HP UHP graphite electrode
Materials for making graphite electrodes are of petroleum coke, pitch coke.
Full sets of process operation from material calcination, crushing, screening, kneading, shaping,
baking, impregnating, graphitizing, machining&finishing, to the final inspection are fulfilled
within our own capabilities and facilities under stringent and precise production process. OEM
service offered. Customers' needs can be well fully satisfied.
Functions: Graphite electrodes are used in steel making with electric furnace, or with submerged arc furnaces to smelt ferroalloy, or wth resistance furnace. Through graphite electrode, electric current are introduced and produces electrical arc in smelting surrendings. When temperature reaches 2000 degree, smelting begins. The above mentioned electrodes are applied for coomon E-furnace and high power E-furnace with high voltage and short electric arc.
Advantages: Low sulgur high density; Extraordinary performance in heat conductivity and anti-oxidation. Low consumption rate in quantity and power loss during smelting. Low resistivity but high bending&compressive strength.
