Abstract
Un procédé permettant de préparer une surface de moule destinée à une machine de coulée continue comprend l'usinage de la surface du moule, qui permet d'obtenir une surface sensiblement lisse, et le rhéo-durcissement de sensiblement toute la surface usinée, qui impose à cette dernière un effort de compression. Dans le mode de réalisation préféré, ce rhéo-durcissement se fait par application d'un grenaillage de précontrainte contrôlé à la surface du moule. La surface peut ensuite être bufflée, ce qui donne un fini satiné, ou revêtue d'un matériau tel que nickel ou chrome. L'effort de compression résiduel produit par le rhéo-durcissement empêche les criques de se former ou de s'étendre à l'intérieur de la paroi de la face du moule, ce qui augmente la durée de vie de cette dernière et rend la machine plus sûre et plus efficiente.
