Principle of Induction Heating Equipment

Induction heating furnace, induction heating equipment


1. Principle of Induction Heating Furnace

Induction heating equipment The rectifier and inverter devices convert power-frequency AC current into medium-frequency or high-frequency alternating current. 60Hz-10kHz ), which utilizes the principle of electromagnetic induction to generate eddy currents and heat metallic materials. Its structure includes a furnace shell, an induction coil, a magnetic yoke, a furnace lining, and a cooling water system. The magnetic yoke can shield the magnetic field and reduce magnetic leakage.

2. Induction heating furnace Main uses

Induction heating furnace It is used in the through-heating treatment process for metallic materials prior to rolling, forging, extrusion, hot sintering, and pipe bending, as well as in heat treatment processes such as tempering and annealing of metallic materials.

Induction heating The equipment generally consists of components such as a medium-frequency power supply, electrothermal capacitors, and an induction furnace body. Fully automatic equipment also includes an automatic feeding and sorting device, a flat-vibration or chain-type feeding device, a pressure-roller feeding device, and an automatic temperature control system.

3. Induction heating Device Composition

Induction heating furnace It generally consists of components such as the main control cabinet, electric heating capacitors, induction furnace body, feed and discharge transmission mechanisms, and temperature-measuring equipment. In fully automatic control mode, it also includes: PLC Programmable controller, HMI Human-machine interfaces, industrial control computer systems, industrial control configuration software, and various types of sensors, etc.
