Bainitic Nodular Cast Iron Rolls feature an acicular (Bainitic-Martensitic) matrix in their microstructure. This structure is achieved through the addition of Ni, Cr, and Mo alloys, followed by precise heat treatment. Manufactured using centrifugal or gravity casting methods, these rolls ensure consistent quality and durability.
Key Characteristics
-
High Strength: Greater load-bearing capacity than Pearlitic Nodular Cast Iron Rolls.
-
High Toughness: Excellent resistance to mechanical stress and cracking.
-
Outstanding Wear Resistance: Enhanced durability in high-friction environments.
Applications
These rolls are ideal for:
-
Finish stands in bar, rod, and small section mills.
-
Finish stands in narrow hot strip mills.
-
Pre-finish stands in wire mills.
