    摘要： A molten metal discharging device comprising:a stationary plate adapted to be mounted at a bottom portion of a container accomodating molten metal, the stationary plate having a molten metal passage bore for permitting the molten metal from the container to be discharged therethrough, anda slide plate slidable along a lower face of the stationary plate and adapted to open or close the passage bore by being slidably displaced relative to the stationary plate, in whicha circumferential wall of the passage bore in the stationary plate is made of dense refractory material and the circumferential wall made of the dense refractory material has a plurality of gas supply holes therein for permitting a gas to be supplied into the passage borehas less fear that the passage bore thereof may be blocked by the solidification of the molten metal and/or deposition of metal oxides and has an improved resistance against corrosion by the molten metal.

    摘要： A molten metal discharging device including a stationary plate of refractory material and adapted to be mounted at a bottom portion of a container for accommodating molten metal, the stationary plate having a molten metal passage bore for permitting the molten metal from the container to be discharged therethrough, and a slide plate of refractory material slidable along a lower face of the stationary plate and adapted to open or close the passage bore by being slidably displaced relative to the stationary plate, wherein the stationary plate includes a stationary plate main body having the passage bore therein, at least a major part of the main body being made of porous refractory material, the stationary plate main body having a chamber around a circumferential wall part of the passage bore and a gas introduction hole communicated with the chamber for introducing a gas from outside into the chamber, the circumferential wall part having gas supply hole elements for supplying the gas therethrough from the chamber to the passage bore enables to reduce the heat dissipation through the stationary plate and to thereby reduce the risk of clogging of the molten metal passage bore in the stationary plate due to the solidification of the molten metal or the like.
