0.2–2.5×1650mm slitting line

1. Equipment Overview
This is a 0.2–2.5×1650mm slitting line, manufactured by Jinan Yigao Machinery Co., Ltd. and put into operation in 2013. The equipment is still in active production as of today, meaning it is not idle or scrapped. It has proven production capability and is suitable for direct integration into existing production lines or for rapid deployment as a complete second-hand slitting solution.

2. Slitting Shaft System
The slitting shaft has a diameter of Ø180 mm, offering high rigidity and load capacity. This ensures blade stability during high-speed slitting, reduces vibration and deflection, and improves edge quality and blade service life. The shaft is driven by a 75 kW main motor, delivering sufficient cutting power for various thicknesses (0.2–2.5mm) and width combinations.

3. Recoiling System
The recoiler is equipped with an independent 90 kW drive motor, ensuring stable tension control even at high speeds, preventing coil loosening or misalignment. Its maximum coil weight capacity of 24 tons allows handling of large mother coils, reducing coil change frequency and improving continuous production efficiency, making it ideal for medium to large-volume metal processing operations.

4. Operating Speed
The line is designed for a maximum speed of 200 m/min, which is in the medium-to-high range for second-hand equipment of this type. This speed meets general productivity requirements while allowing precision processing for thinner materials, achieving both high quality and high efficiency.

5. Blade Configuration
The line comes with 150 blades included, offering great flexibility in blade arrangement. Users can quickly change blade combinations for different strip widths, material types, and thicknesses, reducing downtime and enhancing adaptability for diverse order sizes.

6. Equipment Condition and Reliability
Having been in continuous operation since 2013, the equipment demonstrates sound mechanical integrity, reliable electrical control systems, and well-maintained key components (e.g., shaft, recoiler, gearbox). For second-hand buyers, this “in-service” status is far more valuable than long-idle machinery, as its operating history is traceable and wear parts have been tested under real working conditions.

7. Application Scope
This slitting line is suitable for longitudinal slitting of cold-rolled coils, galvanized coils, prepainted coils, stainless steel coils, aluminum coils, and other metallic materials. It is widely used in home appliances, automotive parts, construction materials, tube manufacturing, hardware processing, and related industries. With thickness coverage from 0.2mm to 2.5mm and a maximum width of 1650mm, it meets most conventional metal strip processing requirements.

8. Added Value
As a used metallurgical total solution provider, Keepwin Industry Co., Limited offers not only the main unit but also optional auxiliary equipment such as pay-off reels, uncoilers, tension stands, coilers, unloading devices, hydraulic systems, and electrical control systems to form a complete slitting line. Additionally, Keepwin provides installation guidance, commissioning services, spare parts supply, and after-sales support, reducing the risk of secondary deployment for customers.

9. Conclusion
In summary, this 0.2–2.5×1650mm slitting line is a well-proven, high-performance, fully equipped, and broadly applicable second-hand metallurgical machine. For companies seeking stable production capacity with a moderate investment, it represents a cost-effective, reliable, and mature solution.
