(4.0- 16.0)mm×2200mm Slitting Line

This thick plate slitting line, also called a metal coil slitter, is used to slit thick steel master coil into smaller baby coils. The thick coil slitting line is composed of a coil-loading car, double mandrel big-load uncoiler, portal style coil-head guide, press and shovel equipment, double roller pinching feeder, five-roller leveler, end-cutter, roll table, central aligner, disc slitter, scrap winder, coil accumulator, pre-separator & tensioner, portal style coils-separator and presser, recoiler, coil unloading car, hydraulic control system, and electric control system.

Different model capacities:

Strip thickness: (3~12) mm, (4-16) mm, (5~20) mm; Strip width: 500-1800mm, 800~2000mm or 1000~2200mm.

Advantages & Characteristics
  • Strength and solidity is extremely important for thick sheet slitting machines. We take the metal coil slitter’s structural design and material usage into consideration during the design stage. For example, a portal style coil-head guide and press, a dual body scrap reeler, a five roller tensioner for recoiling, and a portal style coil pressing and separating bracket are all parts installed on the machine to ensure a high performance operation.
  • The double cone-mandrel decoiler is capable of not only bearing coils as large as 35 to 40T, but also makes it easy to load those coilers into a decoiler.
  • The coil-loading car has a support platform with two rotatable rollers at the edges. One roller solidly supports the large coil, while the other is loading a coil onto the double cone decoiler. Double rollers on the coil car platform rotate synchronously with the decoiling mandrel.
  • The strength of all rollers and shafts increase with the steel strip thickness.
  • Dual-body scrap winders are driven by two torque motors and two speed reducers.
  • The recoiling tensioner of the metal coil slitter uses a solid five-roller tensioning structure, thus providing a stable and even tension for recoiling.
  • The coils pusher is installed on the recoiler in order to push coils out while discharging slit coils.
  • AC motors and speed reducers drive the pinch-feeder & five-roller leveler and five-roller tensioner, while DC motors & speed reducers drive the slitter and recoiler.
  • The coil slitting machine's electric control is a Eurotherm 590 speed controller PLC control.
