Ingot casting apparatus

In an ingot casting apparatus comprising open top ingot moulds hinged to an endless revolving hauling chain of an inclined conveyer and means for feeding molten metal into open tops of said ingot moulds, wherein the improvement comprises:

• ingot moulds arranged on an upper descending branch of said endless hauling chain of said inclined conveyer and movable in descending direction along said upper descending branch, each ingot mould consisting of a bottom having an upper moulding surface and an opposed lower external surface, two longitudinal sidewalls associated with said bottom and extending parallel to the direction of descent of said ingot moulds along the upper descending branch and a single transverse wall adjoining said sidewalls and bottom, said single transverse wall extending normal to the direction of movement of said ingot moulds along said upper descending branch and each transverse wall being shaped to define at least one opening within said transverse wall and extending through said transverse wall, said single transverse wall including an internal moulding surface cooperating with said adjoining side walls and the upper moulding surface of said bottom to define a portion of said open top ingot mould cavity, and an external surface adapted to cooperate with an adjacent ingot mould along said upper descending branch to define an open top ingot mound cavity:
• said ingot moulds being arranged along said upper descending branch to provide a series of open top ingot moulds and cooperating to define a series of ingot mould cavities which are in communication with one another by said openings within the transverse walls of adjacent ingot moulds;
• means for feeding metal to said open top ingot moulds being arranged along said upper descending branch and a cooled plate disposed above said series of open top ingot moulds and downwardly along the upper descending branch relative to said means for feeding metal to sequentially close the ingot moulds as they pass beneath the cooled plate.
