OEM manufacturer Silicon Carbon Alloy - GRAPHITE ELECTRODE – COSAVE
OEM manufacturer Silicon Carbon Alloy - GRAPHITE ELECTRODE – COSAVE Detail:
Graphite electrode, mainly made of petroleum coke and needle coke, coal tar pitch as binder, is prepared by calcination, compounding, kneading, pressing, roasting, graphitization and machining, and is released in the form of electric arc in electric arc furnace. The conductor that heats and melts the charge of the electric charge can be classified into ordinary power, high power and ultra high power according to its quality index.
