. Reduce production costs and improve product quality. The heating part adopts a special cable structure, which does not generate heat and can withstand temperatures above 500 ℃. The service life can reach more than 5 years, and there is basically no maintenance cost in the later stage.
3． The reliable and controllable operation of the host adopts the current advanced industrial machine board, microelectronic control, multi-channel intelligent closed-loop system, and complete protection functions, effectively avoiding the aging phenomenon of the host and fully ensuring 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 can be touched by the human body, greatly improving the working environment of the production site, effectively increasing workers' enthusiasm for production, and reducing the cost of traditional cooling facilities.
