<P>PROBLEM TO BE SOLVED: To provide a pressurization-tapping type ladle for carrying molten metal, which is excellent in workability at introduction of pressurizing gas and/or at measurement of molten metal temperature. <P>SOLUTION: The ladle for carrying molten metal is provided with: a ladle body (not illustrated) storing molten metal; an upper cover 11 covering the upper end opening part of the ladle body; a working lid 13 covering, in an openable/closable manner, an opening part 12 formed in a part of the upper cover 11; a tapping part (not illustrated) extending from a lower end part of the ladle body to above the ladle body; and an annular part 14 arranged between the working lid 13 and the opening part 12 of the upper cover 11 and having an inside diameter substantially equal to that of the opening part 12 of the upper cover 11. The annular part 14 has a gas introduction hole 15 almost horizontally penetrating through the annular part 14. Thus, the ladle is composed so that gas for pressurizing the inside of the ladle body is introduced into the inside of the ladle body through the gas introduction hole 15. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
