slitting line

Uses and features

A slitting line, also called slitting machine, is suitable for unwinding the metal coil into a strip, slitting it into narrower strips of the needed width and recoiling them for sale or the next procedure.

Slitting line can be categorized into thin strip slitting line and thick strip slitting line for the thickness of the strip or copper strip slitting line, silicon steel, stainless steel, aluminum, carbon steel strip slitting line, etc for the material processed.

A slitting line is composed of

1.Loading coil car  2.Uncoiler  3.Straightener device   4.Pinch roll&leveler & hydraulic shearer   5.Loop pit   6.Side guide   7.Slitter   8.Transition platform & scrap winder   9.Loop pit   10.Tension station   11.Recoiler  12.Unloading coil car

Hereby take as an example a thin strip slitting line used for the uncoiling, slitting and recoiling of cold-rolled carbon steel, hot galvanized steel strip with thickness range of 0.3-3.0mm and width range of 800-1250mm.
