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