Sigma High-Temperature Furnace Co. Limited

1. Application

Mainly applied to rapid annealing of ultra-high-temperature inorganic materials, ceramic materials, functional materials, high-melting-point oxides and high-temperature metallic materials, experiments and research of sintering and smelting of special ultra-high-temperature materials in oxidizing and vacuum atmosphere.

2. Working Principle

When the AC power is inputted into the sensor, alternating electromagnetic field forms there. When the magnetic flux of the alternating electromagnetic field passes through the special ceramic composite, closed induction current forms in the ceramic composite due to electromagnetic induction, which is known as eddy current. The eddy current intensity is in direct proportion to the level of the EMF, and is in inverse proportion to reactance of eddy-current loop. The reactance of ceramic composite is very small, so the eddy current can reach very high value. As a result, much heat is generated in the ceramic composite, and then the temperature rise following it.
