Abstract:
Die vorliegende Anmeldung betrifft ein Schmelze-Überführungssystem enthaltend einen Behälter zum Aufnehmen einer Metallschmelze, einen Strömungskanal zum Fördern der Metallschmelze aus dem Behälter durch den Strömungskanal, einen Behälterdeckel zum luftdichten Verschließen eines Behälterinnenraums und eine Steuereinheit zum Steuern der Förderung der Metallschmelze aus dem Behälter durch den Strömungskanal, wobei die Steuereinheit eingerichtet und ausgebildet ist, die Metallschmelzeförderung bei einem Abfall des gemessenen Druckes anzuhalten. Ferner betrifft die vorliegende Erfindung ein zugehöriges Steuerverfahren.
Abstract:
Desenvolvido para evitar que vazamentos de metais no estado líquido adentrem pelos materiais isolantes e danifiquem as calhas refratárias, direcionando-os para fora do sistema é composto por um sistema de gavetas coletoras (1) providas de um canal de dreno (2) onde estão localizados dois sensores de monitoramento (3), tendo a gaveta coletora preferencialmente o formato retangular, com extensão pouco maior que a largura da calha refratária (4), sua largura dimensionada para cobrir as junções das calhas e a área de vedações, sua altura dimensionada para transpassar a camada de isolantes (6) e o suporte metálico (5), de maneira que o canal de dreno (2), onde estão posicionados os sensores de monitoramento fiquem dispostos no lado externo do suporte metálico, por meio de lacunas (8) que permitem acesso para manutenção interna das áreas afetadas pelo vazamento.
Abstract:
Computer-based methods and systems are provided for improved recognition and presentation of parts, such as machine parts, as well as methods and systems for modeling and predicting the cost of such parts.
Abstract:
Automated processes that dynamically control rate of delivery of molten metal to a mold during a casting process. Such automated processes can use dynamic metal level variation, control pin pulses and / or oscillation during the mold fill and transient portion of the cast. It has been found that such pulses keep metal flowing in a manner that addresses problems, particularly at the beginning of an ingot cast, associated with metal meniscus contracting and pulling away from the mold on the short faces and corners.
Abstract:
A cooling system (10) for molding fixtures, and particularly for foundry molds, comprising: - water treatment means (11) - compressed air generation means (12) - means (13) for pressurizing the treated water - a device (14) for mixing air with the treated water, and for the controlled ejection of atomized water under pressure toward a cooling circuit (16) of a molding fixture.
Abstract:
A process in direct chill casting wherein molten metal is introduced into a casting mold and cooled by impingement of a liquid coolant on solidifying metal in a casting pit including a movable platen and an occurrence of a bleed-out or run-out is detected the process including exhausting generated gas from the casting pit; and introducing an inert gas into the casting pit, the inert gas having a density less than a density of air; reducing any flow of the liquid coolant.
Abstract:
In accordance with one aspect of the present embodiment, disclosed is a system and method of processing sand mold castings including the steps of placing a mold on a translation surface of a first conveyor at a first position, the mold including a sand housing having compacted sand that encapsulates a casting. The mold is translated along the translation surface of the first conveyor from the first position towards a second position. Air is directed against the casting and temperature of the air and or casting is measured after the casting is being removed from the sand mold.
