Graphite Electrodes

We are offering graphite electrodes. Graphite electrodes carry the electricity that melts scrap iron and steel (and sometimes direct-reduced iron: dri) in electric arc furnaces, the vast majority of steel furnaces. They are made from petroleum coke after it is mixed with coal tar pitch, extruded and shaped, then baked to carbonize the binder (pitch), and then graphitized by heating it to temperatures approaching 3000 °c, that converts carbon to graphite. They can vary in size up to 11 ft. Long and 30 in. In diameter. An increasing proportion of global steel is made using electric arc furnaces, and the electric arc furnace itself is getting more efficient and making more steel per tonne of electrode.
