RP400x2100mmGraphite electrode has the advantages of low resistivity,high electrical conductivity and thermal conductivity,good oxidation resistance, good thermal shock resistance,high mechanical strength,easy to machine,etc.1. Low electric resistance 2. Good electric and thermal conductivity 3. High density 4. High anti-oxidation capability 5. High mechanical strength 6. High machining accuracyGrades Available: RP, HP, SHP, UHP graphite electrodes and nipples.Special Treatment: Anti-oxidation impregnation treatment to prolong graphite electrodes service life and reduce consumption rate.

The graphite electrode is mainly made of petroleum coke and needle coke, and the coal bitumen is used as a binder. It is made by calcination, compounding, kneading, forming, baking, graphitization and machining.

According to its quality indicators, graphite electrodes can be divided into RP graphite electrodes, HP graphite electrodes and UHP graphite electrodes. HP grade graphite electrode add 30% Japan needle coke, UHP grade graphite electrode use 100% needle coke. Widely used in LF, EAF for steel making industry, Non-ferrous industry, silicon and phosphorus industry.
