The present invention provides an apparatus for strip casting of molten metal including a pair of casting rollers R1, R2, adapted to receive molten metal M along a horizontal axis, wherein a vertical distance separating the pair of casting rollers defines a molding zone; and an electromagnetic edge containment apparatus 15 positioned on each side of the molding zone having an induction coil wound about a portion of a magnetic member to generate magnetic lines of force upon application of a current, wherein the poles of the magnetic member are positioned distal from to aligned to the planar sidewall of the casting rollers and the current provides magnetic lines of force perpendicular to said horizontal axis that contain the molten metal in contact to the casting rollers without substantially increasing the temperature of the molten metal.

La présente invention concerne un appareil destiné à la coulée en bande de métal en fusion, comprenant une paire de rouleaux de coulée (R1 et R2) conçus pour recevoir le métal en fusion (M) le long d~un axe horizontal, une distance verticale séparant la paire de rouleaux de coulée définissant une zone de moulage ; ainsi qu~une appareil électromagnétique de confinement latéral (15) positionné de chaque côté de la zone de moulage, ayant une bobine d~induction enroulée autour d~une partie d~un élément magnétique afin de générer des lignes magnétiques de force lors de l~application d~un courant, les pôles de l~élément magnétiques étant positionnés à distance de la paroi latérale plane des rouleaux de coulée et étant alignés avec celle-ci, et le courant générant des lignes magnétiques de force perpendiculaires au dit axe horizontal, lesquelles maintiennent le métal en fusion en contact avec les rouleaux de coulée sans augmentation substantielle de la température du métal en fusion.
