DESCRIPTION:
Graphite Electrodes are a high temperature resistant graphite conductive refractory material used in the metallurgical industry.
Graphite Electrodes are made of petroleum coke, bituminous coke as aggregates, coal tar pitch as binders, after raw material calcination, crushing and milling, batching, kneading, molding, roasting, impregnation, graphitization and machining, which are also known as artificial graphite electrodes in order to distinguish from natural graphite electrodes made of natural graphite.
FEATURE:
Low resistivity
High temperature strength
Good thermal conductivity and electrical conductivity
Low thermal expansion coefficient
Low ash, its ash content is controlled within 0.3%.
Dense and equal structure, Low graphite electrode consumption.
Good oxidation resistance
High mechanical strength
Needle coke content accounts for 80% for UHP Grade, raw materials imported from Japan and South Korea
APPLICATION:
1. Electric arc steelmaking furnace.
2. Ladle arc refining furnace.
3. Ore-heating furnaces.
4. Resistance furnaces
