Abstract: Disclosed herein are gas control systems and associated methods of controlling gas in a mold in casting, such as aluminum casting. The system may have a first mass controller, a second mass controller, and a control device capable of switching the gas control system between a first operating state and a second operating state. The first mass controller and the second mass controller may have different flow rate ranges. In the first operating state, the gas control system may deactivate one of the first or second mass controllers, and in the second operating state, the gas control system may activate both first and second mass controllers.

Abstract: The invention relates to a method and a device for producing steel strips by means of belt casting, wherein a molten metal is output from a feed vessel onto a circulating casting belt of a horizontal belt casting system under protective gas by means of a gutter and a siphon-like outlet area designed as a casting nozzle. According to the method, at least one plasma jet, which renders the area of action inert and heats the area of action, influences the outlet-side area of the casting nozzle and the molten metal exiting therefrom at least during the casting process. For this purpose, at least one plasma torch, which produces a plasma jet and is directed at the outlet area of the casting nozzle in a direction opposite the casting direction, is provided according to the device.

Abstract: A very low pressure gas or blow forming process for shaping a bulk metallic glass (BMG) in its supercooled liquid state that avoids the fractional stick forces experienced by conventional shaping techniques by engineering the expansion of a pre- shape or parison of BMG material such that substantially all of the lateral strain required to form the final article is accomplished prior to the outer surface of the parison contacting the surface of the shaping apparatus is provided. The capability offered by the inventive shaping process to avoid the frictional forces exerted by the shaping apparatus surface allows for the formation of precision net-shape complex multi-scale parts and components using processing conditions inaccessible by conventional processes.

Abstract: The invention relates to a process and devices for casting components in metal alloys on the tilt casting principle in which a quantity of melt metered for casting is spread over a large gate cross section without turbulence from a melt container of the mould (30) into the mould (31) by rotating the casting device (1). To prevent the formation of oxide and weak structural points, the melt is taken from a metering furnace under a protective gas in a melt container connected to the mould and taken thence into the mould also under a protective gas. The melt hardens there under increased gas pressure on the feeder region of the casting, whereby its properties such as fine-grained, dense structure, high stability under load and accurately dimensioned surfaces are considerably improved.
