ABSTRACT:
Efficient coordination of processing (by desulphurizing) and moving hot metal from a direct smelter, producing hot metal on a continuous basis, to an electric arc furnace or furnaces, operating on a batch basis, is disclosed. The invention includes the use of hot metal storage devices, such as ladles, that are large enough to supply hot metal for a small number, preferably two or three, of electric arc furnace batch operations.
