<p>In a metal treating apparatus having a pot (14) for holding a bath (12) of molten metal, transfer means for moving the molten metal in the pot (14), including a molten metal-lifting passage having a molten metal inlet opening (20) disposed in the pot for receiving molten metal therein; the metal-lifting passage having a molten metal outlet opening (22) for discharging molten metal received in the inlet opening (20) to a location above the inlet opening (20); the metal-lifting passage having a gas-receiving opening (24, 26) below the molten metal outlet opening; gas passage means for connecting a source of the gas to the gas-receiving opening in the metal-lifting passage such that the gas passes along the metal-lifting passage to induce a flow of metal from the molten-metal inlet opening (20) towards the molten-metal outlet opening, the improvement comprising: the transfer means comprising a cast refractory block (16) having said molten metal-lifting passage and the gas passage means formed in a monolithic structure. <IMAGE></p> |
