Description

CX-GF…/…VT series are vertical top loading batch type induction heating furnaces with cylindrical hot zone shape. Vertical loading, convenient for temperature measurement and aiming. The Cylindrical working chamber has higher heating efficiency.

Maximum operating temperature of 3000°C used for high-temperature graphitization of various powdered carbon and graphite materials. A cylindrical furnace chamber is especially suitable for the high-temperature treatment of powder and rolls. This furnace type is widely used in the graphitization process of polyimide thermal conductive graphite sheets (PI graphite sheet).

These furnaces use medium frequency induction heating method. A water cooled induction coil installed inside the furnace. At the center of the coil, there is a graphite crucible as the susceptor for the induction current, surrounded by carbon felt as the insulation material.
