The device includes two rolls (10, 11) held by bearings (13, 14) on a frame (16) and, for each roll, devices (22) for measuring the position of the generatrix diametrically opposite the neck between the rolls, at three or more points lying respectively in a mid-plane (P.sub.3) perpendicular to the axes and in secondary planes such as (P1, P5) parallel to the mid-plane, and means (23) for measuring, in the said mid-plane, the position of a generatrix lying at 90.degree. to the neck. The method according to the invention uses these measurements to determine continuously the gap between the rolls, taking into account the in-service deformations of the rolls.

Shaping of thin metal products between two rolls

Installation for continuous casting between two rolls (1,2) having parallel axes and defining therebetween and with two fixed lateral walls (3) a casting space for a liquid metal, each lateral wall comprising at least one lateral part (6) placed against the planar end face of an adjacent one of the rolls and constituted by a portion of a disc having an outside diameter equal to that of the adjacent roll, and a part (12) which is central relative to and confronts the casting space and is composed of an insulating refractory material. The disc portion is made from a material having properties of thermal conductivity and mechanical resistance superior to those of the refractory material and is a frustoconical disc portion whose face having the larger radius of curvature is placed against the adjacent roll and the disc portion defines a frustoconical surface which is in contact with the insulating material of the central part. The invention is applicable to the continuous casting of thin metallic products, in particular of steel.
