摘要:
A casting flow running system (11) for supplying liquid metal to a mold cavity formed in a casting mold includes a plurality of pipe sections (13) that are connected to one another; at least one ingate pipe (13) for connecting the casting flow runner system (11) with an ingate of a casting model forming the mold cavity; and a frame (15) made of a heat-resistant material disposed on the ingate pipe (13). The frame has a net-like webbing (18) made of a fireproof material tensioned therein and is attached to the ingate pipe (13) such that the netlike webbing (18) at least partially spans a cross section of the ingate pipe (13) and is positioned in a region proximate to a surface of a casting piece formed by filling the mold cavity.
摘要:
The invention relates to systems for transferring molten metal from one structure to another. Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel can enter the transfer chamber. A powered device, which may be inside of the transfer chamber, moves molten metal upward and out of the transfer chamber and preferably into a structure outside of the vessel, such as another vessel or a launder.

Embodiments of the invention are directed to a rotor for a molten metal pump and a molten metal pump including the rotor. The rotor has a main body and a top comprised of a material that is at least twice as hard as the main body. The top, among other things, may form a first portion of each rotor blade wherein the first portion directs molten metal into a pump chamber or other structure in which the rotor is mounted.
摘要:
A molten metal pump comprising an elongated tube having a base end defining an inlet and a top end defining an outlet is provided. The elongated tube is constructed of a reinforced fiber material (RFM). A shaft is disposed within the tube with an impeller secured to the shaft and disposed proximate the base end.
