Since humans discover how to create fire, we have not been content to only use wood to burn fire to produce heating. With the continuous development of the industrial revolution, we firstly began to use fuel oil to produce heating, and then when electricity is invented latterly, we start to produce heating by using electricity. Nowadays, there is a new modern method of heating for industrial usage-induction heating. Do you have any acknowledge of induction heating? If not, let us briefly introduce to you what induction heating is and how does induction heating works.

What is induction heating?

Induction heating is a process of heating an electrically conducting object (metals or other conductive materials), through heat generated in the object by eddy currents. In short, induction heating is used to bond, harden or soften metals. For many modern manufacturing processes, induction heating offers an attractive combination of speed, consistency, and control. So on the basis of the magnetic field induction principle, an induction heating machine is widely applicable and suitable for various kinds of the metal material workpiece in many different sizes and shapes. It is mainly used applied to melting, annealing, quenching, welding, heating, brazing, forging, surface hardening, thermal forming, and other heat treatments.

What makes this heating method so unique? Normally in the most common and traditional heating methods, a torch or open flame is directly applied to the metal part. But with induction heating, heat is actually “induced” within the part itself by circulating electrical currents. As heat is transferred to the product via electromagnetic waves, the part never comes into any direct contact with any flame, the inductor itself also does not get hot (see the following picture), and there is no product contamination. When properly set up, the process becomes very repeatable and controllable.

Kexin Electronic Instrument Co., Ltd., located in Liushi, China”s low-voltage electrical appliances, adjacent to the scenic Yandang Mountain, is a tourist attraction. The company specializes in the production of the KX-5188 series tooling repair machine, high-frequency induction heating equipment, automatic ultrasonic polishing machine, etc.
