摘要： A molten metal pump shaft coupling system for use in the coupling or connection of elongated shafts to other components and equipment, and for the disconnection thereof. A coupling with internal discontinuous threads may be coupled with an externally threaded shaft, with either continuous or discontinuous threads. Aspects of the invention include multiple external threads which may be pitched to accomplish a quicker and more efficient disconnect system. Furthermore, a shaft removal system is provided which provides two points of contact to assist in rotating a broken shaft end out of a coupling.

摘要： A molten metal or molten metal alloy is filtered to remove contaminants. Filters may include imaging agents, especially those useful for N-ray radiography, X-ray analysis, and neutron activation. Currently preferred imaging agents include gadolinia and tungsten. Currently preferred refractory materials include yttria, zirconia, tantalum, tungsten and rhenium. A homogeneous distribution of refractory and imaging materials may be accomplished by vacuum impregnation, chemical vapor deposition, physical vapor deposition, chemical vapor infiltration, fusing, cocalcining, alloying, and physical mixing. Filters substantially resistant to chemical and mechanical degradation may be used. For example, filters may be constructed with at least an outer layer of the filter comprising yttria. Filters may define a porosity and mesh size for efficient filtration and to exclude the maximum allowed size of defects for the particular application. Castings may be analyzed for inclusions by X-ray analysis, neutron activation, and N-ray radiography. Preferred methods for filtering melts include providing a filter including an imaging agent and filtering the melt into a mold to cast a metal article. Filtration may include heating the filter during filtration. The melt may include any molten metal or metal alloy, particularly aluminum, steel, alloys of titanium, chromium, nickel, cobalt and alloys thereof.

摘要： A method of adding gasses to, and removing gasses from a molten metal is disclosed. A molten metal is passed from a metal making furnace and cascaded through a gas or a flame. The flame is generated by a combustion burner and has an inner core of a first gas and an outer core of a second gas which jackets the first gas. As the metal is cascaded through the flame or gas, the first gas is passed into the molten metal. In the alternative, the cascade of molten metal may be passed through the first gas, or the first gas may be mixed with molten metal. The first gas may be used to sparge, react with, degassify, or otherwise dissolve within the molten metal. The device of the invention comprises a vessel for receiving the molten metal, a transfer trough extending from the furnace toward the vessel, and a combustion burner positioned with respect to the transfer trough and the vessel. The combustion burner is adapted to emit a flame or gas flow therefrom, and the transfer trough is adapted to pass the molten metal into the flame or gas flow, or to permit the flame or gas flow to pass through the molten metal as the metal enters the vessel. The device also includes a combustion burner constructed and arranged to cascade the molten metal as it is passed over a stair-step burner face provided as a part of the burner.

摘要： An apparatus for treating molten metal includes a treatment vessel for holding molten metal and a removable cover or hood for the vessel. Sealing means are provided between the cover and the vessel to provide a gas tight treatment zone. The sealing means include mating peripheral flanges on the vessel and cover, with the cover flange having three spaced annular sealing strips for contacting the vessel flange. These sealing strips include a first outer annular strip formed of an elastomeric material to give an air tight seal between the cover and vessel and a second middle annular strip formed of a deformable fibrous refractory material to provide a thermal barrier between the interior of the vessel and the outer annular strip. A third inner annular strip is a rigid metal strip upon which the cover is supported on the vessel with the cover flange at a fixed distance above the vessel flange and the outer sealing strip and middle sealing strip compressed therebetween to a controlled degree.
