Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrode production, in particular to a hot forming device for graphite anode production. Background Art

[0002] Graphite electrode refers to a high-temperature resistant graphite conductive material made of petroleum coke and asphalt coke as aggregates and coal tar as binder, through raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. It is called artificial graphite electrode (referred to as graphite electrode), to distinguish it from natural graphite electrode made from natural graphite as raw material.

[0003] During the production process of graphite electrodes, they are first formed by a mold and then heated to form the corresponding graphite electrode shape. In the production process of existing graphite electrodes, the extrusion forming and heating processes are mostly divided into two parts, that is, the production and processing are carried out in a paradigm of forming and then heating and forming. This method leads to low efficiency at the beginning of the production process and the inability to ensure the smooth surface of the graphite electrode, which in turn affects the quality of the graphite electrode.
