How CRGO Slitting Quality Affects the Finished Core Joint
Tóm tắt kỹ thuật
CRGO slitting quality affects more than strip width. Burrs, edge condition and strip shape can carry through cut-to-length processing into the assembled core. This video traces the production sequence and explains why measured edge quality and suitable knife setup belong in the control plan.
Bản chép lời
The slit edge is already shaping the finished core before cut to length begins. Wrong strip width changes the limb profile and net steel section. Camber curves the strip in its own plane. At a joint, that can leave a gap on one side and excess overlap on the other. Edge waves stop sheets lying flat; forcing them flat can add stress. Long slit edges also need burr control. Match knife clearance and overlap to the grade and thickness. Measure width at the coil head, middle and tail. Measure camber over a defined span. Use actual burr measurements to trigger blade maintenance, and control tension through recoiling. Trace assembly errors back to the slit strip.
