Precision Work Rolls & Backup Rolls for Cold Rolling Mills

Engineered for Exceptional Surface Quality and Extended Campaign Life

In a cold rolling mill, the roll is the final, critical contact point that defines the quality and value of your finished product. The surface finish, hardness, and durability of your work rolls and backup rolls directly impact sheet quality, operational efficiency, and your bottom line.

Yile Machinery is a specialist manufacturer of high-performance rolls for cold rolling applications. We combine advanced forged materials, precision heat treatment, and ultra-fine grinding to produce rolls that deliver a flawless surface finish and superior wear resistance, reducing your cost per ton and maximizing mill uptime.

Key Features & Benefits:

• Superior Material Integrity: We manufacture rolls from premium forged materials like high-chromium forged steel (e.g., Cr3, Cr5) and High-Speed Steel (HSS). The forging process ensures a homogenous, refined grain structure free of internal defects, providing maximum toughness and resistance to spalling.

• Advanced Heat Treatment for Optimal Performance: Our rolls undergo a multi-stage, differentially controlled heat treatment process. This creates a deep, super-hard working layer for exceptional wear resistance, while maintaining a softer, tougher core to absorb rolling stresses and prevent catastrophic failure.

• Ultra-Precision Grinding for Flawless Finish: The roll barrel is ground and polished to a mirror finish with extremely tight tolerances on surface roughness (Ra), concentricity, and cylindricity. This ensures a perfect, uniform surface is imparted onto your steel or aluminum sheet, pass after pass.

• Longer Campaign Life: The combination of superior materials and deep case hardness results in rolls that maintain their profile for longer. This extends the time between roll changes, increasing mill productivity and delivering a lower total cost of ownership.

The Right Roll for Your Mill

We manufacture a complete range of rolls for all types of cold rolling mills and metal types. Our expertise ensures you get the optimal roll for your specific application.

Roll Types Manufactured:

• Work Rolls: The primary rolls in direct contact with the metal strip. Available in HSS and high-chromium forged steels.

• Backup Rolls: Large-diameter rolls that support the work rolls and provide rigidity to the mill stand.

• Intermediate Rolls: Used in multi-high mills (e.g., Sendzimir mills) to transfer force to the work rolls.

Applications:

• Carbon & Stainless Steel Cold Rolling

• Aluminum Sheet & Foil Rolling

• Copper & Brass Strip Rolling
