摘要： When a body of startup material (70) has been interposed in the cavity (4) between the starter block (60) and a first cross-sectional plane (72) of the cavity transverse the axis (12) thereof, the starter block has commenced reciprocating along the axis, and the body of startup material has commenced reciprocating in tandem with it, through a series of second cross-sectional planes (74), layers (76) of molten metal are successively superimposed on the body of startup material adjacent the first cross-sectional plane of the cavity, and the layers promptly distend relatively periperally outwardly from the axis under the inherent splaying forces therein. The relatively peripheral outward distention of layers is confined with baffling means (26) which are peripherally outwardly flared about the axis of the cavity, so that the thermal contraction forces arising in each layer can counterbalance the splaying forces. An annular coolant chamber (118) is also provided about the cavity.

摘要： A mould for horizontal casting of molten metal comprising a mould body forming an open-ended mould cavity having an inlet end and an outlet end. An annular permeable wall member is mounted in the mould body adjacent the inlet end of the mould cavity with an inner face thereof forming an interior face of the mould. A refractory transition plate is mounted at the inlet end of the mould cavity, this transition plate providing a mould inlet opening having a cross-section less than that of the mould cavity. This provides an annular shoulder at the inlet end of the cavity. Means are provided for feeding molten aluminum through the inlet opening. Separate conduits are also provided for feeding a gas into the shoulder and via the permeable wall means for providing a layer of gas between the metal and the inner face of the mould. A gas that is more reactive with molten aluminum is fed into the shoulder and a less reactive gas is fed via the permeable wall. The reactions with the molten aluminum create a skin or shell on the aluminum which provides smooth passage through the mould and allows for more rapid secondary cooling of the emerging ingot.

摘要： Equipment for continuous, horizontal casting of metal, in particular aluminium. The equipment including an insulated reservoir or pool (2), which is designed to contain liquid metal, and a mould (3), which can be removed from the pool (2), with an insulating plate (19) with holes (25, 26) which communicate with the mould, the mould (3) including a preferably circular cavity (17) with a wall (12, 13) of permeable material for the supply of oil and at least one annular slit or nozzles (16) arranged along the circumference of the cavity for the direct supply of coolant. In addition to the oil gas, is supplied through the permeable material (12, 13) and annuli (20) are arranged between the permeable wall material and the mould housing (8) to distribute the gas/oil to the wall material. The annuli (20) is divided into sectors using plugs or similar restrictions (21) and are supplied with oil/gas via separate supply channels (10, 11) for each sector, thus making it possible to differentiate the supply of oil/gas around the circumference.
