Forged Steel Mill Rolls | Work Rolls & Backup Rolls
Product Description
Maximizing Performance and Campaign Life in Your Rolling Mill
In the demanding environment of a steel or metal rolling mill, the performance of your work rolls and backup rolls is paramount. Roll failure leads to unscheduled downtime, lost production, and significant safety risks. The quality of the roll directly impacts the quality of the final product and the overall efficiency of your operation.
Yile Machinery is a specialized manufacturer of high-performance forged steel rolls for hot and cold rolling mills. By utilizing advanced forging techniques and proprietary heat treatment processes, we produce rolls with superior strength, wear resistance, and toughness, ensuring maximum campaign life and a lower cost-per-ton rolled.
Key Features & Benefits:
Superior Metallurgical Purity via Forging: Unlike cast rolls, our rolls are forged from high-grade alloy steel ingots. The forging process refines the grain structure, eliminates internal defects like porosity, and provides exceptional resistance to fracture under the immense pressures of the rolling stand.
Advanced Differential Heat Treatment: We employ sophisticated induction hardening or gas-fired furnace treatments to create a deep, hardened working layer on the roll barrel while maintaining a softer, more ductile core and neck. This results in:
High Surface Hardness: For exceptional resistance to wear, spalling, and surface fatigue.
Tough, Resilient Core: To absorb shock loads and prevent catastrophic roll fracture.
High Torsional & Bending Strength: Our rolls are engineered to withstand the extreme torsional stresses from the drive system and the bending forces exerted by the backup rolls, ensuring operational reliability.
Custom Forged for Your Mill: We manufacture rolls to your exact specifications. We work from your drawings to produce work rolls, backup rolls, and intermediate rolls for any type of mill stand, including finishing mills, roughing stands, and section mills.
Manufactured from Premium Alloy Steels: We select the optimal steel grade for your application, including proven alloys like 42CrMo4, 50CrMo4, 70Cr3, and other Cr2-Cr5 series steels, to achieve the perfect balance of hardness, toughness, and wear resistance.
