摘要： Apparatus and method for filtering molten metal, in particular aluminium, including a container (1 ) with an outer shell or casing of metal and an inner thermally insulated interior cladding or wall construction made of heat resistant insulation and refractory material. A removable lid (2) provided on top of the container to keep the container sealed (air tight) during operation, the container (1) being provided with an inlet chamber (3) having an inlet opening (4) receiving metal from a metal supply launder (10) and an outlet chamber (5) with an outlet opening (6) in which a ceramic or refractory filter (7) is mounted. The inlet chamber (3) and outlet chamber (5) are provided side by side within the container (I) and being split by a partition wall (16) extending from the bottom of the container and upwardly to a preset level of the container interior height. The container (1) is connected in parallel with a metal supply launder (10) via transversal metal launder stubs (8, 9) respectively provided between the inlet (4) and outlet (6) openings of the container and the metal supply launder (10). On the other hand, the launder (10) is provided with a dam (I I) or valve device by the outlet of the container (1) and another other dam or valve device (12) between the two launder stubs (8 and 9), the inlet and outlet openings of the container being optionally further provided with closures or stoppers (13, 14) respectively enabling closing and opening of the inlet (4) and outlet (6) of the container respectively. The filtering of the metal is obtained by initially priming the ceramic filter by drawing the metal upwards through the filter by vacuum to a preset level and then maintaining the metal level in the container during the filtering operation.

摘要： An apparatus for pouring a molten metal comprises a crucible having a bottom wall member with an aperture formed therethrough and an integrally formed ceramic molten metal dispenser. The ceramic molten metal dispenser includes an upstanding first tube positioned within said crucible and having a first end located around the aperture and another second end that is closed. The first tube has at least one entrance for allowing the passage of molten metal from the crucible to the first tube, and has a double wall to define a molten metal receiving cavity. An upstanding second tube is located within the first tube and having one end coupled to the first end of the first tube and in fluid communication with the aperture and another end defining an inlet from the first tube. A passageway extends along the second tube for the passage of the molten metal from the entrance to the inlet.

摘要： A filter for molten metal is an open-pored porous material comprising particles of refractory material embedded in and bonded together by a carbon matrix bonding material. The filter can be made by forming a porous article from refractory particles, e.g. refractory oxide, carbide or graphite, and a carbon-rich binder, e.g. tar, pitch or an organic (preferably aromatic) polymer that degrades to form carbon on pyrolysis, and then firing the porous article to generate the carbon matrix in which the refractory particles are embedded. The porous article is preferably made by coating a reticulated polyurethane foam with binder and refractory particles, and firing at preferably no higher than 800 DEG C.

摘要： A method and an apparatus for enhanced metallurgical processing of molten metal includes an enclosable ladle chamber (23) for reducing the escape of heat during transport of the ladle from a manufacturing vessel such as a furnace (13) to an intermediate processing (15) or refining station or during processing or transport to a receptacle vessel such as a tundish (17). The method comprises introducing a refractory body into the ladle chamber (23), the body having an adjusted specific gravity having a reduced steel ballast to refractory material ratio that is less than required for a specific gravity required to buoyantly support the body in the molten metal. Preferably, the ratio provides a specific gravity greater than the specific gravity required to buoyantly support the body entirely in the slag layer. The method includes enclosing the ladle (22) for example, with a lid (90) and maintaining said refractory body in said ladle until substantially termination of the discharge of the molten metal from the vessel. Preferably, the method also includes intermediate refining such as introducing a balancing composition to the ladle before enclosing. The ratio of steel ballast and refractory material used to achieve the preferred specific gravity may also be adjusted in conjunction with other temperature-resistant or corrosion-resistant changes to the refractory body. For example, high temperature alumina may be used as a refractory material in a higher degree than in previously known bodies, a high temperature cement may be used to join the refractory material and ballast components, and a non-wetting agent made of carbonaceous or siliceous material may reduce deterioration of the body during the extended period of steel and slag contact in the ladle.

摘要： An improved vortex inhibitor (22) for separating slag from molten metal during the discharge of molten metal through a nozzle (14) includes a uniform castable refractory body (24) with a generally tapering shape, a hollow chamber (30) within the body and an elongated sacrificial member (32). The hollow chamber receives the sacrificial member or a mount for the sacrificial member. The refractory body (24) and the sacrificial member (32) combination in molten metal has a specific gravity less than the specific gravity of molten metal and is positioned narrow end downward when supported in molten metal. The hollow chamber (30) can fill with molten metal to form a core that aids in orienting the body in a narrow end downward position. The sacrificial member align the with the area in which the vortex forms and minimizes interference with the flow through the discharge nozzle (14). The body (24) preferably includes swirl obstructing surfaces.
