Medium gauge Steel Coil sheet slitting line mainly for coil steel sheets of 3 to 8mm thickness, Coil sheet material can be hot rolled (HR, HRC, HRS), cold rolled (CR, CRC, CRS), Galvanized sheet (GI) or Stainless Steel sheet (SUS, STS, SS) below 6mm. Coil sheet width range vary from 1250mm, 1500mm, 1600mm, 1800mm, 2000mm, it depends on customer coming coil materials.
We give customized options, customer tells their coming raw materials, finished strips specification, production capacity, precision tolerances, etc, we will provide individual complete proposal of whole slitting line, including uncoiling slitting & recoiling process, delivery time, dispatch and after sale support. You will feel our professional guide and support.
Characters:
- Medium gauge Slitting line requires machines strong and precise, the sheet metal thickness two or three times of thin gauge sheet, this means machine structure will be proportionally strong, meanwhile the cutting precision is the same level as thin sheet (+/-0.10mm)
- the slitting speed usually is fast (50-120m/min) for different thickness sheet slitting, generally proportional to sheet gauge, the thinner speed higher, the thicker speed lower.
- Medium sheet tension station either the same as thin sheets, taking use of felt pads or rollers type, tension is adjustable.
- Recoiler separator either overarm type or portal frame type, parallel pressing down over recoil mandrel with coiling diameter increasing, the pressing pressure is adjustable.
- Uncoiler usually double mandrel type for heavy load metal coils.
- Scrap winder is heavy load, each side one winder, either drum type or center support type.

Q & A
1.Q: What thickness and width range does this line cover?
A: 0.5-5 mm, 0.6-6 mm or 1-8 mm depending on the configuration ordered, in coil widths of 1250, 1600, 1800 or 2000 mm. Coil inside diameter can be 508, 610 or 760 mm and coil weight up to 25-30 t.
2.Q: How many strips can it produce at 6 mm and 8 mm?
A: About 10 strips at 6 mm and 6 strips at 8 mm. Heavy gauge needs more power per knife, so the line is built with 300 kW, 370 kW or 540 kW installed power depending on the strip count required.
3.Q: What line speed is achievable on heavy gauge?
A: 120 m/min on lighter configurations, then 100, 80 or 60 m/min as gauge and strip count increase. Speed is set by the drive package, so the same line runs slower for 8 mm and faster for thinner coil.
4.Q: What materials can it slit?
A: Hot rolled, cold rolled, galvanized and stainless coil in the 2-6 mm range, with knife grade and slitter power chosen for the actual tensile strength. Material outside the standard range can be reviewed before ordering.
5.Q: What is the delivery time?
A: 150-180 days from drawing approval, as stated in the specification. Control is by Siemens PLC with touch screen, and installation supervision is quoted together with the line.
Build standards and working accuracy
Which components and brands go into a slitting line?
Structural parts are welded to a minimum throat of two thirds the thinner plate, shot-blasted before painting and finished with two top coats. Uncoiler, slitter and recoiler shafts are forged 42CrMo and supplied with a material certificate; gears are 20CrMnTi, case-hardened and ground. Bearings, hydraulic, pneumatic and electrical parts come from named suppliers — Yuken valves, AirTac cylinders, HIWIN linear guides, Mitsubishi or Siemens PLC, Proface HMI, OMRON sensors — and the final bill of components is fixed on the approved drawing for each line.
What slitting and recoiling accuracy can the line hold?
On a typical slitting line, slit width is held to ±0.05 mm on strip narrower than 100 mm and thinner than 1.5 mm, and to ±0.10 mm in other conditions. Camber stays within 1.0 mm over 2 m, burr within 3% of strip thickness for strip up to 1.0 mm and 4% between 1.0 and 2.0 mm, winding misalignment within ±1.0 mm and telescope within ±2.0 mm. Final tolerances are agreed on the drawing for the specific line.
How is the line installed and supported after delivery?
Engineers attend the customer's plant to supervise installation and train the operators on the line as built. Spare parts are supplied at any time, and remote technical support stays available for the life of the machine.
