Steel Coil Slitting Line For Cold Rolled CR Steel Sheet (0.2-3 X 1250)
Carbon steel sheets are most common metal sheet, most of carbon steel sheets are low carbon steel (mild steel), medium and high carbon steel sheets are high quality high tensile steel, hot rolled HR carbon steel coils are thicker range of steel sheets before cold rolling process,
Cold Rolled Steel coil is thin sheets after cold rolling, the thickness range usually below 2mm, the minimum thickness can be around 0.2mm, it requires high precision high speed slitting. We often see CR, GI and colored sheets slitting on the same slitting machine. We give various options of configuration slitting lines for customers to choose, which needs customer telling their plan of production, then we calculate the slitting speed, slitting precision and automation. Each slitting line is customized, thus most suitable for customer.
