摘要

Process for continuously graphitizing cathode blocks comprises using a tunnel-like oven with a conveying device and passing the material through a lock at the inlet and outlet of the oven. The inside of the oven has a heating path whose length is longer than the body to be graphitized and whose heating performance changes following the movement of the body. Preferably the heating path is a conductive heating system whose introduction gaps are less than the length of the body to be graphitized, or the heating path is an inductive heating system or is a combination of the two types of heating system.
