What Technical Parameters Should Customers Pay Attention to When Purchasing a Cold Rolling Production Line?

July 10, 2025

Cold rolling production lines are critical for processing high-precision metal sheets. Their technical specifications directly impact final product quality, production capacity, and operational efficiency. When purchasing, customers should focus on the following key parameters:

 

Key Technical Parameters:

  1. Raw Material Width and Thickness Range
    Ensure the line supports your material specs (e.g., 650–1450mm width, 2–3mm thickness).

  2. Finished Thickness Range
    Check whether the equipment can produce your target thickness—especially important for ultra-thin products (e.g., ≤0.18mm for automotive or electronics).

  3. Rolling Speed (m/min)
    Typical range is 150–300 m/min; higher speeds improve productivity but require more stable mechanical design.

  4. Maximum Coil Weight and Coil Dimensions
    Confirm compatibility with your coil specs (e.g., max 30T, coil ID 610–760mm).

  5. Rolling Force (tons)
    Determines the machine's ability to process high-strength materials like stainless steel or AHSS.

  6. Roll Configuration and Size
    For example, 6-high mills with optimized work, intermediate, and backup roll dimensions for shape correction.

  7. Thickness Control System (AGC)
    Is the system equipped with AGC and X-ray thickness gauges? These are vital for micron-level control.

  8. Automation and Control System
    Is the system controlled via Siemens PLC or equivalent? Does it support remote monitoring, data storage, and fault alarms?

  9. Space and Power Requirements
    Ensure your facility can accommodate the equipment footprint and power needs.

  10. Customization Flexibility
    Can the supplier tailor roll size, drive mode, and layout to your specific needs?

Conclusion:

The best cold rolling line isn’t always the biggest—it’s the one that fits your material, production goals, and plant capacity. A well-matched system ensures quality, efficiency, and long-term return on investment.
