摘要： Exemplary embodiments described herein relate to methods and systems for casting metal alloys into articles such as BMG articles. In one embodiment, processes involved for storing, pre-treating, alloying, melting, injecting, molding, etc. can be combined as desired and conducted in different chambers. During these processes, each chamber can be independently, separately controlled to have desired chamber environment, e.g., under vacuum, in an inert gas environment, or open to the surrounding environment. Due to the flexible, independent control of each chamber, the casting cycle time can be reduced and the production throughput can be increased. Contaminations of the molten materials and thus the final products are reduced or eliminated.

摘要： A single treatment compartment has a liquid metal inlet and outlet and a connection to a liquid metal-input trough. A treatment gas is injected into the liquid metal arranged in at least one sidewall of a ladles. The liquid metal inlet and outlet have an orifice positioned so as to be entirely underneath a level of the liquid metal during the treatment, in order to prevent entry of ambient air into the compartment during treatment. The treatment compartment includes an upstream part and a downstream part. The gas injection is accomplished in the upstream part. The compartment further has a filter located in the downstream part for degassing and filtering the liquid metal. Injection and filtration occur in close proximity to one another and within the same single treatment compartment.
