摘要： A planishing roll has a surface structure, in particular for producing flat products from a metallic material, in particular from a steel material. The surface structure has a material ratio of 2% at a depth of 0.2 μm to 9 μm, preferably at a depth of 0.8 μm to 5.5 μm. The depth is measured, starting from a zero line, in the direction of an axis of rotation of the planishing roll, with the zero line running parallel to the axis of rotation of the planishing roll and. Starting from the surface of the planishing roll, the zero line is displaced in the direction of the axis of rotation of the planishing roll until the material ratio of the planishing roll is 0.1%.

摘要： The invention relates to a method for manufacturing profiled metal strips (1, 1′), in which a metal strip (1, 1′) with predefinable material thickness consisting, in particular, of stainless steel is wound up on a coil (4) and guided through a rolling stand (W1-W4) containing several rolls (2, 3, 2′, 3′), wherein at least the rolls (2, 3) that effectively interact with the metal strip (1, 1′) are provided with a predefinable topography (8, 9), by means of which profiles with profile depths >250 μm can be produced on both sides of the metal strip (1, 1′) depending on the geometry of the topography (8, 9) of the rolls (2, 3), and wherein the metal strip (1, 1′) is subsequent to its profiling wound up on a coil (5) and, if so required, subjected to a thermal post-treatment.

摘要： A textured work roll can impart a desired texture on a metal substrate, such as an aluminum or aluminum alloy sheet. The textured work roll can be used for applying a gloss finish on the metal substrate. The textured work roll can be textured by grinding the work roll to form a ground work roll; electro-discharge texturing the work roll to form an electro-discharge textured work roll; and polishing the work roll to form a polished work roll. The polished work can have an Ra value between 0.30 μm and 0.70 μm. The polished work roll can be used to apply the gloss finish on the metal substrate.

摘要： Method for producing an aluminum foil with integrated security features. An aluminum foil is rolled down to a thickness of less than 150 μm in a plurality of cold rolling passes, texturing that runs in the direction of rolling being induced simultaneously on both surface sides of the foil. In a final cold rolling pass, the foil is fed to a working roller pair, in which, on at least one roller surface, the relief-like surface structuring generated in the rolling direction by grinding was reduced on the basis of contrast and motif in a region of 10 to 50% relative to the average surface roughness to form a motif for a security feature that is transferred to the surface side of the foil facing the roller surface. The generated aluminum foil has a glossy appearance on both sides such that the security feature rises clearly due to its dull appearance.

摘要： Metal work rolls texturized with engineered textures can impart desired impression patterns on metal strips. Engineered textures can be controlled with particularity to achieve desired surface characteristics (e.g., lubricant trapping, coefficient of friction, or surface reflectivity) on work rolls and metal strips, and to allow for impression patterns to be imparted on metal strips during high percentages of reduction of thickness (e.g., greater than about 5% or greater than about 15%, such as around 30%-55%). Engineered textures can be applied by focusing energy beams at specific points of an outer surface of a work roll to impart texture elements on the work roll. In some cases, an engineered texture element that can be used to generate a generally circular impression element can be generally elliptical in shape, having a length that is shorter than its width by a factor dependent on the reduction of thickness percentage.

摘要： A roller for forming heat transfer elements may include a central shaft and a plurality of roller elements. The plurality of roller elements may be stacked on the central shaft. Each roller element defines an outer periphery, which is configured to include a geometrical characteristic thereacross. The stacked roller elements, either stacked on the central shaft or stacked without using the central shaft, configures the roller with a circumferential surface corresponding to the geometrical characteristic of the stacked roller elements, to form the heat transfer elements corresponding to the circumferential surface.
