ØDescription：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 (***0 °C) that converts carbon to graphite. They can
vary in size up to *1 ft. long and *0 in. in
diameter.
ØUsage: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
