RP Graphite electrodes


Graphite electrode is one of the most important metallurgical products, mainly used as conductive material in electric arc furnace metallurgy production. RP graphite electrodes are mainly used for ordinary power electric furnaces such as steelmaking, silicon smelting, and yellow phosphorus smelting.

Advantage

● High current carrying capacity.
● Good resistance to breakage
● High resistance to oxidation and thermal shock
● High mechanical strength, low electrical resistance
● High machining accuracy, good surface finishing

Package

The graphite electrode is packed in wooden crates, and the nipples are packed in wooden cases or pre-set in the electrodes. Electrodes would be covered with polythene sheet to protect the same from dust and moisture, and fasten with steel strips, which is good looking and firm. Proper and safe seaworthy packing, easy for forklift handling. Necessary measures would be provided to avoid possible damages to nipple threads-such as protective foam and rubber caps.
