Introduction:

The electric arc furnace offers an alternative method of bulk steel making. Unlike the basic oxygen steelmaking way,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 first charged intothe electric arc furnace froman overhead crane. The roof is then swung into position over the electric arc furnace. This lid containsthree graphite electrodeswhich arelowered into the electric arc furnace. Electric currents passe through the electrodes to form arc. The heat generated by this arc are used to melt the scrap.

During the melting process, other metals (ferro-alloys) are added to the steel to give it therequired chemical composition.Meanwhile,oxygen is injected into 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 de-slagging, 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:

• HV electrical system and 33 kv transformer,
• LV electrical control and aotomatic system,
• heating bridge and guide roller,
• water-cooled furnace roof
• roof lifting mechanism,
• roof swinging mechanism
  
• electrode up& down mechanism
• large-current system( cooper claded busbar/bus tubing and water-cooled flex power cables) ,
• hydraulic system& pneumatic system,
• ladle bottomargon blowing system,
• water-cooled system and others.
