Product Description

Graphite electrode Nipples
Model Number:HP Type: Electrode Block
Length:1800mm   Grade:HP (High Power)
Resistance (μΩ.m):≤4   Apparent Density (g/cm3 ):≥ 1.78
Thermal Expansion:≤ 1.2 Flexural Strength (N/):≥18.0
Length:  1800mm
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.
