摘要： With respect to ceramic filters and filter systems for continuous metal melt filtration, to be able to counter high throughputs of steel melt and also the limitations of filter capacities during continuous casting, an alternative technological approach involves the use of novel, replaceable, and/or rotatable filter bodies at positions in the distributor channel. In some cases, the replaceable and/or rotatable filter bodies may be inserted into the distributor channel for 10 seconds to 30 minutes before being replaced. The filter bodies may be configured as an open-celled foam ceramic or a honeycomb body or a spaghetti filter and serve as a filter geometry of the replaceable and/or rotatable filter bodies in the distributor channel.

摘要： A device and method for transferring filtered molten metal to a die casting mold. The device and method include a casting filtration system that includes a funnel and a continuously replaceable filter placed fluidly between a molten metal source and a casting mold. Both the funnel and filter are automatically moved into cooperation with a molten metal receptacle such as a shot sleeve prior to each casting operation, and then automatically moved out of the way so that pressurization of the filtered molten metal may take place in the receptacle. In addition, the filter may be formed on a continuous strand such that indexed movement of the strand will advance the used portion of the filter out of the way to make room for a new unused filter portion that will be ready for a subsequent repeated casting operation.
摘要翻译： 一种用于将过滤的熔融金属转移到压铸模具的装置和方法。 该装置和方法包括铸造过滤系统，其包括漏斗和可流动地置于熔融金属源和铸模之间的可连续更换的过滤器。 在每个铸造操作之前，漏斗和过滤器都自动地与熔融金属容器（例如喷射套筒）配合，然后自动移出，使得过滤的熔融金属的加压可能发生在容器中。 此外，过滤器可以形成在连续的股线上，使得股线的分度运动将使过滤器的使用部分前进，以便为将用于随后的重复铸造操作准备好的新的未使用过滤器部分腾出空间 。

摘要： A method and apparatus for vacuum or air casting a molten superalloy, or other metal or alloy, containing an oxygen-reactive alloying element to form a cast part involves introducing the molten metallic material (melt) into a preheated mold having a melt reservoir, such as for example a mold pour cup, and gating for feeding the melt to one or more mold cavities. An induction coil disposed locally adjacent to the mold pour cup is energized in a manner to locally heat excess melt left in the melt reservoir to maintain it molten as the melt solidifies under vacuum or in air in the mold cavity to avoid shrinkage defects in the cast part.

摘要： A cast metal railroad car wheel includes a hub section, a tread section, and an uninterrupted annular web extending between and supporting the tread section on the hub section. The web includes a disk-shaped surface that is continuously concave and that does not include a reversely curved portion. A V-process casting process casts railroad wheels using a vacuum-process casting mold with opposing halves each partially filled with unbonded sand and sand-retaining-plastic film and a vacuum application port and that, when positioned together with the unbonded sand held to shape by vacuum and the film, define a cavity shaped to form a railroad car wheel. The V-process includes feeding molten metal into the cavity, cooling the molten metal, and releasing a vacuum to cause the sand to fall away from the railroad car wheel.
