What are the differences between hot rolling and cold rolling in a steel rolling mill?

Steel rolling mills produce steel using two methods: hot rolling and cold rolling. The main differences between hot rolling and cold rolling are:
1. Cold-rolled steel allows for localized buckling of the cross-section, thus fully utilizing the load-bearing capacity after buckling; hot-rolled steel, however, does not allow for localized buckling.
2. The causes of residual stress in hot-rolled and cold-rolled steel are different, resulting in significant differences in their cross-sectional distribution.
The residual stress distribution on the cross-section of cold-formed thin-walled steel is bending-type, while the residual stress distribution on the cross-section of hot-rolled or welded steel is membrane-type.
