    Abstract: A pressure type automatic pouring furnace is formed with a molten metal outlet which has an opening end opening at a lower elevation than the general portion of the floor of a molten metal chamber. Preferably, the molten metal chamber communicates with a groove type induction heater section at a lower section thereof so that the molten metal in the chamber can be effectively heated. In addition, the bottom wall of the molten metal outlet is declined for a given angle, e.g. 3.degree. with respect to the horizontal plane so as to prevent the molten metal from accumulating within the outlet.

    Abstract: A process and a device for discharging free-flowing media, especially molten metal that is contained in a hermetically sealable vessel having an outlet (2) that has a level-recording unit (3). Pressure is built up in the vessel by supplying a pressurized gaseous medium introduced into the interior of the vessel, whereby the liquid metal is forced from the vessel. After attainment of a certain level of the free-flowing medium in the outlet (2) as detected by the level-recording unit (3), the gaseous medium for building up the dosing pressure is further introduced into the vessel (1) for a predetermined or predeterminable amount of time. Control of pressure inside the vessel (1) is effected by a control unit (4) that receives corresponding signals from a time-recording device (15).

    Abstract: Metal flow control for a continuous casting process is provided by providing a gas back pressure bubble to block the flow of molten metal above the casting nozzle. Pressurized gas is provided to a cap positioned upstream of the nozzle and including a depending skirt that cooperates with a dam. When the gas pressure offsets the head pressure of the molten metal, the flow of molten metal into the nozzle is blocked. By terminating the control pressure, the flow of metal over the dam may be reestablished. The cap including the skirt and the dam form a weir assembly defining a channel along one side or around the periphery of the nozzle. The cap may be supported and fed with gas pressure through a duct from the side, or along the center of the crucible.
