Jiangsu Zhanyou Machinery Co., Ltd. is a specialized manufacturer of backup rolls and rolling rolls for the metal rolling industry. We focus on reliability, dimensional accuracy, and long service life. Our products serve hot rolling, cold rolling, and various mills. We combine advanced manufacturing with strict quality control. Our goal is to support efficient metal processing lines. We deliver consistent performance to mills worldwide. For a complete overview of our capabilities, visit our HOME page.

Backup rolls and work rolls are essential in hot rolling, cold rolling, plate, strip, and foil mills. They support work rolls and help control strip shape, thickness, and surface quality. These rolls are used in steel, aluminum, copper, and other non-ferrous metal processing lines. Proper roll selection directly affects product consistency and mill productivity. Our rolls are engineered to withstand high loads and harsh conditions. They ensure stable operation across diverse rolling applications.

In hot rolling mills, backup rolls must resist thermal fatigue and wear. In cold rolling, they provide rigid support for precise thickness control. For aluminum and copper processing, our rolls maintain excellent surface finish. Each application demands specific roll profiles and material properties. We customize every backup roll to match the mill's requirements. This tailored approach maximizes performance and minimizes downtime. Browse our full range on the PRODUCTS page.

We offer forged alloy steel and high-chrome iron options selected by application. These materials balance hardness, wear resistance, toughness, and fatigue strength. Forged alloy steel provides excellent core toughness for heavy loads. High-chrome iron delivers superior wear resistance for extended campaigns. Material inspection and traceability support consistent performance under high rolling loads. Every batch is tested to meet stringent quality standards.

Choosing the right material is critical for roll life and strip quality. Our metallurgists help customers select the optimal grade. We consider rolling speed, temperature, and coolant conditions. This ensures the roll performs reliably in demanding environments. Proper material selection reduces spalling and premature failure. It also improves surface finish and dimensional stability.

Our factory employs CNC machining, grinding, and finishing for tight tolerances and excellent surface finish. We control concentricity, cylindricity, and roll profile to meet mill requirements. Quality checks at key stages reduce vibration and improve strip flatness. This precision extends roll life and enhances product quality. Each roll is inspected against detailed drawings and specifications. We use advanced metrology to verify every critical dimension. Stay updated with our latest developments on the NEWS page.

Precision processing is not just about dimensions. It also involves surface integrity and hardness uniformity. Our grinding techniques minimize residual stresses and chatter marks. This leads to smoother operation and better strip surface. We continuously optimize our machining parameters for each material. The result is a roll that performs consistently from first use.

We provide in-house heat treatment including quenching, tempering, and stress relief. These processes adjust hardness and microstructure for specific rolling conditions. They help improve wear resistance, toughness, and dimensional stability. Our furnaces are equipped with precise temperature controls. Each cycle is monitored and documented for traceability. This ensures repeatable results for every order. For additional assistance, visit our Support page.

Heat treatment is tailored to the roll's application and material. For high-chrome iron rolls, we optimize carbide distribution. For forged steel rolls, we refine grain structure for fatigue resistance. Stress relief minimizes distortion during machining and service. Our team continuously refines heat treatment recipes. This dedication yields rolls that last longer and perform better.

We provide custom rolling rolls and backup rolls according to drawings and working conditions. Our support spans from material selection to final inspection. We are a reliable partner for metal rolling mills seeking consistent quality and service. With years of experience, we understand the challenges of rolling operations. Our engineers work closely with customers to solve problems. We deliver value through technical expertise and responsive communication.
