The casting roll includes a hub (2) and a shell (3) which are arranged coaxially, and two flanges (5, 6) for supporting and radially centering the shell on the hub. Each flange includes a frustoconical part (51, 61) which cooperates with a corresponding frustoconical surface (34, 35) of the bore in the shell, the frustoconical surface being located in a region (A) where the internal diameter variations of the shell due to the expansion deformations are substantially zero.

Casting roll for a plant for continuous casting onto one or between two

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

A strip is continuously cast between rolls that includes a pair of rolls driven in rotation, two side dams urged against the ends of the rolls, and a jack for pressing the side dams against the rolls. The thrust force on the side dams is measured and the friction force exerted on the side dams by the rolls as a result of the rolls rotating is measured. From these measurements of thrust and friction forces, a coefficient representative of friction conditions between each of the surfaces of contact between the side dams and rolls is deduced and casting parameters are adjusted in response to the contact state between the surfaces.
