Description:

The electric arc furnace offers an alternative method ofbulk steel making. Unlike the basic oxygen route,the electric arc furnace does not use hot metal. It is charged with "cold" material which is normally steel scrap - which would otherwise be unsightly and environmentally damaging. Other forms of raw material are also available.

Steel scrap is firsttipped intothe electric arc furnace froman overhead crane. A lid is then swung into position over the electric arc furnace. This lid containsthree graphite electrodeswhich arelowered into the electric arc furnace. An electric current is passed through the electrodes to form an arc. The heat generated by this arc melts the scrap.

During the melting process, other metals (ferro-alloys) are added to the steel to give it therequired chemical composition.Meanwhile,oxygen is blown in to the electric arc furnace to purify the steel.

After samples have been taken to check thechemical composition of the steel, the electric arc furnace is tilted to allow theslag, which is floating on the surface of themolten steel, to be poured off. The electric arc furnace is then tilted in the other direction and the molten steel poured into a ladle, where it either undergoes secondary steelmaking or is transported to the caster.

Basic Configuration:
