Product Description

RP Graphite Electrode For Steel-Making 
Model Number:RP
Resistance (μΩ.m):≤ 8.5
Apparent Density (g/cm³ ):

Description: The electrodes carry the electricity that heats electric arc furnaces, the vast majority steel furnaces. They are made from petroleum coke after it is mixed with petroleum pitch, extruded and shaped, then baked to sinter it, and then graphitized by heating it above the temperature (3000 °C) that converts carbon to graphite. They can vary in size up to 11 ft. long and 30 in. in diameter.
