Steel coil slitting machines specifically tailored for carbon and galvanneal strips provide precise slit coils for structural fabricators, roll formers, and component manufacturers. Shijiazhuang Faith Machinery Co.,Ltd offers slitting solutions optimized for medium and heavy gauge steel.
Equipment Layout
After coil loading onto the mandrel decoiler, strips pass through a hydraulic leveler to correct camber. The slitting station features robust knife shafts and bearings rated for up to 10 mm strip thickness. Following slitting, recoilers with disc‑type braking wind slit strips at controlled tension. Scrap edge trimming conveyors and shear choppers handle heavier edge waste efficiently.
Robust Construction
Knife shafts are machined from alloy steel and supported by high‑capacity bearings to withstand continuous loads. Guide rolls feature replaceable sleeves to accommodate mild steel, galvanized, or galvanneal strips without surface damage. The frame is welded and stress‑relieved for rigidity and alignment stability.
Process Control
Load‑cell‑based tension feedback upstream and downstream of the slitter maintains consistent strip tension across varying slit widths. Knife gap automatic adjustment ensures burr‑free edges. The central PLC synchronizes decoiler, leveler, slitter, and recoiler drives, while the HMI provides production data—line speed, slit widths, coil build diameter—at a glance.
Adaptable Configurations
Lines process strip widths up to 2,000 mm and thicknesses from 0.5 mm to 10 mm. Quick‑swap knife modules and optional dual‑frame configurations enable a mix of narrow and wide slit widths in the same run. Layout options include straight, L‑type, or U‑type lines to fit various plant footprints.
Support Services
Commissioning assistance ensures correct knife alignment, tension setup, and safety interlock functionality. Operator training covers blade change, troubleshooting, and preventive maintenance routines. A local spare parts inventory stocked with knives, bushings, and shear chopper blades supports rapid replacement.
