Rolled sections with only a single symmetry plane tend to acquire deformations in this plane. These deformations stem from the dissimilar thermal evolutions of the different more or less massive parts of the section. The idea of the present study was to influence this differential thermal evolution by subjecting the more massive parts of the section to selective cooling. The theoretical study of the problem led to a remedy that could not be implemented for lack of sufficient cooling power during rolling. In the final solution the product's straightness is obtained by a selective cooling after rolling. The slight transverse deformation, which is a secondary effect of the technique, does not prevent its industrial application. The theoretical aspects of the process require further investigation.
