Reference Configuration: 0.3–3.0 × 1650
The XIONGJIN 1650 Thin-Gauge Slitting Line is a reference coil-processing configuration for converting cold-rolled steel and stainless-steel coil into accurately slit strip coils. It is designed around a quoted thickness range of 0.3–3.0 mm and a maximum coil width of 1650 mm. The line combines controlled payoff, entry guidance, rotary disc slitting, edge-trim collection, strip separation, tensioning and recoiling in one coordinated process.
For service centers and coil processors, the objective is not simply to divide a wide coil. Consistent strip width, controlled edge condition, stable strip tension and orderly recoiling all determine whether the finished coils can move efficiently to downstream stamping, roll forming, tube making or other production steps. XIONGJIN configures the equipment sequence according to material, slit pattern, coil data, required output and plant conditions.
Raw Material
| Item | Reference specification |
|---|---|
| Material | Cold-rolled steel coil and stainless-steel coil |
| Coil thickness | 0.3–3.0 mm |
| Coil width | Up to 1650 mm |
| Reference tensile strength | σb ≤ 480 MPa |
| Maximum processed coil weight | 15 t |
| Coil inside diameter | Ø508 / Ø610 mm |
| Maximum coil outside diameter | ≤ Ø2000 mm |
The final material grade, surface condition, yield strength, protective-film requirement and coil build should be confirmed with XIONGJIN engineering before the line is specified. These factors affect slitter tooling, knife clearance, separator design, tension strategy and motor sizing.
Finished Product
| Item | Reference specification |
|---|---|
| Output | Precision-slit strip coils |
| Finished coil inside diameter | Ø508 mm |
| Maximum finished coil outside diameter | ≤ Ø2000 mm |
| Maximum finished coil weight | 15 t |
| Minimum slit width | 25 mm |
| Slit quantity | Up to 22 strips at 0.3 mm; 6 strips at 3.0 mm |
| Strip-width accuracy | ±0.05 mm |
| Reference burr target | ≤ 3% of strip thickness |
| Reference edge-trim width | 4–10 mm |
Actual width tolerance, burr requirement, strip count and recoiling quality depend on the input material, knives, spacer arrangement, strip width distribution, speed and operator setup. They should therefore be confirmed for each production program rather than treated as universal values.
Key Technical Parameters
| Item | Reference specification |
|---|---|
| Line speed | 0–120 m/min |
| Threading speed | 0–15 m/min |
| Slitter cutter shafts | 2 × Ø230 mm |
| Slitting blades | Ø350 × Ø230 mm |
| Slitter drive | 90 kW variable-speed motor |
| Approximate installed capacity | 270 kW |
| Reference electrical supply | 380 V / 60 Hz / three phase |
| Reference footprint | Approx. 27 m × 9 m |
The values above are taken from the supplied 0.3–3.0 × 1650 quotation as a reference configuration. Final speed, power supply, layout and component capacities require engineering confirmation against the customer’s coil data and local utilities.
Production Process
- Coil storage platform and hydraulic loading car
- Hydraulic decoiler with auxiliary support, peel table and straight-head function
- Pinch feeding and crop shear for head/tail preparation
- Front loop, side guiding and strip entry control
- Rotary disc slitting and edge-scrap winding
- Rear loop, strip separation and plate tension control
- Rear pinch feeding, rear shear and guide rolls
- Finished-coil recoiling, hydraulic support and unloading trolley
This sequence creates controlled material flow from the incoming master coil to finished slit coils. The front and rear loop sections help buffer the process, while the separator and tension table support orderly strip travel into the recoiler.
Major Equipment Sections
Hydraulic Coil Loading Car
The loading car transfers the master coil into the entry position for the decoiler. Its role is to support safe, repeatable coil handling and to align the coil for efficient loading into the line.
Hydraulic Decoiler and Pinch Roll
The hydraulic decoiler supports and pays off the coil. The entry pinch roll helps draw the strip forward in a controlled manner after the coil head has been prepared. Together with the peel table and straight-head arrangement, this section establishes stable entry conditions before slitting.
Side Guide and Rotary Disc Slitter
The side guide centers the strip before the slitter. The rotary disc slitter uses matched upper and lower knives with spacers to divide the parent coil into the required strip widths. Knife condition, clearance, overlap and setup accuracy have a direct effect on slit width, burr formation and edge quality.
Vertical Scrap Winder and Pressing Table
During slitting, edge trim is directed to the scrap winding system. The vertical scrap winder collects the trim in a controlled manner, while the pressing-table arrangement supports strip control through the downstream section. The exact scrap-handling arrangement is selected to suit trim width, material and production practice.
Strip Separator, Tension Table and Rear Shear
After the slit strips leave the slitter, the separator organizes them for recoiling. The tension table applies controlled resistance to help maintain coil build, while the rear shear and guide rolls support threading, strip control and orderly end-of-coil handling.
Recoiler and Unloading Section
The finished strips are rewound on the recoiler into individual slit coils. Recoiling performance depends on tension consistency, strip separation, coil support and the selected winding program. A hydraulic support and unloading trolley are included in the reference equipment sequence to support finished-coil removal.

Final pit dimensions, equipment spacing, electrical routing and operator access must be confirmed in the final engineering layout.
Configuration and Engineering Confirmation
This page describes a quoted reference configuration rather than a universal machine specification. XIONGJIN MACHINERY will confirm the final line arrangement after reviewing the coil material, thickness and width range, tensile strength, slit pattern, finished-coil requirements, target speed, available utilities and site layout. That review is essential for selecting suitable knife tooling, tension control, drives, automation and safety configuration.
