Product Description
UHP600 Carbon Graphite Electrode for Arc Furnace
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: 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
Graphite Electrodes
Graphite electrode, mainly from the domestic petroleum coke and imported needle coke, is widely used in electric arc furnace,ladle furnace, submerged arc electric furnace for theproduction of alloy steel, metal and nonmetallic materials.
Our graphite electrodes characteristics:
*High density, high temperature resistance, high mechanical strength and strong chemical stability
*Low electrical resistivity combined with superb electrical and thermal conductivity
*High mechanical strength under high temperatures, ensuring robust performance
*High resistance to thermal shock and mechanical vibration, providing stability
*Reduced ash content, ensuring enhanced quality and purity
*According to insightful customer feedback, our electrodes used in EAF/LF delivered lower graphite electrode consumption rates per ton of steel.
