Abstract: A method and apparatus for casting molten metal into ingots or bars. The molten metal is first disintegrated (fragmented) by a gas, via a lance jet, the gas including a powdered material of the same material as the molten metal and/or another material, to obtain a mixture of disintegrated molten metal and powder which is collected in a collector. The molten metal from a container pressurized by the gas is caused to flow out of an outlet in the container, and the gas containing the powder of pre-determined quantity and composition is caused to flow out from the mouth of a lance-shaped tube, the outlet end of which is surrounded by molten metal and is situated in or at the container outlet at which stage the molten metal is disintegrated and mixed with the gas contained powder and the resultant disintegrated molten metal mixed with powder grains is collected as an ingot or bar in the collector (mould).
