Graphite electrode and preparation process thereof

Abstract

The invention relates to the field of electrodes, in particular to a graphite electrode and a preparation process thereof, and the process comprises the following steps: S1, a first extrusion bottom plate, a plurality of first disc bodies and a first extrusion top plate are fixed to form a first graphite electrode; s2, a second extrusion bottom plate, a plurality of second disc bodies, a reaming disc, a limiting disc and a second extrusion top plate are fixed to form a second graphite electrode; s3, the conversion mechanism penetrates through the first graphite electrode and extends into the second graphite electrode to form a graphite electrode; the graphite electrode comprises a first graphite electrode, a second graphite electrode and a conversion mechanism, the first graphite electrode comprises a first extrusion bottom plate, a first disc body, a first extrusion top plate, a connecting nail I and a connecting nail II; the second graphite electrode comprises a second extrusion bottom plate, a second disc body, a reaming disc, a limiting disc, a second extrusion top plate, a connecting nail III and a connecting nail IV; and the graphite electrode for off-axis conduction can be prepared.

Description

technical field [0001] The invention relates to the field of electrodes, and more particularly to a graphite electrode and a preparation process thereof. Background technique [0002] Graphite electrode refers to a kind of resistant material made of petroleum coke and pitch coke as aggregate, coal tar pitch as binder, through raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. High-temperature graphite conductive materials, called artificial graphite electrodes and referred to as graphite electrodes, are different from natural graphite electrodes prepared by using natural graphite as raw materials; the graphite electrodes in the prior art have a single structure, all of which are cylindrical in shape, and can only be used for the same Axial conduction is not applicable to off-axis conduction. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a gra...

Problems solved by technology

[0002] Graphite electrode refers to petroleum coke, pitch coke as aggregate, coal tar pitch as binder, a kind of resistant electrode made by calcination of raw materials, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. High-temperature graphite conductive material is called artificial graphite electrode or graphite electrode for short, to distinguish it from natural graphite electrodes prepared from natural graphite; graphite electrodes in the prior art have a single structure, are cylindrical, and can only be used for the Shaft conduction, not suitable for eccentric conduction
