摘要： A method and apparatus are described for the casting of a composite metal ingot having two or more separately formed layers of one or more alloys. An open ended annular mould is provided having a divider wall dividing a feed end of the mould into at least two separate feed chambers. For each pair of adjacent feed chambers, a first alloy stream is fed through one of the pair of feed chambers into the mould and a second alloy stream is fed through another of the feed chambers. A self-supporting surface is generated on the surface of the first alloy stream and the second alloy stream is contacted with the first stream. By carefully selecting conditions and positions where the alloy streams meet, a composite metal ingot is formed in which the alloy layers are mutually attached with a substantially continuous metallurgical bond.

摘要： A composite metal ingot having two or more lengthwise alloy layers including adjacent first and second layers respectively formed of an aluminum-manganese alloy and an aluminum alloy of a different composition wherein the interface between the first and second layers is in the form of a substantially continuous metallurgical bond characterized by the presence of particles of one or more intermetallic compositions containing manganese from the first layer dispersed within a region of the second layer adjacent the interface, the first and second layers having been formed by applying the alloy for the second layer to a self-supporting surface of the first layer while the self-supporting surface is at a temperature between the solidus and liquidus temperatures of the first layer alloy.

摘要： A method of casting a metal ingot with a microstructure that facilitates further working, such as hot and cold rolling. The metal is cast in a direct chill casting mold, or the equivalent, that directs a spray of coolant liquid onto the outer surface of the ingot to achieve rapid cooling. The coolant is removed from the surface at a location where the emerging embryonic ingot is still not completely solid, such that the latent heat of solidification and the sensible heat of the molten core raises the temperature of the adjacent solid shell to a convergence temperature that is above a transition temperature for in-situ homogenization of the metal. A further conventional homogenization step is then not required. The invention also relates to the heat-treatment of such ingots prior to hot working.

摘要： A method and apparatus is disclosed for sequentially direct chill casting a composite ingot made of metals having similar freezing ranges. Poor adhesion between the layers and low reliability of casting are addressed by adjusting the position of secondary cooling (created by applying water streams to the emerging ingot) relative to the upper surfaces of the molten metal pools compared to the conventional positions of first application of the secondary cooling. This can be achieved by moving one or more walls of the mold (when the secondary cooling emanates from the bottom of such walls), or adjusting the height of the molten metal pools within the mold and moving cooled divider walls between the pools. The relative temperatures and conditions of the metals at positions where they meet at the metal interface may therefore be optimized.
