Description

Technical Field

[0002] With the continuous development of industrial technology, the demand for special-shaped pipes is increasing in various fields. The manufacturing and processing of special-shaped pipes has a profound impact on many industries.

[0003] The cold rolling process, that is, the rolling process carried out below the recrystallization temperature of the metal or alloy, is a key step in improving material properties. Cold rolling equipment is the core machinery for transforming raw materials into finished products. Through cold rolling, the mechanical properties of steel coils such as elongation, tensile strength and yield strength are significantly improved.

[0004] The steel coil is pickled before cold rolling, and then fed into the cold rolling mill. The steel coil is continuously rolled by the rollers of the cold rolling mill, and then cold rolled for multiple times according to the shape and size requirements of the special-shaped tube. Each rolling will further deform the material and gradually approach the shape of the final product. During the cold rolling process, the steel coil passes through the cleaning roller to remove the pickling solution on the surface to prevent rust. However, the cleaning roller has limited dirt holding capacity, and the pickling material will gradually accumulate on its surface. During the cleaning process, the cleaning roller is in continuous contact with the surface of the steel strip for a long time, which will cause overheating and aggravate the wear of the cleaning roller.
