Abstract
L'invention concerne un procédé de formation d'une bande mince de coulée présentant au moins une microstructure sélectionnée dans le groupe constitué par la ferrite polygonale, la ferrite aciculaire, la ferrite de Widmanstätten, la bainite et la martinsite, une rugosité de surface inférieure à 1,5 microns Ra et une épaisseur de calamine inférieure à environ 10 microns, lequel procédé consiste à appliquer un mélange d'eau et d'huile sur les cylindres de travail du laminoir à chaud, à faire passer la bande mince de coulée à une température inférieure à 1 100 °C à travers le laminoir à chaud dont les cylindres de travail sont enduits du mélange d'huile et d'eau et à protéger la bande mince de coulée des cylindres de coulée à travers le laminoir à chaud dans une atmosphère contenant moins de 5 % d'oxygène pour former la bande mince de coulée.The invention relates to a method for forming a thin casting strip having at least one microstructure selected from the group consisting of polygonal ferrite, acicular ferrite, Widmanstätten ferrite, bainite and martinsite, a lower surface roughness. at 1.5 microns Ra and a calamine thickness of less than about 10 microns, which method comprises applying a mixture of water and oil to the working rolls of the hot rolling mill, passing the thin strip of casting to a temperature below 1100 ° C through the hot rolling mill whose working rolls are coated with the oil and water mixture and protecting the thin casting strip of the casting rolls through the hot rolling mill in a atmosphere containing less than 5% oxygen to form the thin casting strip.
