High Speed Slitting Line

HIGH SPEED SLITTING LINEDescription  The line is fullgh speed and high precisioy automatic, especially for silicon steel (CRGO) coil longitudinal slitting with hin. The wide coil (1000/1250mm) shall be opened and cut into required width strips and then rewinded into rolled coil.  The line speed is up to 120m/min, the min. slits width can be 8mm/10mm/20mm, as per your requirements.  The main working flow is  Feeding trolley→ hydraulic single-load un-coiler→ feeding unit→ plate head cutter→ rectification unit→ main slitter → scrap winder→ loop bridge and buffer pit → pre-distribution & tensioning machine→ recoiler → unloading trolley→ hydraulic & electric controlMachine Features:  DC driving for slitting and recoiling  PLC automatic controlling, VF speed adjusting, touch screen operation  High quality alloy blade for precision working  International famous brand Electrical and Pneumatic elementsMachine main technical requirements Technical parameter Value Technical parameter Value Line speed0-120m/minSlitting quantityMax. 20 slitsCoil materialSilicon steel, etcSlitting widthMin. 8/10/20mmSlitting width toleranceUnder ±0.02mmCoil ODΦ800～1200mmEdge straightness accuracyUnder ±0.08mm/mCoil IDΦ508mmRe-coiling side shape toleranceUnder 0.5mmCoil weightMax. 5000kgProduction quantity after 1-time blade grinding (maintenance)≥800 tonsBurr5% of coil thicknessScrap width1.5～15mmSurface qualityNo folding, Angular, scratches, edge damage, oil, roller printing, creases and other defects
