Detailed Content
Wide coils leave the mill in fixed widths. Downstream lines call for narrow strip in specific widths. The slitting step between them decides whether material moves into production or waits on the floor.
This page looks at what a steel coil uncoiling slitting line can cut, how strip count changes with thickness, what holds accuracy, and which stations keep output steady.
What This Line Can Process
This steel coil uncoiling slitting line handles material from 0.3mm to 3.5mm thick and 500mm to 1600mm wide. These ranges define the order sizes the line can take.
Downstream Applications
The slit strip serves as feedstock for downstream operations. Suitability depends on material and project conditions.
-
Automotive stamping: feedstock for body structural parts, exhaust pipes, and seat frames.
-
Welded tube production: feedstock for round, square, and rectangular tubes.
-
Construction profiles: feedstock for C purlins, Z purlins, roof panels, and wall panels.
-
Home appliances: feedstock for shells and internal structural parts.
How Strip Count Changes with Thickness
A steel coil uncoiling slitting line produces more strips from thinner material. For example, the line can produce these strip counts:
-
1mm material: 15 strips at a time
-
2mm material: 8 strips at a time
-
3.5mm material: 5 strips at a time
The exact number also depends on blade layout, incoming coil width, target strip width, and edge trim allowance. Orders with different thicknesses can run on the same machine.
How Slitting Accuracy Is Formed
This steel coil uncoiling slitting line carries a specified slitting width accuracy of ±0.05mm. Actual performance depends on material thickness, blade condition, and gap settings.
The blade specification is φ340 x φ220 x 15. These numbers represent blade outer diameter 340mm, inner diameter 220mm, and thickness 15mm. Blade material is H13K. Shaft material is 40Cr with a diameter of 220mm.
The slitter can switch between active shearing and pull shearing to meet accuracy requirements for different strip thicknesses. Blade condition still matters: as blades wear, burr may increase and slit width consistency may drop.
Which Stations Keep Output Steady
A steel coil uncoiling slitting line relies on several stations to keep strip moving. The line runs through entry coil car, decoiler, hydraulic press and pinch device, hydraulic cutter, looper 1, side guide device, slitter, scrap winder, looper 2, tension stand, recoiler, and exit coil car.
On this slitting line machine metal, the side guide adjusts from 500mm to 1600mm by motor driven screw. It holds the strip centered before the slitter. Looper 1 sits between uncoiling and slitting, and looper 2 sits between slitting and recoiling. The tension stand before the recoiler builds recoiling tension.
These stations work together. If the strip wanders, slit strips can come out wide on one side and narrow on the other. If tension is unstable, finished coils can come out loose.
Operation and Control
The line uses PLC variable frequency control for front to back speed adjustment. Centralized control brings line operation to the main control panel, which provides high and low speed adjustment and manual feeding.
This automatic metal steel coil slitter machine runs with a line speed range of 0 to 60 m/min. The operating crew is listed as 1 mechanical engineer and 2 common workers.
Site Related Configuration
This steel coil uncoiling slitting line includes a scrap winder after the slitter and before looper 2, rated at 4KW. It collects edge trim into a coil form.
For safety, the line has isolation protection mesh and an emergency stop button. The mesh separates moving parts from the operating area in the zones it covers. The emergency stop button cuts off power immediately in an abnormal situation.
