Can Cold Rolling Steel Coil Production Lines Meet the High Standards of the Automotive Industry for Ultra-Thin Sheets?

July 2, 2025

With increasing demands for lightweight design, safety, and energy efficiency in the automotive industry, ultra-thin, high-strength steel sheets are essential. Our 6-high reversible cold rolling production line is fully capable of meeting these strict standards with outstanding performance in precision, shape control, and automation.

 

 Key Advantages of Our Equipment:

  • 6-high roll configuration with intermediate roll shifting and work roll bending ensures excellent flatness, ideal for AHSS and stainless steel;

  • AGC automatic gauge control combined with X-ray thickness gauges enables ultra-precise thickness control (±5μm);

  • Reversible multi-pass rolling improves thickness uniformity and surface finish;

  • Rolls made from high-performance 9Cr2Mo, ensuring durability and minimal deformation;

  • Smart Siemens PLC control, easy operation with remote diagnostics and parameter adjustments;

  • High-speed capacity (up to 300 m/min) and 30-ton coil weight, perfect for large-volume production;

  • Customized engineering based on your material, dimensions, and layout requirements.

These features make our cold rolling line highly competitive in producing ultra-thin steel coils for automotive use.

 Typical Applications:

  • Car doors, roofs, and hoods

  • Chassis components

  • EV battery casings

  • High-precision cold-formed structural parts

In conclusion, our 6-high reversible cold rolling line not only meets but exceeds the automotive industry's high expectations for ultra-thin, high-strength steel processing.
