About Induction Heating
Can I heat a very long workpiece with induction?
There are trade-offs when using long coils.
Yes, but when the length of the coil exceeds 4x to 8x its diameter, uniform heating at high power densities becomes difficult. In these instances, single-turn or multiple-turn coils that scan the length of the workpiece are often preferable.
