The invention relates to strip casting machines comprised of two parallel casting rollers (1,2) whose bearing journals (8,9) are supported on a stand (3). Cooled roll barrels of the casting rollers (1,2) and narrow lateral parts (5) delimit a casting gap (6). The aim of the invention is to obtain an optimal ratio between the width of the casting machine and the maximally castable strip width, to provide for a simple stand construction both for changing rollers as well as for exchanging narrow lateral parts, and to attain an improved protection against oxidation. To these ends, the invention provides that the cooled roll barrels are constructed as cylindrical casings (4). The casing (4) should be supported on a stationary axle, which is fixed on the stand (3), via the concentric support rings which project inside the casing (4) on both sides and which are connected to the same.

L'invention concerne des machines à couler des bandes comprenant deux rouleaux de coulée (1,2) parallèles dont les tourillons (8,9) sont en appui sur un montant (3). Des corps refroidis des rouleaux de coulée (1,2) et des parties des petits côtés (5) délimitent une fente de coulée (6). Afin de parvenir à un rapport optimal entre la largeur de la machine de coulée et la largeur de bande maximale pouvant être coulée, et afin d'obtenir un montant de structure simple, tant pour le remplacement de rouleaux que pour le remplacement de parties des petits côtés, ainsi qu'une meilleure protection contre l'oxydation, il est prévu de concevoir les corps refroidis des rouleaux sous forme d'enveloppes cylindriques (4). Des bagues d'appui concentriques faisant saillie de part et d'autre dans l'enveloppe (4) à laquelle elles sont reliées, permettent de soutenir ladite enveloppe (4) sur un pivot fixe fixé sur le montant (3).
