WD-1500×(1.2-5.0) Hydraulic Precision Slitting line

1. Main usage

It is used to slit the steel coil to the rated width. It could cut different kinds of metal coils with different blades and prepare the billet for next process ( such as rolling, welding pipe, cold bending and punching).

2. Technical process ( including the process drawing)

         Stuff preparing —stuff loading—stuff uncoiling—draw pinching-—front loop rack ( loop pit)—transition rolling platform—slitting line main machine—transition stuff guiding platform(edge wire pit)—edge wire coiler—back loop splint ( loop pit)—pre-sub/pressing materials tension damping device—pinching—coiler—unloading—production packing.
