Embodiment Construction
[0041] The carbon atoms of carbonaceous materials are arranged irregularly. Only through high-temperature heat treatment at 2200°C to 2600°C can the carbon atoms be recrystallized and rearranged in an orderly manner to present the crystal structure of graphite, which has many excellent properties of graphite. Such as significantly improved electrical and thermal conductivity, better chemical and thermal stability, reduced impurities, lower hardness, easier machining, and more. The function of the graphitization furnace is to convert carbonaceous materials into artificial graphite materials, such as graphite materials that provide high-quality carbon elements for iron and steel smelting, aluminum smelting, negative electrode materials, other non-ferrous metal industries, and nuclear industries. In the prior art, the graphitization furnace is provided with an upper electrode and a lower electrode, and an umbrella-shaped electric field or a frustum-shaped electric field with a low...
