High-Speed Slitting Line for CR Coil - Quality Supplier & Factory in China, Thickness 0.25-20 mm, Width 200-3000 mm
Product Introduction
The slitting machine is a key piece of equipment in industry for cutting wide metal or non-metallic coil materials into several narrow strips of the required width along the length direction. Its core working principle is to continuously roll-cut the material through the rotation of the upper and lower circular disc knife shafts.
The following is a comprehensive introduction to the core features of the slitting and shearing machine:
⚙️
Core Structure & Unit Composition
The core structure mainly consists of upper and lower knife shafts, fixed/movable frames, and a synchronous lifting mechanism. The knife shafts and frames undergo precise processing (such as turning, high-frequency treatment, grinding, and chrome plating, etc.) to ensure the rigidity and accuracy of the equipment.
🏭
Applicable to coils of various specifications — used for slitting coils into required widths through uncoiling, pre-leveling, cropping, slitting, and recoiling. Features proper layout, easy operation, high automation, and high production efficiency.
🔩
Adaptable to cold-rolled & hot-rolled coils, silicon steel coils, stainless coils, colored coils, aluminum coils, and all sorts of plated and coated coils — widely used in automobiles, containers, household appliances, food packing, construction materials, and more.

Frequently Asked Questions (FAQ)
❓
What types of materials can the coil slitting line process?
The coil slitting line is designed to handle a wide range of materials, including cold-rolled and hot-rolled coils, silicon steel coils, stainless steel coils, colored coils, aluminum coils, and various plated or coated coils. It is suitable for industries such as automotive, container manufacturing, household appliances, food packaging, and construction materials.
❓
What is the maximum coil thickness and width this slitting machine can handle?
Depending on the model, the slitting machine can handle coil thicknesses ranging from 0.2 mm to 6 mm, and coil widths from 400 mm up to 1,600 mm. The model 6×1500, for example, supports thicknesses of 1–6 mm and widths up to 1,500 mm with a maximum coil weight of 15 tons.
❓
What is the maximum line speed of the slitting production line?
The line speed varies by model. The 1.2×1250 and 3×1600 models can achieve speeds of 80–120 m/min and 90–120 m/min respectively, while the 2×1250 and 6×1500 models operate at 0–100 m/min and 0–60 m/min. The speed is adjustable to meet different production requirements.
❓
What are the main components included in the slitting production line?
The complete slitting line includes a loading cart, uncoiler, slitter, scrap winder, cropping shear, tension controller, and coil recoiler. Loop bridges, pinch rolls, and deviation correctors are installed between each unit to ensure smooth and precise material flow throughout the entire process.
❓
How does the slitting machine ensure cutting accuracy and equipment durability?
The knife shafts and frames are precision-engineered through multiple processing steps, including turning, high-frequency heat treatment, grinding, and chrome plating. These processes ensure exceptional rigidity, dimensional accuracy, and long service life of the cutting components, resulting in clean, burr-free slit edges.
❓
Is the coil slitting line suitable for fully automated production?
Yes. The coil slitting line is a fully integrated system combining mechanical, electrical, hydraulic, and pneumatic technologies. It features a high degree of automation with easy operation, proper layout, and high production efficiency, making it ideal for continuous, large-scale industrial production environments.
