DESCRIPTION:
Graphite electrode, mainly made of high-quality petroleum coke and needle coke, coal tar pitch as binder, is prepared by calcination, compounding, kneading, pressing, roasting, graphitization and machining. According to the quality, it can be divided into regular power, high power and ultra-high power.
FEATURE:
Has good electrical conductivity
Strong thermal shock resistance
High mechanical strength.
APPLICATION:
Ultra-high-power graphite electrode, mainly used in ultra-high power steelmaking electric arc furnace (EAF).
High power graphite electrode, mainly used in high power electric arc furnace for steel making.
Regular power graphite electrode, mainly used in ordinary power electric furnace for steel making, silicon refining, yellow phosphorus and so on.
