Roller Conveyor

Forged steel rolls offer high strength and excellent overall mechanical properties. They are well suited for applications with high rolling force and impact loads, such as breakdown mills, roughing stands, and backup rolls. Their main disadvantages are higher cost and stricter manufacturing requirements.

Cast steel rolls provide relatively high strength with more flexible manufacturing processes. With improvements in steelmaking and remelting technologies, their quality and reliability have steadily increased, making them viable alternatives to forged rolls in many applications.

Cast iron and ductile iron rolls feature high hardness and good wear resistance, producing excellent surface finish at relatively low cost. Ductile iron rolls, in particular, combine improved strength with good wear performance and are widely used in intermediate and finishing stands of small and medium rolling mills.

High-chromium cast iron and high-speed steel rolls offer outstanding wear resistance and improved high-temperature performance. They are increasingly applied in hot strip mills, section mills, and high-speed wire rod mills.

Tungsten carbide rolls, typically used in ring form, exhibit extremely high wear resistance and minimal elastic flattening. They are especially suitable for high-precision finishing stands and high-speed rolling applications.
