A copper alloy material manufacturing equipment for manufacturing a copper alloy material by continuously casting molten copper. The equipment includes an element adding means for adding a metal element to the molten copper, a tundish for holding the molten copper containing the metal element, a pouring nozzle connected to the tundish to feed the molten copper from the tundish, and a trapping member arranged inside the tundish and including a same type of material as at least one of an oxide of the metal element, a nitride of the metal element, a carbide of the metal element and a sulfide of the metal element.

Steam exhaust ports are located around a perimeter of a direct chill casting pit, at various locations from below the top of the pit to the pit bottom to rapidly remove steam from the casting pit with addition of dry excess air. Gas introduction ports are also located around a perimeter of the casting pit and configured to introduce an inert gas into the casting pit interior.

Metal sheets (13) are produced from strand-shaped profiles (8) having a low thickness, made of magnesium or magnesium alloys by way of an extrusion system (1). The open or closed extruded profile (8) exiting the extrusion die (6-7) of an extrusion press (1) is shaped to obtain a flat metal sheet (13) and is then subjected to a defined shaping process by way of stretch-forming. The system for carrying out the method is essentially composed of an extrusion press (1) comprising a die plate generating the extruded profile and a shaping unit (5) following the die plate, wherein the shaping unit (5) is composed of a severing unit (2), a bending unit (3), and an unrolling unit (4).

A method includes: replacing a first casting system component by a second casting component; sensing a position of the second casting component relative to at least one of a reference position and a third casting component; determining an adjustment amount and/or direction of the second casting system component; and providing the adjustment amount and/or direction to an operator for adjustment of the second casting system component and/or commanding that the second casting system component be adjusted by the adjustment amount and/or direction.

An aluminum alloy contains at least 0.03 mass % and at most 1.5 mass % of Mg, at least 0.02 mass % and at most 2.0 mass % of Si, and a remainder composed of Al and an inevitable impurity, a mass ratio Mg/Si being not lower than 0.5 and not higher than 3.5. In a transverse section of the aluminum alloy wire, a rectangular surface-layer void measurement region having a short side of 30 μm long and a long side of 50 μm long is taken from a surface-layer region extending by up to 30 μm in a direction of depth from a surface of the aluminum alloy wire. A total cross-sectional area of voids present in the surface-layer void measurement region is not greater than 2 μm.sup.2.
