Analytical study of contact pressure reduction during cold rolling of thick strips with single-zone backward-slip process

Key Points

• Average relative stress on contact surfaces was significantly reduced during single-zone cold rolling, enhancing durability.
• Transitioning from double-zone to single-zone cold rolling lowered wear rates of the rolling rolls and reduced cracking risks.
• Analytical studies indicate that reduced contact pressure leads to longer service life for rolling rolls during manufacturing.
• Findings suggest the single-zone backward-slip process may offer a more efficient method in the cold rolling industry.
