Abstract
The twin-roll continuous casting device comprises two counterrotating rolls (1, 2), having parallel axes, defining between them a casting space (5), and a shroud (4) placed above the casting space and including two longitudinal walls (41) which extend respectively along the surface of each roll. Each wall (41) includes two gas inlet pipes (45, 46) which include openings emerging towards the said surfaces, these pipes being mutually parallel and adjacent to the surface of the roll, and are separated by pressure-drop seals (50, 64) so that the flow of gas supplied by the pipe (45) lying upstream, in relation to the direction of rotation of the roll, is exclusively directed towards the outside of the shroud, the flow supplied by the pipe (46), located further downstream, being directed towards the casting space. Application especially to the twin-roll continuous casting of thin steel strip.
