摘要： A continuous casting installation of endless track type comprises a plurality of mould blocks (1) connected together in two endless tracks (2). The two tracks have runs which are disposed in opposed parallel relationship and each mould block (1) is of generally L-shaped cross section of which each limb (1a, 1b) cooperates and forms a seal with a limb of an associated mould block in the other track when the two said mould blocks are in the cooperating runs whereby the mould blocks in the said runs define a mould cavity (3). In use, the mould blocks in the said opposed runs are moved in the same direction and molten metal is poured into one end of the mould cavity (3) and a casting (5) is removed at the other end. A guide rail (10, 11) is situated within each track and the guide rails are offset in opposite directions from the centre line (1) of the mould cavity in the region upstream of the opposed runs. The guide rails (10, 11) cooperate with the mould blocks and guide them to move towards one another not only in the direction lying in the plane of the two continuous tracks but also in a direction perpendicular thereto whereby there is no risk of the corners of the limbs (1a, 1b) of the mould blocks (1) hitting one another.

摘要： A continuous casting installation comprises a plurality of mould blocks (1) arranged in two endless movable tracks. The two tracks have respective runs (7) which extend parallel to one another and together define a mould cavity along which the mould blocks (1) of the two tracks move in the same direction. At the downstream end of the two runs (7) the paths (9) of the mould blocks (1) of the two tracks extend in diverging straight lines (9a) from the points (P) at which the two tracks begin to diverge. A support device (6) for the casting (5) is positioned adjacent the two tracks in the gap between the downstream ends of the two tracks whereby the length of the casting (5) which is unsupported is minimised.

摘要： Apparatus for pouring molten metal into a continuous casting machine of moving mould type comprises a tundish car (10) which supports a tundish (9) and a tundish nozzle (11) which, in use, extends into the mould cavity of the casing machine. The tundish (9) includes an outlet portion (8) which is not connected to the tundish nozzle (11) but which defines a passage (13) communicating with the passage (13) within the tundish nozzle (11). Springs (16) connect the tundish car (10) and the tundish (9) and urge the downstream end of the outlet portion (8) into direct engagement with the upstream end of the tundish nozzle (11) or into indirect engagement with it via one or more intermediate members (19,20,21).
