Description

TECHNICAL FIELD

[0001] The utility model relates to sintering furnace technical field, concretely is a kind of sintering furnace for graphite production. BACKGROUND

[0002] Graphite sintering furnace is converted into heat energy by electric current, and high-purity graphite electrode is used as heating element. Because graphite electrode has good conductivity and high-temperature resistance, it can work stably in high-temperature environment. When electric current passes through graphite electrode, a large amount of heat is generated, thereby heating the raw materials in the furnace. In the high-temperature and high-pressure environment, the binding force between the particles of the raw materials is enhanced, forming a solid crystalline body, completing the sintering process. The existing sintering furnace is generally of a closed structure and cannot observe the sintering process. In the sintering process, the sintering effect may be poor due to temperature and pressure differences. Therefore, a sintering furnace that can observe the sintering process in real time is needed to adjust the temperature or pressure in real time, reduce the rate of defective products, and thus a sintering furnace for graphite production is proposed to solve the above problems.
