摘要： 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.

摘要： In the top-and-bottom blown converter steel making process, a process is provided wherein the position of the bottom-blowing tuyeres is set such that the maximum X.sub.0 among the distances X between the respective tuyreres and the center of the converter bottom is up to 1.3 times the horizontal distance Y between the central vertical axis of the converter and the outermost boundary of a hot spot region developed on the molten iron surface by the top-blowing oxidizing gas from the lance. By setting the position of the bottom blowing tuyeres in this manner, the interference of the bottom-blowing gas with the top-blowing gas is promoted to enhance the agitation between the slag and the metal to reduce the concentration of iron value (T.Fe) in the slag, thereby improving the iron yield.
