ABSTRACT:
A pressure tapping type ladle for transferring molten-metal includes a ladle body for containing molten metal, a top cover covering a top opening of the ladle body, and an openable working cover covering an opening formed in a part of the top cover. The ladle also includes a molten-metal tapping portion extending from a lower portion of the ladle body to above the ladle body, wherein the working cover is equipped with a cover body covering the opening of the top cover, a gas inlet formed in a top panel of the cover body, and a heat-resistant layer provided inside the cover body. The heat-resistant layer is comprised of a gas-permeable fireproof material layer, and gas for pressurizing inside the ladle body is introduced from the gas inlet via the gas-permeable fireproof layer.
