Double Slitter Heads Coil to Coil Steel Slitting Recoiling Line For CR Carbon Steel Sheet

Coil to coil steel slitting recoiling line is a machine used for steel coil cutting and rewinding, which can automatically cut and rewind steel coils of different widths and thicknesses.

Its working principle is to unwind the steel coil on the large reel to the feed winch of the cutting machine, cut it by the cutting knife and split it into strips by the slitter, and finally obtain a small reel that meets the required width and length, and then rewind it. This machine integrates multiple functions such as unwinding, cutting, slitting, and rewinding, enabling efficient and automated operations, improving production efficiency and product quality.

Hot rolled HR carbon steel coils are thicker range of steel sheets made from hot rolling mill. Cold Rolled Steel coil is thinner sheets made from cold rolling, the thickness range usually below 2mm, the minimum around 0.2mm, slitting process is high precision high speed and thus productive. GI and colored sheets usually are CR steel sheet base and slit on the same slitting machine.

We give various options of configuration for customers to choose, customer tells their plan of production

• Incoming mother coil diemensions
• finished baby coils specification
• Annual production
• Slit precisions

then we calculate the slitting speed, slitting precision and automation. Each slitting line is customized, thus most suitable for customer.
