Key Selection Points for Cold Rolling Mills by Bright Flat Steel Manufacturer

Flat steel is active in the building materials market, and the cold rolling mill for flat steel is a machine specifically designed for producing various specifications of flat steel and square steel. What requirements do bright flat steel manufacturers have for cold rolling mills? Next, we will provide a detailed introduction to the structural composition and compatible accessory combinations of cold rolling mills for flat steel.

The flat steel cold rolling mill and the twin-rib cold rolling mill are both cold rolling mills, classified as high-force cold rolling mills. The flat steel cold rolling mill converts different diameter billets into flat steel of specific sizes through several flat steel cold rolling mills. The cross-sectional deformation, from circular to rectangular or square, is significant, necessitating a production line of rolling mills, with each mill assigned a corresponding deformation amount.

 Bearings are an indispensable component in the assembly of any equipment with moving parts. The cold rolling mill for flat steel is equipped with various types of bearings, which differ in their load-bearing capacity. These include deep groove ball bearings, radial ball bearings, tapered roller bearings, and thrust ball bearings. During the rolling process, the flat steel rolling mill generates significant rolling force, primarily radial. Using deep groove ball bearings would result in an insufficient contact surface for the steel balls to withstand the high radial forces. Therefore, cylindrical roller bearings are the only viable option, as they can not only bear substantial radial forces but also certain axial forces. Mechanical calculations show that the flat steel cold rolling mill requires a significant amount of rolling force, and the bearing capacity of one or two cylindrical roller bearings would be less than the rolling force produced during operation. Consequently, it is necessary to choose specialized rolling mill bearings, also known as four-row cylindrical roller bearings in technical terminology.

The cold rolling mill bearings used for flat steel cold rolling, specifically the four-row roller bearings starting with the model "FC." These mill bearings are designed for the rolling process industry, including rolling of non-ferrous metals, ferrous metals, and non-metallic products. They are used at the roller diameter of the rolling system and on the drums. Typically, four-row cylindrical roller bearings are used to bear radial loads, while thrust roller or thrust ball bearings, as well as radial contact ball or roller bearings, are used to bear axial loads. Lubrication and cooling are now commonly achieved through oil-gas lubrication, oil mist lubrication, or grease.

The cold rolling mill for flat steel is equipped with special rolling bearings, which offer superior performance compared to other bearings, featuring a more rational structure and extended lifespan. The radial跳动 during the production process of the flat steel cold rolling mill is also minimized, resulting in higher-quality finished flat steel products.

To ensure the flat steel produced meets the standard requirements, careful consideration must be given to the selection of the cold rolling mill, as its structural model directly impacts the quality and service life of the flat steel.
