The main equipment of steel coil slitting line, including reeling machine, feeding trolley, uncoiler, CPC centering device, unwinding telescopic platform, cutting head shear, center alignment and tensioning system, slitting machine, cross arm automatic Knife changing turntable, scrap rolls, discharge pinch rolls, tension trolley, rewinder, steel coil laminator, discharge trolley and cross-arm discharge turntable.

　　In addition to the characteristics of the horizontal coil uncoiler, the steel coil slitting line uncoiler also has precise uncoiling tension control. It is in the centerline position of the slitting line during the tape threading process, and the unwinding speed is adjusted to maintain a stable unwinding tension. In addition, the lower unwinding can be carried out with the cooperation of the feeding trolley.

　　1. The steel coil slitting line is divided into thin plate slitting line (processing thickness 0.1-3.0mm) and thick plate slitting line according to the thickness of the steel coil slitting line.

　　2. According to the metal material of slitting, it can be divided into copper strip slitting line, stainless steel slitting line, cold plate slitting line, silicon steel slitting line and tinplate slitting line.

　　3. According to the degree of automation, steel coil slitting line can be divided into automatic slitting line and semi-automatic slitting line.
