Putting scrap or other iron raw material in the electric arc furnace for melting into steel.

A DC arc furnace makes use of one electrode to distribute energy.

Direct Reduced Iron.  A group of processes for making iron from ore by removing the oxygen from the iron ore. No blast furnace is needed.

The period when the electric arc furnace begins to pour molten steel until it finishes pouring molten steel.

A furnace that melts steel scrap using the heat generated by a high power electric arc. During the melting process, elements are added to achieve the correct chemistry and oxygen is blown into the furnace to purify the steel.
