Refractory Supplies Black Graphite Electrode for Electric Arc Furnaces
Introduction of China manufacture graphite bar/graphite rod electrode/Graphite electrode products
China manufacture graphite bar/graphite rod electrode/Graphite electrode products, mainly made of petroleum coke and needle coke, coal tar pitch as binder, calcined, compounded, kneaded, pressed, calcined, graphitized, machined, 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 divided into ordinary power, high power and ultra high power according to its quality index.
Size and Shapes:
Customize according to customers provided drawings. Drawings deisgn is available.
a. Non-ferrous metal, precious metal and rare metal casting.
b. Sintering furnaces in powder metallurgy process and super hard materials production.
c. High purity, without contamination to treated substances.
d. Dense material with low porosity, ensuring long service life.
e. Polished mirror surface reduces graphite consumption speed
