Preventing Power Loss during Induction Hardening

Preventing power loss during induction hardening is one of the primary advantages of using induction furnaces to perform this work. The design of electrical circuit and coil, in addition to the shape or turn numbers of the coil are factors which determine the operating performance of the induction hardening process.

Preventing Power Loss during Induction HardeningThe induction hardening process involves rapid heating of materials by electromagnetic induction and hysteretic heat loss. Because the frequency of heating currents is concentrated very close to the surface of the metal to be hardened, the electric current is confined to a limited area, with hardening occurring as a result of proximity. This proximity provides for minimal heat loss, which translates to minimal power loss during the process.

The resonating invertor also contributes to power savings, because it contains an inverter impedance matching system. This allows the resistance of the coil, tank capacitor and work piece to combine into a single loss resistance, which means this is the only thing consuming power, and therefore creates an efficient system of power usage.

The benefits of preventing power loss during induction hardening process include the savings in energy, materials loss and monetary savings. This is by far the most efficient way to accomplish the task of hardening, and manufacturers and industries world-wide are converting to induction technology in order to reap these benefits.

Recent economic problems prevalent on a world-wide basis have placed all types of metal industries in danger of no longer being able to cover the cost of operations. Induction heating and hardening have successfully provided an option which allows industry to potentially realize more profit than ever before.
