摘要： Described herein is a method for rolling metal sheets of variable thickness. The method makes it possible to impress, during rolling, any distribution of areas of increased thickness within a figure corresponding to the plane development of a motor-vehicle component prior to the pressing operation. Impression of the desired distribution of areas of increased thickness envisages simultaneous impression, during rolling, of a further distribution of areas of increased thickness, or compensation areas.

摘要： A method for producing a strip consisting of aluminum or an aluminum alloy for packaging purposes, in particular for cans, can lids or can closures, which provides an individualized aluminum strip for packaging purposes, with which decorative or identification elements can be reliably embossed without additional production steps being required, for example at the producer of the packaging means, is achieved in that decorative or other identification elements are embossed into the strip in the last rolling pass of cold rolling and in that the strip thickness is greater in the area of the decorative and identification elements than in the remaining areas of the strip.

摘要： The present invention relates to a method for manufacturing a component of austenitic TWIP or TRIP/TWIP steel. A flat product (1) is deformed by achieving at least one indentation (16) on at least one surface of the flat product (1) in order to have in the deformed product (5) areas of a high strength steel embedded in a matrix of a ductile material. The invention also relates to the use of the component where areas of a high strength steel embedded in a matrix of a ductile material are required in the same component.

摘要： A bar of noble metal or an alloy containing noble metal having a mass mB is subdivided into n×m miniature bars 2, 3 each having a specified mass mk, wherein n and m each denote an integer ≧2, there being an interconnection of solid material (8) between directly adjacent miniature bars (2, 3). Another bar is affixed to a backing (13), to which the miniature bars are releasably attached. A method for the production of the bar consists in dividing up the same while leaving an interconnection of solid material or producing an arrangement thereof on a backing.

摘要： In a method of using a closed, extruded profile, developing a hollow profile and producing a stepped cross-sectional metal sheet with different wall thicknesses, the profile or the hollow profile is used as a starting material for rolling. The hollow profile has only one wall, which turns back in on itself in the peripheral direction without branching and is of different thicknesses at different points of the periphery. The hollow profile is separated along a surface line, is formed into the semifinished article and is subsequently rolled to produce the metal sheet.

摘要： A process for producing a flat heat exchange tube having parallel refrigerant passages in its interior and comprising flat upper and lower walls, opposite side walls and a plurality of reinforcing walls connected between the upper and lower walls, extending longitudinally of the tube and spaced apart from one another by a predetermined distance, using a rolling mill including a central work roll and a plurality of planetary work rolls arranged around a portion of the periphery of the central work roll and spaced apart circumferentially thereof, the central work roll being formed with parallel annular grooves in the periphery thereof. An aluminum sheet blank including a brazing sheet is rolled by the mill and thereby thinned to a predetermined thickness to form a flat portion serving as the lower wall, cause the annular grooves at opposite roll ends to form upright portions providing the respective side walls and the other annular grooves to form vertical ridges providing the reinforcing walls, the upright portions and the vertical ridges projecting from the flat portion integrally therewith. An aluminum sheet comprising a brazing sheet is placed over all the ridges to provide the upper wall and joined to the upright portions to make the upright portions serve as the opposite side walls, and the ridges of the lower wall are joined to the upper wall to form the reinforcing walls.

The reinforcing walls are each formed with communication holes for causing the parallel refrigerant passages to communicate with one anther therethrough. The flat aluminum tube is prepared from upper and lower two aluminum sheets by bending opposite side edges of the lower aluminum sheet to a raised form and joining the bent edges to the respective side edges of the upper aluminum sheet which is flat so as to form a hollow portion. The reinforcing walls are formed by joining to the inner surface of the upper wall ridges projecting inward from the lower wall. The communication holes are formed by cutouts formed in the edges of the ridges at a predetermined spacing and having their openings closed with the upper wall.
