  • Patent number: 10493508
    Abstract: 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.

    Abstract: The invention relates to the field of pressure treatment of metals and can be used in the production of a cold-rolled strip. The problem addressed by the invention is that of being able to exclude a pickling operation in the preparation of semifinished rolled stock for cold rolling. Complete de-scaling of the surface of the semifinished rolled stock without using picking is provided by carrying out preliminary cold rolling of the semifinished rolled stock in rolling-mill rolls according to prescribed values for compression and for the ratio of compression to deformation zone length. The rolling can be carried out in one of two consecutively mounted mills.

  • Publication number: 20140335369
    Abstract: The process of forming a partial gold-plating pattern on a stainless substrate includes a first plating step, a second plating step, and a stripping step. In the first plating step, pretreatment is applied to a stainless substrate including opposite main planes and a processing site formed of a plane different from the main planes, after which a first gold-plating layer is formed all over the surface of the stainless substrate using a hydrochloric acid plating solution. In the second plating step, mask plating is used to form a second gold-plating layer on the first gold-plating layer that covers the processing site in a desired pattern, and in the stripping step, a portion of the first gold-plating layer in an area where there is none of the second gold-plating layer is stripped off using an alkaline stripping solution.

  • Publication number: 20140302341
    Abstract: In a hot press molding method for press-molding a heated material and cooling the material while holding the material in a mold, during press molding of the material, shape changes including a portion that curves with respect to a longitudinal direction of the material are molded at longitudinal opposite end portions of the material and resistance to thermal contraction force of the material in the longitudinal direction during cooling is imparted. In one embodiment of the present invention, the shape changes molded on the material during the press molding are minute protrusions provided on surfaces of the longitudinal opposite end portions of the material. The invention makes it possible to suppress thermal contraction of the material during cooling in hot press molding to thereby prevent defects associated therewith.

  • Publication number: 20140295205
    Abstract: A hot press-forming method includes a forming step that clamps a steel sheet heated to a temperature not less than an austenite transformation temperature and press-forms the steel sheet into a desired shape by causing a forming concave of a die and a convex of a punch to be close to each other. A formed portion has side and top portions that merge. The side portion rises up from an inner circumferential edge of a flange portion having been clamped by the die and the blank holder. A cooling step cools a region of the steel sheet after the heating step has been completed and before the forming step is completed. The particular region is along an inter-edge area formed between an opening circumferential edge of the forming concave and a top circumferential edge of the forming convex before the forming step is completed.

  • Publication number: 20140248506
    Abstract: Techniques for graphic formation via material ablation described. In at least some implementations, a graphic is applied to a surface of an object by ablating layers of the object to form an ablation trench in the shape of the graphic. In at least some embodiments, an object can include a surface layer and multiple sublayers of materials. When an ablation trench is generated in the object, the ablation trench can penetrate a surface layer of the object and into an intermediate layer. In at least some implementations, height variations in an object surface caused by an ablation trench can cause variations in light reflection properties such that a graphic applied via the ablation trench appears at a different color tone than a surrounding surface, even if the ablation trench and the surrounding surface are coated with a same colored coating.
