Installation for continuous casting between two cylinders (1, 2) on parallel axes defining between them and with two fixed side walls (3) a space for casting liquid metal, each side wall having at least one side part (6), placed against the plane frontal surface at the end of one of the cylinders, and consisting of a portion of disk whose external diameter is equal to that of the said adjacent cylinder, and one central part (12), in way of the casting space, made of insulating refractory material. The said portion of disk is made of a material whose properties of thermal conductivity and mechanical strength exceed those of the said refractory material, and is a portion of conical disk of which the face with the greater radius of curvature is located towards the cylinder, and the conical surface is in contact with the insulating material of the said central part. The invention applies to the continuous casting of thin parts in metal, including steel.

Installation de coulée continue entre deux cylindres 1,2 d'axes parallèles définissant entre eux et avec deux parois latérales 3 fixes un espace de coulée d'un métal liquide, chaque paroi latérale comportant au moins une partie latérale 6, placée contre la surface frontale plane d'extrémité d'un des cylindres, et constituée d'une portion de disque de diamètre extérieur égal à celui dudit cylindre adjacent, et une partie centrale 12, en regard dudit espace de coulée, en matériau réfractaire isolant. Ladite portion de disque est réalisée en un matériau présentant des caractéristiques de conductibilité thermique et de résistance mécanique supérieures à celles dudit matériau réfractaire, et est une portion de disque tronconique dont la face ayant le plus grand rayon de courbure est située vers le cylindre, et la surface tronconique est au contact du matériau isolant de ladite partie centrale. L'invention s'applique à la coulée continue de produits minces, métalliques, notamment en acier.
