In susceptor heating we use induction to heat a primary material (metal or a conductive material), which then heats a secondary material by conduction or radiation.
The susceptor can be made from graphite, aluminum, carbon steel, copper, stainless steel, or other similar metals. The primary purpose of the susceptor is to provide a heat source for the secondary material.
When the susceptor is heated with induction, the surface of the susceptor reaches a high temperature, and the temperature is then transferred to the secondary material through conduction or radiation.
A critical factor in the operation of an induction susceptor heating system is the power transfer in the system. This power transfer is affected by the size of the susceptor, the distance between the susceptor and the coil, the material type used for the susceptor, and the size of the secondary material.
It’s important to know how the power transfer works because it can affect the heating process. When the power transfer is too high, the secondary material may be overheated. If the power transfer is too low, the heating process may be too slow.
In order to get the best performance out of an induction heating system, you need to be able to control the power transfer in the system. This is because the power transfer has a direct impact on the heating process.
