Abstract:
Methods and associated apparatus for semi-continuous casting of hollow ingots are described. In one embodiment a method for the semi-continuous casting of a metallic hollow ingot is provided. The method includes providing a mold comprising a mold center having an inner pipe and an outer pipe arranged to form an annular space for a cooling media and an outer mold, circulating a cooling media in the annular space, feeding a source material to the mold, heating the source material to produce a molten material, moving the mold center progressively downward relative to the outer mold, and solidifying the molten material to form a hollow ingot. Embodiments relating to an apparatus for semi-continuous casting of hollow ingots, and products resulting from the semi-continuous casting of hollow ingots are also described.
