A METHOD AND AN APPARATUS FOR MANUFACTURING A HOLLOW STEEL INGOT Abstract A method and an apparatus for manufacturing a hollow steel ingot are disclosed, which comprise coaxially arranging a cylindrical metallic core in a center of a mold and pouring molten steel into an annular casting space defined between the core and the mold to cool and solidify it. In this case, the core is constructed with a concentric double tube consisting of inner tube and outer tube and receives in its central portion a cooling gas tank provided at the outer peripheral surface with plural outlets opening toward the inner peripheral surface of the inner tube. An inert gas is flowed through an annular gap defined between the inner tube and the outer tube, while a cooling gas is blown toward the inner peripheral surface of the inner tube.
