Arc Furnace Regular Power RP Graphite Electrode 250-1400mm For Steelmaking
The advantages of regular power graphite electrodes in steelmaking lie in their cost-effectiveness, stability, and suitability for use in small to medium-scale steel production
Graphite electrode brief introduction
Graphite electrode, also known as artificial graphite electrode, is based on petroleum coke and needle coke as the main raw materials, and coal pitch as the binder. After calcining, grinding, mixing and kneading, extrusion forming, roasting, asphalt impregnation, graphitization, machining and other series.A high temperature resistant graphite conductive material produced by the process.Our products have the following characteristics: low electric resistivity, good electrical and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, and high machining accuracy.

The Causes of Electrode Breakage
When the electrode is stressed, the degree of force decreases progressively from the top to bottom. The maximum stress is on the joint of electrode and nipple under the holder.
When the electrode is subjected to external force: The external force of stress concentration > the strength of the electrode, and this will lead to the damage of the electrode.
The causes of external force: the collapse of the big charging materials during the melting period, the non-conducting objects exist at the bottom of the electrode in the scrap steel, the impact of the nubby flowing steel.
The causes of breakage:the incongruous response speed of the lifters, the deviated electrode the furnace cover holes from the core, the gaps between the joint of electrode and nipple and the unsubstandard nipples.
Poor machining accuracy of electrodes and joints will also cause poor coordination and joint breakage.
