China Factory Custom Make Peng Xin Brand Alloy Ductile Cast Iron Roll Powder Coated OEM/ODM Accepted

In the competitive landscape of industrial manufacturing, the choice of core components like rolls directly impacts productivity and product quality. Peng Xin Brand, from a leading China factory, stands for excellence in custom-made Alloy Ductile Cast Iron Rolls. We offer comprehensive OEM/ODM services, integrating advanced material science with protective powder coated finishes to deliver rolls engineered for superior performance and extended service life in the most demanding applications.

Advanced Material: Alloy Ductile Cast Iron

Our rolls are manufactured from a proprietary Alloy Ductile Cast Iron, a material engineered to surpass the capabilities of standard grades. By adding specific alloying elements like Nickel, Chromium, and Molybdenum, we achieve a refined microstructure that delivers:

• Enhanced Strength and Hardness: Withstands extreme rolling pressures without deformation, maintaining precise profile and dimensional stability.

• Superior Wear Resistance: The alloyed matrix provides exceptional resistance to abrasion, significantly reducing roll surface degradation and extending intervals between re-grinding.

• Improved Thermal Fatigue Resistance: Withstands the cyclical heating and cooling inherent in hot and cold rolling processes, preventing the formation of fire cracks and spalling.

• Consistent Performance: The inherent properties of ductile iron, combined with alloying, ensure uniform hardness deep into the roll body, guaranteeing consistent product quality.

Precision-Oriented Production Process

The manufacturing of a Peng Xin roll is a meticulous process. It begins with a controlled melting and advanced casting technique to ensure a sound, dense internal structure with no defects. The cast roll then undergoes a precise heat-treatment cycle (annealing, normalizing, and tempering) to develop the optimal combination of hardness, strength, and toughness. Finally, the roll is machined to exacting tolerances using CNC lathes and grinders, ensuring perfect concentricity, surface finish, and dimensional accuracy.

Protective Powder Coating and Customization

To protect non-working surfaces from corrosion during storage or operation, we offer a durable powder coated finish. This tough, wear-resistant layer provides excellent protection against moisture and environmental contaminants. Our OEM/ODM model means we collaborate closely with clients to custom make rolls to their exact specifications—be it specific dimensions, hardness profiles, neck designs, or performance characteristics.

Critical Applications in Rolling Mills

Peng Xin Alloy Ductile Cast Iron Rolls are trusted in various rolling mill applications, including:

• Bar and Rod Mills

• Section Mills (for angles, channels, and beams)

• Strip and Plate Mills

• Cold Rolling Mills for non-ferrous metals
