INTEGRATED PLANT WITH VERY LOW ENVIRONMENTAL IMPACT FOR PRODUCING HOT-ROLLED AND COLD-ROLLED STEEL STRIP

摘要

An integrated plant with very low environmental impact for producing coils of hot-rolled and cold-rolled steel strip comprises a foundry section (SF) for producing liquid steel directly connected to a continuous casting and hot rolling section (CCHR) with final winding of the strip into coils, which section (CCHR) is in turn connected to a cold rolling section (PCR) that is in connection with a finishing section (CF), said plant further comprising a longitudinal slitting section (SL) suitable to receive coils from each of said three working sections (CCHR, PCR, CF), a vehicle shredding section (AS) suitable to produce metal scrap fit for use as raw material in the foundry section (SF), a vehicle shredding residue burning section (ASRB) suitable to generate current to supply the plant, and a foundry slag treating section suitable to recycle the slag and recover heat therefrom.
