Abstract
This invention relates to an improved mould for casting a standard Magnesium ingot. The mould is constructed so as to minimize the surface area of the molten Magnesium which is exposed to the surrounding air. This significantly reduces the reliance on costly or harmful gases typically used in the casting process. The vertical mould which is internally tapered, has an open top and a closure at the bottom thereof. The ingot is easily removed from the mould when said closure is opened. The mould is adapted for use as part of an automated process employing a cyclic conveyance system for efficiently producing Magnesium ingots from recycled scrap Magnesium.
Claims5
A vertical mold for casting a standard magnesium ingot comprising a vertically elongated and tapered chamber having a uniform cross section, an open top for receiving the molten metal and a closure at the bottom thereof operable to close and retain the molten metal within the chamber and to open to permit the removal of said ingot through said bottom of the mold, said open top having an area of less than 20 in2 and of more than 8 in2, wherein said closure comprises a wedge and wherein said bottom of the mold receives said wedge in sealing engagement with reference to the chamber and wherein said wedge is cooled by means of cooling channels.
