Short Lead Time for Graphite Electrode Rp - UHP Grades Graphite Electrodes – Sungraf Detail:

Products Details

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.

Usage

01
An increasing proportion of global steel is made using electric arc furnaces
02
The electric arc furnace itself is getting more efficient and making more steel per tonne of electrode
