Rolling mill rolls are the core components in metal forming. Choosing the right material roll directly impacts production efficiency, product quality, and cost control. At CYKC GROUP, we offer a full range of rolling mill rolls tailored to meet diverse rolling conditions and customer needs. Here’s a guide to the main material types and their advantages.
1. Cast Iron Rolls
➤ Grey Cast Iron Rolls
Economical and stable, grey iron rolls are made via sand casting and contain free graphite for self-lubrication. They resist thermal cracks and are ideal for light-duty roughing and structural rolling.
➤ Alloy Cast Iron Rolls
With added Ni, Cr, or Mo, these rolls deliver better wear resistance and strength. Suitable for medium to finishing stands, they offer enhanced hardness (38–50 HSD) with improved toughness and surface quality.
➤ Chilled Cast Iron Rolls (Clear or Indefinite)
Produced by suppressing graphite formation through rapid cooling, these rolls have hard wear-resistant surfaces (55–90 HSD) and tougher cores. Perfect for high-temperature and continuous operations.
➤ Composite Rolls / Duplex Rolls
Made by double pouring, combining a hard outer shell with a tough core. This structure offers high hardness (up to 95 HSD) and excellent resistance to cracking—ideal for high-load or precision rolling.
➤ S.G. Iron Rolls (Nodular Cast Iron)
These ductile iron rolls offer high toughness and wear resistance. With fine graphite spheres and pearlitic or bainitic matrices, they’re perfect for long rolling campaigns. Hardness can exceed 80 HSD.
2. Steel Rolls
➤ Cast Steel Rolls
Steel rolls outperform iron rolls in strength and impact resistance. Alloy additions like Cr, Ni, and Mo improve thermal crack resistance and wear life. Widely used in hot strip mills and roughing stands.
➤ Forged Steel Rolls
High-toughness rolls forged from steel ingots. Depending on heat treatment, they can reach 90–100 HSD (fully hardened) and perform well in cold rolling applications with heavy reduction forces.
3. Tungsten Carbide Rolls
➤ Carbide Composite Rolls
Made of sintered tungsten carbide with cobalt binders, these ultra-hard rolls (up to 90+ HSD) significantly extend rolling campaigns. They’re ideal for high-speed wire, bar, or precision profile rolling.
We offer both monoblock and composite carbide rolls, with optimized binder content and grain structure for your exact needs.
