why graphite electrode is used for steel melter

Graphite Electrodes for Iron, Steel & Metal Production

Graphite electrodes are also consumed in the refining of steel in ladle furnaces and in other smelting processes such as production of titanium dioxide. Electrodes act as conductors of electricity in the furnace, generating sufficient heat to melt scrap metal, iron ore or other raw materials used to produce steel or other metals.

Graphite Electrode an overview ScienceDirect Topics

Graphite electrodes serve to transfer the electrical energy from the power supply to the steel melt in the EAF bath. They are typically made using premium petroleum needle coke, coal tar pitch, and some additives (Fruehan, 1998).Specification of needle coke for the manufacture of large diameter graphite electrodes is shown in Table 12.12.

Why use graphite electrodes? Advantages and defects of

The graphite electrode is used to assemble the electrode and the furnace cover into a whole, and the graphite electrode can be operated up and down. The current then passes through the electrode, forming a high-temperature arc that melts the scrap steel. The electrodes can be up to 800mm(2.5ft) in diameter and up to 2800mm(9ft) in length.
