The invention relates to a method for producing a strand from a monotectic alloy which is made of multiple constituents and in which drops of a primary phase are distributed in a uniform manner in a crystalline matrix in the solidified state. The uniform distribution can be achieved during the production process using the following method steps: a) melting the alloy constituents which consist of at least one matrix component and components that form the primary phase and heating the constituents to a temperature at which a single homogeneous phase exists; b) transporting the melt (2) in the form of strands in a transport direction which is inclined towards the horizontal at a transport speed; c) cooling the melt (2) while transporting the strand lower face perpendicularly to the transport direction in order to form a crystallization front when transporting in a cooling zone; d) setting the cooling intensity, the inclination of the transport direction, and the transport speed such that a horizontal crystallization front is formed and the Marangoni force produced by cooling and forming the primary phase in the form of drops is oriented anti-parallel to the gravitational force such that the drops of the primary phase in the matrix component move in the direction of the gravitational force; and e) drawing the alloy which has been solidified into the strand (9) out of the cooling zone.

Described herein are techniques for improving the grain structure of a metal product by applying ultrasonic energy to a continuously cast metal product at a position downstream from the casting region and allowing the ultrasonic energy to propagate through the metal product to the solidification region. At the solidification region, the ultrasonic energy can interact with the growing metal grains, such as to deagglomerate and disperse nucleating particles and to disrupt and fragment dendrites as they grow, which can promote additional nucleation and result in smaller grain sizes.

A method for the continuous casting of metal strands. The liquid metal is simultaneously cast via a moulds into metal strands. The moulds each have a narrow side and a broad side. The moulds have a uniform narrow side so that the metal strands have equal thicknesses after casting. At least one of the moulds used has a broad side whose length differs from the length of the broad side of the other simultaneously used moulds. For each mould used, a sprue stone is provided, which is arranged on a casting table and is provided for receiving the starter strands. The casting of the metal strands includes a mould filling phase with a fixed casting table in which a plurality of starter strands is cast into the associated sprue stones. The casting includes a continuous casting phase in which the casting table is lowered and metal strands are cast.

An enclosure having a sealing device, for a casting installation, having a first body and a second body that is removably joined to the first body along a bearing axis, the first and second bodies together delimiting an internal chamber. The sealing device comprises: at least one compression member, at least one seal having a lateral contact face extending substantially parallel to the bearing axis; the compression member and the seal being arranged with respect to one another such that the compression member is in contact with the lateral contact face of the seal and exerts a compression force thereon that is oriented orthogonally to the bearing axis.

A thermally stable component formed of a tempered aluminum alloy casting which reduced costs is provided. The aluminum alloy typically has an elongation of at least 8% after casting, which is preferred for self-piercing rivet processes. The aluminum alloy leaves a casting facility in the as-cast (F temper) condition. The cast aluminum alloy is then shipped to another entity, such as an OEM, and is subjected to an artificial aging process, such as on the OEM's existing paint line, rather than at the casting facility. The artificial aging process typically includes electrodeposition coating and curing. The components that can be formed by the reduced cost method include lightweight automotive vehicle components, including structural, body-in-white, suspension, or chassis components, such as front shock towers, front body hinge pillars, tunnels, and rear rails.

Described herein are 6xxx series aluminum alloys with unexpected properties and novel methods of producing such aluminum alloys. The aluminum alloys are highly formable and exhibit high strength. The alloys are produced by continuous casting and can be hot rolled to a final gauge and/or a final temper. The alloys can be used in automotive, transportation, industrial, and electronics applications, just to name a few.

A method of producing aluminum alloy material having a thermal bonding function in a single layer and including 2.00 mass % to 3.00 mass % Si, 0.01 mass % to 0.50 mass % Fe, and 0.80 mass % to 1.50 mass % Mn includes a casting process performing a twin roll type casting to form a plate having a thickness of 3 mm to 12 mm by rotating a roll having a diameter D (mm) at peripheral velocity v (mm/min) being satisfying a following formula of 0.057?v+0.0016?D?33.54.

Grain size of a deliverable metal product can be improved by pre-setting recrystallization-suppressing dispersoids during casting. The outer regions of a direct chill cast embryonic ingot can undergo reheating before casting is complete. Through unique wiper placement and/or other reheating techniques, the temperature of the ingot can be permitted to reheat (e.g., up to approximately 410 C. to approximately 420 C.), allowing dispersoids to form. Stirring and/or agitation of the molten sump can facilitate formation of a deeper sump and desirably fine grain size as-cast. The formation of dispersoids during and/or immediately after casting can pin the grain boundaries at the desirably fine grain size, encouraging the same grain sizes even after a later recrystallization and/or solutionizing step.

An aluminum plate manufacturing method capable of achieving an enhancement in productivity through a reduction in the number of processes and a reduction in processing time is disclosed. In the aluminum plate manufacturing method, a plate is rolled after being extruded to a desired thickness. Accordingly, it is possible to reduce the number of processes and a processing time and, as such, achieving an enhancement in productivity, as compared to a conventional manufacturing process using only rolling.
