摘要
The invention relates to steel production, especially to steel production facilities and methods of uninterrupted or at least cyclical steelmaking.The method includes in case of uninterrupted steelmaking at least the first three of the following steps and in case of cyclical steelmaking all five steps: charge materials are molten uninterruptedly or at least cyclically in an electric arc furnace (10); the charge materials like in particular shredded scrap-iron pieces (71) shredded in a shredding system (40) for shredding discarded iron and/or steel junk (70), direct reduced iron and/or hot briquette iron are uninterruptedly or at least continuously during a melting process cycle fed into the electric arc furnace (10) by means of conveyance (50, 51); a part of liquid steel is uninterruptedly or cyclically discharged from the steel bath of the electric arc furnace (10); from the thermic energy included in the hot process-exhaust of the electric arc furnace (10), electric energy is, by means of power generation (30, 31, 32), generated uninterruptedly or at least during a melting process cycle; a shredding system (40) assigned to the electric arc furnace (10) is powered uninterruptedly or at least during a melting process cycle by the electric energy generated from the process exhaust.
