Advantage
The advantage of graphite electrode is that it is easy to process, the electricity discharge processing rate is high, and the graphite loss is small.
Production characteristics
The production period is long. The production period of regular power graphite electrodes is about 45 days, and the production period of graphite electrode joints (nipples) requiring multiple impregnation is more longer.
graphite electrodes Application
Mainly used in electric arc steelmaking furnaces, refining furnaces, industrial silicon furnaces, yellow phosphorus furnaces, electric resistance furnaces, etc., as conductive usage. The graphite electrode blank is also used to process a variety of shaped graphite products such as enamel, mold, boat and heating element.
