Title (EN) CASTING STEEL STRIP
(FR) COULÉE DE BANDE D'ACIER
Abstract: front page image
(EN)A casting roll for use in twin roll casting of steel strip. The roll has a casting surface (1a) textured by discrete protrusions (9) tapering upwardly and inwardly to peaks of uniform height (H) disposed in a regular triangular, quadrilateral or polygonal array in which each peak is spaced from an adjacent peak by a distance (S) in the range 70 µm to 500 µm. Adjacent protrusions (9) are separated by generally flat regions of the casting surface through a distance (P) of not less than one half of the base width of the protrusions. The protrusions taper toward the peaks at an included angle of not more than 120° and preferably not more than 90°. The peaks may be rounded or alternatively may be truncated so as to have flat tops.
(FR)La présente invention concerne cylindre de coulée destiné à la coulée à deux cylindres de la bande d'acier. Le cylindre présente une surface de coulée (1a) texturée de protubérances discrètes (9) s'effilant vers le haut vers l'intérieur en forme de pointes de hauteur uniforme (H) disposées en matrices régulières triangulaires, quadrilatérales ou polygonales dans toutes les pointes sont séparées d'une pointe adjacente d'une distance (S) allant de 70 µm à 500 µm. Les protubérances adjacentes (9) sont séparées généralement par des plats de la surface de coulée sur une distance (P) n'excédant pas la moitié de la largeur de base des protubérances. Les protubérances s'effilent vers les pointes selon un angle fermé n'excédant pas 120°, et de préférence n'excédant pas 90°. Les pointes peuvent être arrondies ou tronquées d'un plat.
