Product Details

Dry rolls (with water jackets) are crucial auxiliary components specifically designed for cooling and supporting work rolls, primarily used in hot rolling processes (such as hot strip rolling and section rolling). Their core function is to achieve efficient cooling, prevent work roll overheating and deformation, and ensure the stability of the rolling process.

Dry rolls (with water jackets) are ingeniously designed, typically made from special wear-resistant and high-temperature resistant alloy materials to withstand extreme working conditions. During hot rolling, high-temperature steel billets release a large amount of heat energy when passing through the work rolls. If heat is not dissipated promptly, the work rolls will expand due to heat, affecting rolling accuracy and even causing damage. Through its internal, precisely designed cooling channels, the dry roll can quickly remove heat, effectively maintaining the work roll temperature within an ideal range. Furthermore, it reduces steam generated from direct contact between water and high-temperature work rolls, avoiding interference with the rolling process such as obstructed vision and reduced lubrication effects, thus further improving rolling efficiency and product quality. With the continuous advancement of materials science and manufacturing technology, the structure and materials of dry rolls are continuously optimized to meet the needs of more efficient and environmentally friendly steel production, becoming an indispensable part of modern hot rolling production lines.
