HR/CR/Gl Slitting Line
The HR/CR/Gl slitting line’s function is to slit a wide coil to stated width strips coil along with the length direction which can be used for milling, welding pipe, cold bend forming, stamping as billet. At same time, changing different material blade can slit various metal coils. The slitting line is controlled by PLC programming, with the touch screen as the human-machine interface, automatic and manual interchangeable settings, with automatic start button, automatic stop button. After the manual threading of the steel coil slitting line is completed, the rest of the time the whole line can be in an automatic working state!
Flow Chart Of The Slitting Line
This HR/CR/Gl slitting line is composed of main components such as uncoiling, pinch primary straightening, slitting, tensioning, and winding. When the slitting machine is working, after the steel coil is installed on the uncoiler, the steel plate is pressed into the pinch and sent to the primary leveling machine. For the material distribution tension station, the strip steel coil is finally coiled by the winder, and then packed and transported out of the production line by the unloading trolley.

Main Machines Of The Slitting Line
This HR/CR/Gl slitting line is used to divide the different specifications of the coil along the length direction according to the need of different widths of the strip and wind up, the product can be used for rolling, welding pipe, cold forming, stamping and other materials.
It can process all kinds of hot rolled coil plate, silicon steel plate, stainless steel plate, color plate, aluminumplate and so on, At the same time, the replacement of different materials of the tool can be cut a variety of non-ferrous metal strip.
