Abstract: The invention relates to a casting method for aluminium or aluminium alloys, in which molten aluminium is treated and fed to at least one casting station (33, 34), in which the molten metal is cast into semi-finished products or similar. A number of casting ladles (25) are used to treat and feed the molten aluminium to the respective casting station (33, 34). The ladles are filled with the molten metal and the latter is then transported to at least one additional stage (32), where it is treated. The molten metal is subsequently delivered in the ladles (25) to the casting station (33, 34), where the ladles (25) are emptied. The invention thus provides an efficient method that can be flexibly adapted to the time periods of the process, said periods altering according to the situation.

Abstract: Described herein are methods, systems, and articles that are useful for controlling a fluid blending system, such as a fluid utility system. The methods, systems, and articles of this invention allow for the control of both a quantity metric (e.g., pressure) of the blended fluid the fluid blending system as well as at least one quality metric of a blended fluid in a fluid blending system. For example, the methods, systems, and articles of this invention provide for the simultaneous control of both the pressure and quality of fuel gas within a fuel gas header system.
