It indirectly heats the carbon material in a fixed material tank to complete the calcination process of the carbon material. When the carbon material is calcined, when the temperature of the raw material reaches 350~600℃, a large amount of volatile matter in the raw material is released, which is collected through the volatile channel and sent to the fire channel for combustion. After the raw material is subjected to a high temperature of more than 1200~1300℃ and completes a series of physical and chemical reactions, it is discharged from the lower hopper at the bottom of the material tank. The number of tanks for the pot furnace includes 6-pot furnace, 12-pot furnace, 16-pot furnace, 32-pot furnace and other furnace types.
