Technology Exchange
The word "Induction Heating" must be familiar to everyone, because induction heating is not only used in industry, but also common in life. For example, the induction cooker we use in our daily life uses the principle of induction heating to work. So let's talk about what is electromagnetic induction heating and the principle of heating Today.
Definition
Electromagnetic induction heating, or induction heating for short, is a method of heating conductive materials such as metallic materials. As the name suggests, induction heating is to use electromagnetic induction to generate electric current inside the heated material, and rely on the energy of these eddy currents to achieve the purpose of heating.
Principle
Induction heating is the process of converting electrical energy into thermal energy. The rectifier circuit converts alternating current into direct current, and then converts it into high-frequency electricity through the inverter circuit. When the high-frequency electricity passes through the closed coil, a magnetic field will be generated. fever.
Application
At present,Induction Heating is mainly used for Metal Thermal Processing, Heat Treatment (annealing, heat treatment, shaft Heat Treatment Preheating, Hot Assembly, Forging, Straightening and Leveling, Tempering, Preheating) Welding and Melting.
POLARIS-ETeK is an enterprise with "full digital induction heating technology" as its core, and the newly developed full digital medium and High Frequency Induction Heating Equipment adopts PLC control and IGBT inverter technology, and the four advantages of the equipment have become major The company's first choice.
Advantage
1. The heating speed is fast, and the oxidation and decarburization of the workpiece is less.
2. Uniform heating and high temperature control accuracy.
3. Low energy consumption and no pollution.
4. Low heating cost.
