Induction heating is not a new idea, it was originally conceived back in the 19th century by a scientist call Michael Faraday when he connected two copper wires to a battery and noticed a reverse flow of current in one of the wires. Since then they have gone through many changes but are still running on the basic principles discovered and noted by Faraday almost 200 years ago. It is a great discovery which apply life all over the world.
Like the Induction heat treatment furnace It seems complicated when tell out by words, let's try. An induction heater is exactly what it claims to be. It is a heating unit that works but utilizing powerful magnetic fields to heat a conductive body. There are three main components to an induction heater, the primary part being the coil. The coil is actually composed of many smaller coils - copper coils - wrapped around and around each other, and a central mandrel (a rod whose purpose is to be coiled by other metals and to keep them in the desired shape). The coil is the inductive unit, transferring the heat through from the power source to the working surface.
The power unit is of course the generator, the article that all induction heaters depend on, Taking in the power from the mains supply is the purpose, and increase it to an average anywhere between 2-500 kW. The final component of any induction heater is the working surface or work head. This is simply an area of capacitors and transformers whose job it is to link the power from the other two units and allow the heater to function correctly.
They usually work on one of two frequencies known in the business as RF and MF induction. The difference between the two is simply power. RF induction works between 100 kHz and 10 MHz, RF style heaters are used for smaller items and heating needs, while the MF Induction heater(s) work on a range anywhere between 1 kHz and 10 kHz and are, as a normal rule of thumb used on larger components.
The treatment is considered to be effective depending on the modification properties of the surface materials like the residual stress that is introduced. Induction hardening is one of the most common processes used in improving the durability of components. It turns the work piece into a tough core that has tensile residual stress and a hard layer with compressive stress on the surface. This process has proved to be very effective when it comes to extending the life and resistance of the component.
