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:
-
Raw Material Width and Thickness Range
Ensure the line supports your material specs (e.g., 650–1450mm width, 2–3mm thickness). -
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). -
Rolling Speed (m/min)
Typical range is 150–300 m/min; higher speeds improve productivity but require more stable mechanical design. -
Maximum Coil Weight and Coil Dimensions
Confirm compatibility with your coil specs (e.g., max 30T, coil ID 610–760mm). -
Rolling Force (tons)
Determines the machine's ability to process high-strength materials like stainless steel or AHSS. -
Roll Configuration and Size
For example, 6-high mills with optimized work, intermediate, and backup roll dimensions for shape correction. -
Thickness Control System (AGC)
Is the system equipped with AGC and X-ray thickness gauges? These are vital for micron-level control. -
Automation and Control System
Is the system controlled via Siemens PLC or equivalent? Does it support remote monitoring, data storage, and fault alarms? -
Space and Power Requirements
Ensure your facility can accommodate the equipment footprint and power needs. -
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.
