High Performance Rolls for Long Service Life in Rolling Mills
Pearlitic Nodular Cast Iron Rolls are widely used in rolling mills across Pakistan due to their excellent balance of strength, wear resistance, and thermal stability. Manufactured with a nodular graphite structure and pearlitic matrix, these rolls provide superior durability, making them ideal for finishing stands, section mills, and bar mills.
At Unisons Steel Solutions, we supply Pearlitic Nodular Cast Iron Rolls in Pakistan that are engineered to deliver consistent performance, reduce roll consumption, and improve surface finish in steel production.
Technical Specifications of Pearlitic Nodular Cast Iron Rolls
Technical Data Table
| Property | Specification |
| Material Structure | Nodular graphite with pearlitic matrix |
| Hardness (Shore C) | 60 – 75 |
| Tensile Strength | 500 – 700 MPa |
| Typical Applications | Finishing stands, section mills, bar mills |
| Wear Resistance | High |
| Thermal Shock Resistance | Excellent |
| Surface Finish Quality | Superior to ordinary cast iron rolls |
- Material Composition: Made from high-grade nodular cast iron with a pearlitic matrix, providing a combination of toughness and hardness.
- Microstructure: The nodular graphite structure enhances ductility while maintaining high strength, reducing the likelihood of cracking under stress.
- Thermal Conductivity: Excellent thermal conductivity helps in heat dissipation, minimizing thermal stresses during operation.
Comparison: Pearlitic vs. Bainitic Nodular Cast Iron Rolls
| Property | Pearlitic Nodular Cast Iron Roll | Bainitic Nodular Cast Iron Roll |
| Matrix Structure | Pearlitic with nodular graphite | Bainitic with nodular graphite |
| Hardness (Shore C) | 60 – 75 | 70 – 85 |
| Tensile Strength | 500 – 700 MPa | 600 – 800 MPa |
| Wear Resistance | High | Very High |
| Thermal Shock Resistance | Excellent | Superior |
| Surface Finish | Smooth & consistent | Slightly rougher but very durable |
| Best Applications | Finishing stands, bar mills, section mills | Hot rolling mills, intermediate stands, heavy-duty rolling |
| Service Life | Long | Longer under heavy load conditions |
Key Takeaway:
-
PNCIR → Best for finishing applications where smooth surface finish is critical.
-
BNCIR → Ideal for heavy-duty, high-load rolling with superior wear resistance.
