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.

Device for continuously casting liquid metal between two rolls

An apparatus for cooling an elongated product during its movement through the apparatus comprises an elongated tube having a cooling fluid inlet at one end and a cooling fluid outlet at the other end so that the cooling fluid will flow from the one to the other end through the tube. The product to be cooled passes through the tube either in the same or in a direction opposite to the direction of flow of cooling fluid through the tube. At least one centralizing element is provided in the tube spaced from the opposite ends of the latter and having a central passage coaxial with the tube and a diameter smaller than that of the tube for the passage of the product therethrough, and a plurality of channels uniformly distributed about the central passage to facilitate flow of cooling water from one to the other end of the tube. In this way a uniform cooling of the product is obtained even if the product is relatively long and heavy, such as steel bars, which due to their weight and their slow movement through the apparatus are liable to bend and come in contact with the tube in the absence of such centralizing elements.
