A method for making a thin cast strip with reduced meniscus marks includes assembling a pair of casting rolls laterally positioned to form a nip therebetween, preparing molten steel having a carbon content in the range of 0.01 to 0.3 % by weight, a manganese content between 0.1 and 0.8 % by weight, a silicon content between 0.05 and 0.5 % by weight, a calcium content between 0.0008 and 0.004 % by weight, an aluminum content between 2 and 500 ppm by weight, having a free oxygen content below about 50 ppm at 1600 °C, forming a casting pool of the molten steel supported on casting surfaces of the casting rolls above the nip, and counter-rotating the casting rolls cause thin strip to be casted downwardly from the nip.

L'invention concerne un procédé de fabrication d'une fine bande coulée présentant des marques de ménisque réduites. Ce procédé consiste à assembler une paire de rouleaux de coulée disposés latéralement de sorte à former entre eux un espace; à préparer de l'acier liquide présentant une teneur en carbone comprise entre 0,01 et 0,3 % en poids, une teneur en manganèse comprise entre 0,1 et 0,8 % en poids, une teneur en silicium comprise entre 0,05 et 0,5 % en poids, une teneur en calcium comprise entre 0,0008 et 0,004 % en poids, une teneur en aluminium comprise entre 2 et 500 ppm en poids, une teneur en oxygène libre inférieure à environ 50 ppm à 1600°C; à former un bassin de coulée d'acier liquide soutenu par les surfaces de coulée des rouleaux au-dessus de l'espace; et à placer les rouleaux de coulée en contre-rotation de manière à faire couler vers le bas une bande fine à partir de l'espace.
