Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrodes, in particular to a graphite electrode with a joint. 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 (abbreviated as graphite electrode), to distinguish it from natural graphite electrode made of natural graphite as raw material. The existing graphite electrode is usually wrapped around the graphite electrode when connected to the external wire, resulting in poor connection stability with the graphite electrode and the wire is easy to fall off. For this reason, we propose a graphite electrode with a joint. Utility Model Content

[0008] Specifically, the protective mechanism is composed of a protective layer, a barrier layer and an insulating layer. The outer wall of the graphite electrode body is connected with the protective layer, the layer wall of the protective layer is connected with the barrier layer, and the outer wall of the barrier layer is connected with the insulating layer.

[0009] By adopting the above technical scheme, when the graphite electrode body is protected, since the outer wall of the graphite electrode body is connected with a protective mechanism, the protective mechanism is composed of a protective layer, a barrier layer and an insulating layer. The outside of the graphite electrode body is sleeved with an insulating layer, and the insulating layer is made of an insulating rubber material, which has good insulation properties.
