Slitting line is a kind of longitudinal cutting or cr slitting machine which can slit the steel coils into narrow coils. It includes the decoiler, slitter and recoiler to do the complete production. As a professional coil slitting line manufacturers, DUWELL can provide you with high-quality products. Please check the details of our producs.
Q & A Of coil slitting machine line
What is a Steel Slitting Line?
A steel slitting line is an automatic coil processing production line
used to cut wide steel coils into multiple narrow strips with high precision.
The steel slitting line machine uncoils, slits, recoils, and separates steel strips
according to required widths. It is widely used in roll forming, stamping,
automotive, and construction industries.
What is the line speed?
Standard line speed:
• 80 – 150 meters per minute
• High-speed slitting line up to 200 m/min available
Production speed depends on material thickness and strip quantity.
What types of materials can be processed in a slitting line?
Our coil slitting line can process:
• Cold rolled steel (CR)
• Hot rolled steel (HR)
• Galvanized steel (GI)
• Stainless steel
• Aluminum coils
• Pre-painted steel (PPGI)
Material thickness range:
0.3mm – 6.0mm (customizable)
What is the difference between slitting line and cut to length line?
Slitting line uses rotary knives to make continuous longitudinal cuts, producing multiple narrow coils.
Cut to length line cuts metal sheets into smaller pieces (e.g., blanks or sheets) rather than coils.
Can a slitting line handle different thicknesses of steel coils?
Yes, slitting lines are adjustable to process various thicknesses. Each line can slit a thickness range in one line, such as 0.3~3.0mm, 1.0~4.0mm. etc.
What is the slitting accuracy of your slitting line?
Our precision steel slitting line ensures:
• Width tolerance: ±0.05mm
• Burr control: minimal burr edges
• Smooth recoiling
• Uniform strip tension
High precision ensures better performance for downstream roll forming machines.
What are the main components of a steel slitting production line?
A complete automatic steel slitting line includes:
• Hydraulic decoiler
• Coil loading car
• Leveling machine
• Slitting head with circular knives
• Scrap recoiler
• Tension stand
• Recoiler
• PLC control system
Fully automatic systems reduce labor costs and improve efficiency.
How many strips can your steel slitting line cut at one time?
The number of strips depends on:
• Coil width
• Strip width requirement
• Material thickness
Typical configuration:
• 5–30 strips per coil
Knife quantity can be customized based on customer requirements.
Is your steel slitting line fully automatic?
Yes. Our automatic coil slitting line features:
• PLC control system
• Touch screen interface
• Automatic tension control
• Speed synchronization
• Emergency protection system
The system ensures stable, continuous, and safe operation.
What is the delivery time of your steel slitting line?
Standard production time:
90 days after deposit
Customized heavy-duty slitting lines may require additional time.
We can also provide kinds of sheet metal coil slitter for sale, if you are interested, please contact us.
