This benefit of eddy currents can not only cook a meal; it can melt steel and different metals.
Let’s address “the elephant in the room,” that induction heating depends on the existence of eddy currents. Briefly, when a changing magnetic field passes via any conductive object, current flow is generated in the object. That current discharge creates a secondary electric field in the conductor. The secondary electric field then produces another flow of current known as the eddy current because it flows in a circular pattern, much like water can stir in a slow-moving stream when it encounters an obstacle. The push-pull between these fields is the reason for kinetic energy caused by electrons being shuttled back and forth—producing heat in the conductor.
Applications of Induction Heating Machines
Induction heating is utilized to manufacture end items as various as bulldozers, faucets, and sealing plastic lids on pharmaceutical bottles. The fundamental design of an induction heating machine uses a coil of wire and an AC to induce a changing magnetic field in the item to be heated—the workpiece. The ring can measure only a few centimeters in diameter or any other dimension suited to the job at hand.
The workpiece is placed within the magnetic field generated by the coil but not in contact with it. They are then heated to the desired level by the eddy currents. Relying upon the heated material, temperatures as high as 2,200° F (1,200° C) can be achieved.
Induction heating is clean and needs no fossil fuels. Parts revealed to induction heating simply heat up, so there’s no cleanup afterward and no apprehension about contamination of the workpiece. It’s also fast; for example, manufacturers of pipes and tubular channels use induction heating to weld a seam along the longitudinal dimension of pipes passing by at high speed on a conveyor.
Here are a few more examples where induction heating can be utilized:
- Induction hardening and tempering alter the physical aspects of materials to meet the requirements of diverse applications.
- Induction melting can be utilized to melt ferrous or non-ferrous metal containing nuclear material and different alloys used in medicine and dentistry.
- Heat heating can bond metal and carbon fiber materials, curing adhesives between two textures.
- Soldering and welding are all natural applications for induction heating where accurate temperature management and accurately confining heat to the desired area are essential.
Let’s see some outstanding benefits of Induction heating:
- It is appropriate for routine operations.
- The heating of the material is carried out without direct contact with the energy supply.
- There is no noise, dirt, or smoke in its process; thus, the working circumstances are enjoyable.
- Flexible temperature command and heat transfer can be highly closely monitored.
- In significantly less time, it reaches the melting point.
- It has dramatically heightened constant and accurate heating.
- For the construction of high-grade alloys, induction heating is perfect.
- Technological advancements made the induction heating method a valuable tool in the industry of heat treatment plants.
- This method is more accurate for the surface hardening of metals and non-ferrous metals.
- Automatic temperature commands can be done with the help of timers and response systems.
- In the process of induction heating, any side product does not release.
- For induction heating, no such skilled laborers are needed; thus, the operating costs are also reduced.
