摘要： An apparatus and method for filtering molten metal, such as aluminum or an aluminum alloy includes at least one ceramic foam filter or any other type of filtration media such as porous tube or alumina balls disposed in a receptacle for the molten metal. A vibrator vibrates at least one of the filter, the receptacle or the metal and may be used to induce priming, filtering and/or drainage of the filter. The vibrator may be retrofitted to an existing filter system and may be adjustable in frequency and amplitude. The vibration may be continuous over a given period or produced in a single shock.

摘要： By blocking an angular extent of an annular skimming trap used for semi-solid injection, a notable reduction in lenticular defects and porosity are observed. The blocking can be performed by a ring having dimensions to completely occlude a prior art annular skimming trap throughout the angular extent, and providing complete and/or partial flow across the ring throughout the rest of the angular extent. Preferably an outlet to the ring trap includes a chamfered edge and/or a deflector for encouraging flow of the contaminated semi-solid material into the trap.

摘要： A method of and apparatus for continuous casting of thin cast strip including removing oxides from the casting surface of each casting roll by contacting the casting surface of each casting roll with a rotating brush between the nip and the casting area, determining the temperature in segments along the casting roll surfaces or across the cast strip adjacent the nip, and delivering gas adjacent the casting surface between the rotating cleaning brush and the casting area regulated in segments corresponding to the determined temperature in the segment to control the quality of the strip produced. The gas delivery adjacent the casting surface between the rotating brush and the casting area may be done in at least five segments along the casting roll, and the temperature determination step may be done in a continuum such as by a scanning pyrometer. The temperature determination of the cast strip may be done between 0.2 and 1 meter from the nip.

摘要： A ceramic investment mold is disposed in a casting chamber and communicates with a pour cup melt reservoir connected to the mold and having a reservoir volume for holding enough melt to fill the mold. The melt pour cup reservoir is communicated to the mold via an inverted loop feed gate so that the melt is fed from a lower region of the reservoir through the inverted loop feed gate to the mold upon gas pressurization of the reservoir. The loop feed gate is configured to have a loop region above the melt level in the reservoir so as to prevent melt flow from the reservoir to the more mold cavities in the absence of reservoir pressurization. While residing in the pour cup reservoir, oxides and other inclusion-forming particles in the melt can float to the upper surface of the melt, whereby the melt fed from the lower region of the reservoir to the mold via the inverted loop melt feed gate includes reduced amount of inclusion-forming particles. After the melt is introduced into the pour cup, a pressure cap can be positioned in sealing engagement with the pour cup to provide selective or local gas pressure on the melt in the pour cup reservoir to force the melt in the reservoir through the inverted loop feed gate into the mold cavities to fill same.
摘要翻译：陶瓷投资模具设置在铸造室中并与连接到模具的倾倒杯熔体储存器连通并且具有用于容纳足够的熔体以填充模具的储存器容积。熔体浇注杯储存器通过反向回路进料口与模具连通，使得熔体在储存器的气体加压时通过反向回送进料口从储存器的下部区域进料至模具。环路馈送门被配置为具有在储存器中的熔融水平以上的环区域，以便在没有储存器加压的情况下防止熔体从储存器流到更多的模腔。当存在于倾倒杯储存器中时，熔体中的氧化物和其它夹杂物形成颗粒可以浮在熔体的上表面上，由此通过反向环熔体进料口从储存器的下部区域向模具进料的熔体包括夹杂物形成颗粒数量减少。在将熔体引入浇注杯中之后，可以将压力盖定位成与浇注杯密封接合，以在倒杯容器中的熔体上提供选择性或局部气体压力，以迫使容器中的熔体通过倒置环进料门进入模腔以填充相同。
