Description

Technical Field

[0001] The utility model relates to the technical field of novel section steel straightening, in particular to a Z-shaped steel straightening roll ring. Background Art

[0002] In fields such as building structures, bridge engineering, mechanical manufacturing and heavy-duty vehicles, the demand for high-strength, lightweight section steel is increasing. 350 Z-shaped steel, as a new type of hot-rolled asymmetric section steel, emerges as required. Its cross-sectional shape is unique, similar to the Chinese character "乙 (Yi)", with a relatively wide flange (commonly known as "leg width") on one side and a relatively narrow web (commonly known as "web thickness") on the other side. This asymmetric cross-section design endows it with significant advantages in mechanical properties: first, high flexural strength, the wide flange provides a larger section modulus, which can efficiently bear large bending moments; second, good stability, the large sectional moment of inertia makes it less prone to lateral buckling deformation under load; third, good economy, on the premise of achieving the same bearing capacity as ordinary symmetric section steels (such as I-beams), material saving can be realized, which conforms to the trend of lightweight design. During the cooling process after rolling, section steel will produce plastic deformation such as bending and warping due to uneven cooling rate of the section, and must be straightened by a straightening machine to meet the straightness standard.

[0003] Since the bending deformation of 350 Z-shaped steel after rolling and cooling is random, the contact and friction positions between the 350 Z-shaped steel and the straightening roll ring in the straightening machine also change accordingly. This uncertain contact relationship causes the wear on the working surface of the roll ring to present an unbalanced localized characteristic. In actual production, it often occurs that a specific area of the roll ring is preferentially worn to the limit due to bearing concentrated load, while the remaining parts of the roll ring still remain in good condition. However, the existing integrated roll ring structure cannot be locally repaired or replaced, forcing operators to scrap the entire roll ring, which not only causes waste of valuable component materials, but also significantly increases the spare part procurement cost and equipment maintenance frequency. For this reason, we propose a Z-shaped steel straightening roll ring. Summary of Utility Model
