Product Description

China graphite electrodes 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, the production period of ultra high power graphite electrodes is more than 70 days, and the production period of graphite electrode joints (nipples) requiring multiple impregnation is more longer.

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.
