From Heavy Steel Plates to Ultra-Thin Can Foil: The Cross-Boundary Application of Rolling Technology

From the steel structures of buildings to the precision enclosures within household appliances, and even metal casings as thin as a cicada's wing, rolling technology is ubiquitous. This article explores the innovative applications of rolling technology across diverse industrial sectors.
Rolling technology has evolved to encompass a wide array of specialised rolls and processes, catering to demands ranging from heavy industry to precision manufacturing.

🌉 Application Scenarios:
• Profile and Sheet Manufacturing: Roll forming is extensively employed in producing elongated components such as structural steel for buildings and automotive parts.
• Foil Rolling: For ultra-thin foils (e.g., aluminium foil, stainless steel foil), 20-roll mills prove indispensable. Their working rolls often employ high-speed steel, cemented carbide, or even ceramic rollers to meet stringent requirements for high surface quality, wear resistance, and fatigue resistance.
• Specialised Applications: For instance, spheroidal graphite cast iron rolls (featuring a hardened cast iron outer layer and a ductile iron core) effectively prevent edge spalling, extending service life by over tenfold in hot-rolled sheet levellers.
