Abstract: A continuous extrusion machine has a chassis (1) supporting a wheel (2) for rotation by a motor. An endless groove (7) extends around the periphery of the wheel (2). A shoe (3) is mounted in the chassis (1) and has an enveloping surface shaped to closely envelop an arc of the wheel (2) periphery so that the groove (7) co-operates with the shoe (3) to form a passage. An abutment is mounted on the shoe (3) to extend into the passage at a downstream end. Tooling is mounted in the shoe (3) including a die such that a material such as aluminium or copper bar fed into the groove (7) is extruded through the die as a consequence of the energy transfer via friction from the rotating wheel (2). A gap (12) exists between the enveloping surface and the wheel (2). The gap (12) is used to provide the orifice of a sonic gap (12) sensor whereby the size of the gap (12) can be accurately and directly measured.

Abstract: The invention relates to a method for producing metal shapes with a partially or totally polygonal cross-section by means of continuous casting in a double-flanged wheel and continuous rolling using a series of at least 3 pairs of rollers with a peripheral flange, whereby said rollers are alternately horizontally and vertically disposed in a symmetrical position with respect to said shape.

Abstract: A method and apparatus are provided for rapid production of high-strength metal structures. A computerized model of the structure is created, then the model is sliced into horizontal layers. A computer-controlled gantry controls the location of a roller in at least three axes (x, y, and z), the roller depending from the gantry. An electron or laser beam melts the end of a metal wire, forming a puddle of molten metal near the roller. Coordinates defining each layer of the model of the component are sent to the gantry, which moves the roller over the puddle to create a uniform-thickness layer, the wire feeding additional metal to be melted by the beam as the gantry moves. The puddle is narrow, typically requiring multiple narrow strips to be laid adjacent each other to form a complete layer. When a layer is completed, additional layers are formed on the first layer, and this process repeats until the structure is completed.

Abstract: A layer of liquid parting agent, and any solid detritus contained therein, is completely removed from a casting surface of a rotating belt after contact with molten metal. A new layer of liquid parting agent is applied to the casting surface thereafter and prior to renewed contact with the molten metal. The removal of used parting agent and the application of fresh helps to prevent the formation of surface blemishes and defects on the cast metal strip product. Such blemishes and defects can also be minimized by using an injector having a flexible tip used to inject the molten metal onto the casting surface and preferably one or more spacers to create a gap between the tip and the casting surface itself. The spacer is preferably a screen of wire strands orientated to minimize disruption of the new layer of liquid parting agent applied to the casting surface. By avoiding disruption of the new layer of liquid parting agent, surface blemishes on the cast product are minimized.

Abstract: A method of manufacturing strips, bars and wire rods comprises continuously supplying molten metal into an open-top endless casting groove on an annular mold that is rotated around a vertical shaft, cooling the molten metal in the casting groove from outside by forcibly cooling the annular mold, and continuously taking out the cast section from the casting groove at a point where a solidified shell has been formed throughout the entire circumference of the molten metal in the casting groove. A roll is provided upstream of the take-out point to depress the top surface of the cast section, thereby keeping the cast section in close contact with the surface of the casting groove. The cast section then slides diagonally upward over a surface inclined at an angle of 5 to 60 degrees that is provided on the exit side of the above roll in the casting groove.

Abstract: The casting wheel of a continuous casting machine is cooled by a conventional external spray cooling system, but the continuous band looped around the casting wheel to close a predetermined segment of it and thereby form a continuous moving mold cavity is not directly cooled. Rather, the band incorporates a layer of heat-insulative sheet material to deter heat transfer from molten metal introduced into the mold cavity through the band. The result is that the metal solidifies in a direction generally radially outward from the casting wheel toward the insulated band. Shrinkage of the metal occurs primarily adjacent to the band so as to eliminate or reduce internal shrinkage cracks and voids.

Abstract: In a device for continuous casting that uses a casting wheel (5) molten material is fed into a recess that runs around the outer periphery of the casting wheel in tangential direction, the recess being open to the outside. During the rotational movement of the casting wheel the material hardens partially in the recess, with the formation of a solid skin. At least in the section up to the formation of the solid skin the recess is closed off by an endless steel strip (6) that passes over guide rollers (7,8,9), the strip (6) being pressed against the casting wheel. The application force for the steel strip is exerted by a chain (11) that is arranged--viewed from the casting wheel--in the pressure area behind the steel strip. This chain is subjected to a corresponding tensile force. To this end, one (10) of the guide rollers (8,9,10) for the chain is installed so as to be movable and subjected to a force that generates the tensile force in the chain.
