Description

Technical Field

[0001] The utility model relates to a graphite electrode joint plug production device, in particular to a graphite electrode joint plug forming device. Background Art

[0002] The graphite electrode joint plug is used in the joint plug hole of the graphite electrode joint. After the graphite electrode rod and the graphite electrode joint are fixed by tapered threads, during arc steelmaking, the joint plug is heated and expanded, and the melted fluid material fills the thread gap and then solidifies, preventing the graphite electrode and the graphite electrode joint from loosening.

[0003] The graphite electrode joint plug is usually a cylinder, which is formed by pressing a joint plug mold and adding mixed graphite powder, coke powder, asphalt and other raw materials. Therefore, a graphite electrode joint plug molding device is needed in the manufacture of the graphite electrode joint plug.
