Abstract

The application discloses a vertical continuous graphitization furnace According to this application, the electrode positive pole is located at a center of a furnace body, several graphite electrode negative poles are horizontally and axially symmetrically distributed with the electrode positive pole at the center of a heating chamber; the inner end of several graphite electrode negative poles and the arc-shaped inner wall of the heating chamber are on the same arc surface; the lower end surface of the electrode positive pole is in the same horizontal plane as the lower surface of multiple graphite electrode negative poles; the longitudinal cross-section of the heating chamber is in an inverted trapezoidal shape. This graphite furnace has the advantages of uniform temperature distribution in the high-temperature heating zone, which can ensure material consistency, temperature controllability, smooth exhaust and impurity removal, and the ability to prepare high-purity artificial graphite materials.
