Strip steel products with high strength, good toughness, easy to processing molding and good weldability and other excellent properties, which are widely used in ship, automobile, Bridges, buildings, machinery, pressure vessels and other manufacturing industries. Hot rolled strip steel slitting unit mainly complete the strip steel strip after processing into hot rolled products, including direct referrals from the main rolling line and after leveling process of strip cutting head and tail cutting, trimming, check and according to the production requirements of heavy volume, cutting into different article finished steel coil or vertical segmentation, and weighing, baling. Based on pangang hot rolling finishing production line 1450 slitting and rewinding unit automatic control system technical transformation of the actual engineering as the background, discusses the control system of hot rolled strip steel slitting unit composition, function; Introduces the influence level of strip steel slitting unit installed configuration structure of the profibus-dp fieldbus and GE - PLC automation system application system, as well as the coil slitting unit automatic height, width to neutralize an open-book, winding, the realization of the constant tension control.
