摘要： A continuous casting and rolling line for casting, rolling, and otherwise preparing metal strip can produce distributable metal strip without requiring cold rolling or the use of a solution heat treatment line. A metal strip can be continuously cast from a continuous casting device and coiled into a metal coil, optionally after being subjected to post-casting quenching. This intermediate coil can be stored until ready for hot rolling. The as-cast metal strip can undergo reheating prior to hot rolling, either during coil storage or immediately prior to hot rolling. The heated metal strip can be cooled to a rolling temperature and hot rolled through one or more roll stands. The rolled metal strip can optionally be reheated and quenched prior to coiling for delivery. This final coiled metal strip can be of the desired gauge and have the desired physical characteristics for distribution to a manufacturing facility.

摘要： An aluminum alloy sheet for motor vehicles is produced by casting a melt, containing 3.0-3.5 mass % Mg, 0.05-0.3 mass % Fe, 0.05-0.15 mass % Si, and less than 0.1 mass % Mn, a balance substantially being inevitable impurities and Al, into a slab having a thickness of 5 to 15 mm in a twin-belt caster so that cooling rate at ¼ depth of thickness of the slab is 20 to 200° C./sec; winding the cast thin slab into a coiled thin slab subjected to cold rolling with a roll having a surface roughness of 0.2 to 0.7 μm Ra at a cold rolling reduction of 50 to 98%; subjecting the cold rolled sheet to final annealing either continuously in a CAL at a holding temperature of 400 to 520° C. within 5 minutes or in a batch annealing furnace at a holding temperature of 300 to 400° C. for 1 to 8 hours; and subjecting the resulting sheet to straightening with a leveler.

摘要： Embodiments of the invention relate to a method and apparatus for continuously casting a metal slab. The method involves continuously introducing molten metal into an inlet of a casting cavity defined between advancing casting surfaces, cooling the metal in the cavity to form a metal slab, and discharging the slab from the cavity through an outlet. The casting surfaces have an ability to remove heat from the metal but this ability is reduced, thus reducing heat flux, for at least one of the casting surfaces in a region of the cavity spaced from both the inlet and the outlet and extending transversely to the casting direction. This reduced ability to remove heat is relative to such ability of the casting surface in immediately adjacent upstream and downstream regions of the cavity. The apparatus may be a twin belt caster or other form of continuous caster modified to perform the method.

摘要： Exemplary embodiments of the invention provide a side dam for a continuous metal casting apparatus having elongated opposed casting surfaces forming a casting cavity. The side dam has an elongated upstream part and an elongated downstream part that are mutually laterally pivotable, and a smooth metal-contacting side surface extending continuously from an upstream end to a downstream end of the side dam. The surface has regions thereof formed on the upstream part and the downstream part. Mutual pivoting of the upstream part and the downstream part of the side dam enables the regions of the smooth metal-contacting side surface to be moved out of mutual coplanar alignment. The side dams can therefore be used to form either a convergent or divergent casting cavity to assists the casting procedure and to enhance the properties of the cast article.

摘要： Exemplary embodiments of the invention provide a method of measuring the separation of moving confronting casting surfaces within a casting cavity of a casting apparatus. The method involves attaching at least one separation sensing device to a first one of a pair of confronting casting surfaces outside the casting cavity and then moving the casting surfaces to advance the sensing device(s) through the casting cavity while operating the device(s) to generate signals. The signals are monitored continuously or at regular intervals and converted to distance measurements representing separation of the surfaces at a plurality of positions through the casting cavity. Other exemplary embodiments provide apparatus for carrying out the method, and methods of measuring irregularities of casting belts or the like.

摘要： A twin-belt casting machine for casting metal strip. The machine is provided with a casting cavity which includes an upstream fixed casting region, in which the belts are in fixed convergent paths in contact with the cast slab, and an adjacent downstream portion in which the belts are adjustable between alignment with the fixed convergent paths and non-alignment therewith (being less convergent or divergent). When the adjustable portions of the paths are moved outwardly relative to the fixed convergent paths, the belts separate from the cast slab at differing predetermined points within the casting cavity. By adjusting the downstream portion of the casting cavity in this manner, the casting machine can operate at essentially constant throughput for a wide range of alloys while ensuring that the cast slab exiting the caster has a temperature within a predetermined range suitable for further rolling to produce sheet product.
