ZJ-(4-16)×2200mm full automatic high precision hot rolled steel
coil slitting machine
Introduction:
This thick plate slitting line, also called metal coil slitter, is
able to slit thick steel master coil into small baby coils. The
thick coil slitting line is composed of: 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, hole accumulator, pre-separator& tensioner, Portal
style coils-separator and presser, recoiler, coil unloading car,
hydraulic control, and electric control.
Capacity of different models of thick sheet slitting lines (metal
coil slitter):
Strip thickness: (3~12) mm, (4-16)mm, (5~20) mm;
Strip width: 500-1800mm, 800~2000mm or 1000~2200mm.
2. Double cone-mandrel decoiler, not only to bear big coils such as
35T or 40T, but also convenient for loading coil onto the decoiler.
3. Coil-loading car has support platform with twp rotatable rollers
at edge edges, while loading coil onto double-cone decoiler, on one
hand, solidly support a big coil; on the other hand, double rollers
on coil car platform rotate synchronously with decoiling mandrel.
4. Strength of all rollers and shafts increase with steel strip
thickness.
5. Dual-body scrap winders are driven by two torque motors and two
speed reducers.
6. Recoiling tensioner of the metal coil slitter, or sheet slitting
line,adopts solid five-roller tensioning structure, providing
stable and even tension for recoiling.
7. Coils pusher is installed on recoiler, to push coils out whiling
discharging slit coils.
8. AC motors and speed reducers drive pinch-feeder & five-roller
leveler and five-roller tensioner, while DC motors & speed reducers
drive slitter and recoiler.
9. Coil slitting machine's electric control: Parker Eurotherm 590
speed controller + PLC control.
Working Process:
Coil-loading — Double-mandrel uncoiler — Coil-head-feeding, press &
shoveling — Double-roller pinch feeding, five-roller leveling —
