1. A graphitization apparatus for manufacturing artificial graphite using lasers, comprising:
a first chamber having doors located on both walls thereof in such a way as to be open when saggars go in and out and providing a workspace for graphitization of raw materials filled in the saggars;
a laser heater consisting of a plurality of laser systems and irradiating laser beams onto the raw materials introduced into the first chamber to graphitize the raw materials; and
a first transfer conveyor for sending the saggars filled with the raw materials to the first chamber and taking the saggars out of the first camber after the graphitization has been completed,
wherein a laser scanner is fixedly located and operates an optical lens so that a point, a line, and a surface light sources move on the top of a corresponding saggar at a speed in a range of 1 mm/s to 10 m/s,
wherein a first dedicated laser head makes use of the surface light source and is movable in a three-axis direction.
