Description

Technical Field

[0001] The utility model relates to a graphitization furnace, in particular to a temperature monitoring device for a graphitization furnace. Background Art

[0002] The graphitization furnace is a high-temperature processing equipment, which is mainly used for the sintering and graphitization of carbon materials, graphitization of PI films, graphitization of thermal conductive materials, sintering of carbon fiber ropes, sintering and graphitization of carbon fiber filaments, purification of graphite powder and other processes. Its operating temperature is as high as 3000℃, with high production efficiency and energy saving. The graphitization furnace is equipped with an online temperature measurement and temperature control system, which can monitor the temperature in the furnace in real time and adjust it automatically.
