Description

Technical Field

[0001] This utility model relates to the field of steel straightening technology, specifically to a straightening device for hot-rolled steel. Background Technology

[0002] Section steel is a type of bar steel with a specific cross-sectional shape and size. It is one of the four major types of steel (plates, pipes, sections, and wires). H-beams, as a type of section steel, can be produced by hot rolling. However, after hot rolling, the section steel will shrink to a certain extent during the cooling process, causing deformation. Straight sections usually need to be straightened before leaving the factory to improve product quality.

[0003] Existing steel profile straightening devices drive the round steel to move through two rollers and straighten it laterally. However, after straightening, the helix of the round steel cannot be straightened. Therefore, after one straightening operation, the round steel needs to be rotated 90 degrees and then passed through the two rollers again. Thus, at least two straightening operations are required, resulting in low straightening efficiency for steel profiles. Utility Model Content
