Mechanical behaviour of the slab during continuous casting*
Comportement mécanique de la brame dans la zone de refroidissement secondaire d'une machine de coulée continue d'acier
The internal quality of cast slabs mainly depends on the intensity of the deformations imposed to the solidifying shell during its withdrawal along the supporting system of the caster. The main deformations are the bulging of the shell due to the ferrostatic pressure and the deformation imposed by the geometrical defects of the rolls, such as misalignment or eccentricity.
The present paper deals with a theoretical and experimental study of the mechanical behaviour of the shell of the cast slab during its solidification along the caster, carried out in close collaboration with Sollac Dunkerque Works.
This work has been successfully carried out thanks to the help and advice of a large number of people. We would specially like to thank our colleagues working at Irsid (MM. Kraemer, Hensgen, Loubet, Spiquel, Brolund), at Dunkirk Steelmaking shop (MM. Duhamel, Pouchelle), for their precious contribution to this study. This work has been partially sponsored by the European Community for Steel and Coal.
This paper has been selected as the 1991 winner af the Franck B. McKune Award at the 74th Steelmaking Conference of AIME (Washington, DC, April 16, 1991). We thank the Iron and Steel Society for his permission to publish it in La Revue de Métallurgie.
