The different and structure of HP graphite electrode

HP Graphite electrodes are used mainly in electric arc furnace steel production. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.

GrafTech International introduced UCAR Grade AGX ultra-high power (UHP) graphite electrodes and Grade AGX supersize graphite electrodes, 700 to 750 mm in diameter. Now GrafTech International offers unique Grade ALX pinless graphite electrodes to address the issues of stub losses and poor bottom joint performance, Grade LFX premium quality electrodes designed and engineered specifically for the ladle furnaces and non-steel applications.

Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.

The HP graphite 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.
