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.

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： When the starter block commences reciprocating along the axis of an open ended mold cavity, with a body of start up material in tandem with it, successive layers of molten metal are relatively superimposed on the body of start up material, and layers thereof are confined to a first cross sectional area of the cavity but permitted to distend relatively peripherally outwardly from the circumferential outline of the first cross sectional area at relatively peripherally outwardly inclined angles to the axis while thermal contraction forces are generated in the respective layers and the magnitude of the forces is controlled so that the thermal contraction forces counterbalance the splaying forces in the respective layers and confer a free-formed circumferential outline on the resulting body of metal as it becomes form-sustaining.

摘要： Exemplary embodiments of the invention relate to a compressive rod assembly for applying force to a refractory vessel positioned within an outer metal casing. The assembly includes a rigid elongated rod having first and second opposed ends, a threaded bolt adjacent to the first opposed end of the elongated rod, and a compressive structure positioned operationally between the elongated rod and the bolt. Compressive force applied by the bolt to the elongated rod passes through the compressive structure which allows limited longitudinal movements of the elongated rod to be accommodated by the compressive structure without requiring corresponding longitudinal movements of the bolt. Exemplary embodiments also relate to rod structure forming a component of the assembly, and to a metal containment structure having a vessel supported and compressed by at least one such assembly.

摘要： A method and apparatus for casting metals in a DC mold to form an ingot or product having at least two layers formed by sequential solidification. The apparatus has at least one cooled divider wall at the entry end portion of the mold to divide the entry end portion into at least two feed chambers. Metal is fed to the chambers to form an inner layer and at least one outer layer. The divider wall has a metal-contacting surface for contacting the metal for the at least one outer layer, the surface being arranged at an angle to the vertical sloping away from the metal for the outer layer in a downward direction. The angle increases at positions on the divider wall spaced from a central section of the wall approaching each longitudinal end thereof. The apparatus is suitable for casting a metal having a high coefficient of contraction as an inner layer or core ingot, e.g. a high-Mg or high-Zn aluminum alloy, or metal combinations having a large difference in their coefficients of contraction.

摘要： When a body of startup material has been interposed in the cavity between the starter block and a first cross sectional plane of the cavity transverse the axis thereof, the starter block has commenced reciprocating along the axis, and the body of startup material has commenced reciprocating in tandem with it, through a series of second cross sectional planes, layers of molten metal are successively superimposed on the body of startup material adjacent the first cross sectional plane of the cavity, and the layers promptly distend relatively peripherally outwardly from the axis under the inherent splaying forces therein. The invention confines the relatively peripheral outward distention of the layers with a casting surface which is peripherally outwardly flared about the axis of the cavity. Initially, at the circumferential outline of the cross sectional area circumscribed by the surface in the first cross sectional plane of the cavity, the casting surface directs each of the layers into the series of second cross sectional planes at relatively peripherally outwardly inclined angles to the axis. Then the surface allows the layer to assume second cross sectional areas whose cross sectional dimensions undergo continual enlargement peripherally outwardly of the axis, so that the thermal contraction forces arising in the layer can counterbalance the splaying forces while the layer freeforms with the other layers into a body of metal at one of the second cross sectional planes of the cavity.

摘要： The mold has a first chamber defined by a pair of inner and outer peripheral walls circumposed about the axis of the cavity and spaced apart from one another transverse the axis. The first chamber has oppositely disposed end walls that extend transverse the axis and an inlet for the supply of liquid coolant under pressure. The inner peripheral wall has a step which projects into the first chamber. The step has a first surface that extends transverse the axis and a second surface that extends parallel to the axis and coterminates with the first surface to form a corner. A second chamber is formed in the inner peripheral wall at the step. A series of holes open into the first chamber at one of the surfaces of the step to permit coolant to discharge into the second chamber at a reduced pressure. A passage opening discharges the reduced pressure coolant onto a body of metal emerging from the discharge end opening of the cavity.
