摘要： The invention provides apparatus and methods for discharging molten metal from a vessel based upon increasing the amount of molten metal moved into the vessel per unit time by a molten metal mover, such as a pump. This causes the level for at least part of the vessel to increase and so discharge through a discharge location. More reliable, safer to operate discharge of molten metal is provided as result.

摘要： In order to feed molten metal to a casting mold with precision while preventing introduction of metal oxide into a cylinder casing, an entire valve box 19 is disposed below a liquid level of the molten metal C inside a molten metal furnace D. A discharge duct 23 is upwardly open at a lower end of a valve-element moving space 24. An inlet duct 22 is open to the valve-element moving space 24 at a position higher than the discharge duct 23. Around an opening of the discharge duct 23 to the valve-element moving space 24, there is formed a lower receiving seat 29 in the form of a ring. A valve element 21 includes a lower contact portion 31 which comes into annular contact with the lower receiving seat 29 in association with a lowering movement of the valve element 21. The molten metal C inside the molten metal furnace D is introduced into a cylinder casing 4 by moving the valve element 21 to an inlet position where the lower contact portion 31 comes into the annular contact with the lower receiving seat 29 thereby to block communication between the discharge duct 23 and an inlet/outlet duct 8.

摘要： The invention relates to a method for measuring the amount of liquid metal contained in a tiltable casting furnace. A reference curve is established for the amount of metal contained in the furnace and the tilt angle of the furnace. This reference curve is established by first calculating a theoretical curve based on the geometry of the furnace and then correcting the theoretical curve based on the volume of metal used between one tilt angle and a greater tilt angle. The amount of metal contained in the furnace is read from the reference curve after the curve has been corrected for any deviation between actual metal level and reference metal level.

摘要： By a method that may be used for transferring molten metal by using pressurized gas, molten metal in a metal furnace is automatically sucked into a molten metal chamber installed within the metal furnace through a fluid suction pipe by a balanced pressure inside the chamber. Then, when the molten metal sucked into the chamber is transferred to a specified position through a fluid feed pipe by applying a pressurized gas from an upper part of the chamber, the flow rate of the molten metal at the junction part between the fluid suction pipe and feed pipe or at the opposed part of an open end of the fluid suction pipe against that of the fluid feed pipe is accelerated, creating a higher flow rate at other parts of the fluid feed pipe. A molten metal transfer apparatus includes a molten metal chamber installed in a metal furnace and having a tightly closed upper part. The molten metal chamber is connected with an inlet/outlet pipe for pressurized gas and the lower part of the chamber is connected with a base part of a fluid feed pipe. In the vicinity of the base part of the fluid feed pipe, a fluid suction pipe is connected, and the other end is opened at the lower part of the metal furnace, and the cross-sectional area of the fluid feed pipe at the junction between the suction pipe and the feed pipe is contracted so as to be smaller than that at other parts of the feed pipe.

摘要： Apparatus for delivering molten metal such as lead to a receiver comprising a variable speed pump and a delivery pipe leading from the pump. The delivery pipe has an upwardly extending portion which leads to a discharge orifice from which molten metal may be discharged. A variable speed motor drives the pump. A controller causes the motor to drive the pump selectively at a first speed sufficient to raise molten metal and maintain it at a predetermined level in the upwardly extending portion of the delivery pump and at a second speed sufficient to force molten metal in the delivery pipe from the discharge orifice.

摘要： Apparatus for supplying melt from a melt-holding vessel to a casting machine comprises a ceramic melt pump casing or housing submersible in the melt. The casing includes a melt-pumping chamber with a melt inlet and melt outlet and a piston-receiving bore communicated to the chamber. A piston having a ceramic pumping portion is movable in the bore relative to the chamber in a suction stroke to draw the melt into the chamber through the melt inlet and in a pumping stroke to discharge the melt from the chamber through the melt outlet to, for example, a melt casting machine. A melt inlet valve having a ceramic valve portion submersible in the melt is movable relative to the melt inlet to open/close the melt inlet when the piston pumping portion is moved in the respective suction/pumping stroke. A melt outlet valve having a ceramic valve portion submersible in the melt is movable relative to the melt outlet to close/open the melt outlet when the piston pumping portion is moved in the respective suction/pumping stroke. The casing, piston pumping portion, and melt inlet and outlet valve portions are supported from the support member so as to be submerged in the melt of the melt-holding vessel. Actuators provided for the piston and melt inlet and outlet valves are mounted on the support member above the melt.
