Abstract
The device comprises two parallel horizontal rolls (2a, 2b) delimiting therebetween an inserted volume for the liquid metal (1) to be cast, the ends of the volume being closed by plates (4) with a predetermined clearance between the latter and the surfaces of the rolls against which they are maintained. In order to maintain the clearance constant during successive castings, the plates (4) incorporate rolling members (7) bearing against the end surfaces of the rolls (2a, 2b) and projecting from surfaces of the plates (4) a distance equal to the desired clearance (e). The plates (4) are biased toward the rolls by springs (10) which bear against a frame (2). The rolling members (7) (rollers and/or balls) avoid any wear of the plates and this clearance is automatically maintained by the action of the springs (10) during the casting operations.
