Abstract
A graphitization furnace has a furnace structure including a support part within a furnace chamber, and a gate valve. The gate valve in an open state thereof after a graphitization process dumps a pack material within the furnace chamber in a state in which carbon bodies are located within the furnace chamber, and the support part catches the carbon bodies as a level of the carbon bodies lowers with a decrease in an amount of the pack material remaining within the furnace chamber.
