Abstract
A casting apparatus is described for casting metal ingots of rectangular shape comprising a mould assembly mounted on a casting table. The mould assembly has a pair of opposed, outwardly curved long walls and a pair of opposed short walls defining a rectangular mould cavity. Both the opposed short walls and the opposed long walls are moveable to change the size of the cast ingot with the long walls being independently moveable from the short walls. Operative means are provided for simultaneously moving the opposed long walls symmetrically about the centre-line of the mould cavity in both inward and outward directions, and a vertically moveable bottom block is provided which is adapted to move downwardly and support a forming ingot.
