mill roll used in finishing

Runhao Machinery can customize various models and materials of rollers with a maximum diameter of 2000 millimeters and a maximum weight of 60 tons for customized section steel/bar/wire/plate/strip rolling mills. Rollers for the production of hot-rolled strip with a width below 1450 millimeters can also be customized.

Finishing rolls are crucial equipment in the hot rolling process, specifically designed for the final stages of metal processing, known as "finishing." Here is a detailed overview of these rolls:

Role and Function:

Finishing rolls play a pivotal role in the concluding stages of the hot rolling process. They are utilized for the final shaping of metal billets, ensuring precise dimensions, smooth surfaces, and excellent surface quality.

Types and Structure:

Similar to roughing rolls, these rolls consist of work rolls and backup rolls. However, compared to roughing rolls, their design is more sophisticated. Work rolls apply precise rolling force, while backup rolls provide support, ensuring optimal refinement in the last rolling stage.

Applicable Materials:

Finishing rolls are versatile and suitable for various high-quality metal materials, including premium-grade steel, aluminum, and more. The design and manufacturing process consider the unique characteristics of different materials to guarantee the high quality of the final product.

Materials and Manufacturing Process:

To ensure durability in high-temperature and finely controlled rolling environments, finishing rolls are typically crafted from special alloy steels and other wear-resistant materials. Rigorous heat treatment and surface treatments are applied to guarantee superior performance during the final rolling stage.

Surface Treatment:

The surfaces of finishing rolls undergo specialized treatments, such as chrome plating, to enhance hardness, reduce friction, and ensure the final product possesses the desired surface smoothness and texture.

Key Design Features:

The design of finishing rolls takes into account the stringent requirements of the final product. Their precision in rolling capability and superior surface quality make them an indispensable component in the hot rolling process.
