Slitting Line

The slitting line is used to cut wide strips into a certain width and then recoil them into several volumes needed width coil to meet the request of various procedures for ERW pipe and cold rolled section steel production. Suitable for processing cold rolled and hot rolled carbon steel, Mild steel, HGI，GI, CCI and etc.

The process begins with loading a large steel coil onto a uncoiler machine, which unwinds the coil at a controlled speed. Proper mounting and tension control ensure the steel feeds smoothly into the slitting line. Then the wide strip is leveled and stored into loop bridge, waiting to be slitted.

Under the aligning and pinching, the strip passes through a series of rotary slitting blades arranged to achieve the desired slit width. These circular knives cut cleanly across the steel without deforming the material, based on specifications provided by the customer.

The slit steel strips are then recoiled onto separate mandrels, facilitating easy storage and transport. Maintaining correct tension during recoiling is critical to prevent strip deformation or damage.

Our slitting line is manufactured in consideration of automation, high quality, energy saving, productivity and stability. We always take the maximizing automation efficiency and optimizing every process performance as the top priority.

Value Highlights

• Strict control in the processingof all components, fabricated parts with stress relieved by annealing, shot blasting and machining by modern precise CNC center.
• Coils perfectly wound thanks to the automatic tension control, avoiding strip deformation or damage
• Optimal producing performance by reducing downtime to a minimum by means of automatic tool exchange systems, change of separator shafts, fast threading, off-line strapping, etc.
• Heavy-duty bearing, and coupling with advanced oiling lubrication system, avoiding the wear of the bearing from wrong lubricating maintenance or not in time of manual operation.
• High automation for easy operation, efficiency and safety
