Product Details

In steel production, rolls are the core components of rolling mills, directly participating in the plastic deformation of metal and playing a decisive role in the shaping, dimensional accuracy, surface quality, and production efficiency of steel products.

Rolls are usually made of high-hardness, high-wear-resistant alloy steel or cast iron to withstand the extreme working conditions in steel production, such as high temperatures, high pressures, and continuous mechanical stress. Depending on their function and application, rolls can be divided into various types, such as hot rolls, cold rolls, roughing rolls, and finishing rolls. Hot rolls operate in high-temperature environments and must have excellent heat resistance and hot fatigue resistance to ensure smooth rolling and shape stability of steel at high temperatures; cold rolls require higher dimensional accuracy and surface finish to meet the high-quality requirements of the final steel product.

In addition, the surface treatment technology of rolls is also crucial, such as shot peening, carburizing and quenching, and chromium plating. These technologies can further improve the wear resistance, corrosion resistance, and service life of rolls, thereby reducing replacement frequency, lowering production costs, and improving overall production efficiency. With the continuous progress of materials science and manufacturing technology, the research and development and application of new roll materials are constantly promoting technological innovation and green development in the steel industry.
