  • SYSTEMS AND METHODS FOR CONTROLLING SURFACE TEXTURING OF A METAL SUBSTRATE WITH LOW PRESSURE ROLLING
    Publication number: 20190022721
    Abstract: Systems and methods of applying a texture on a substrate include applying a texture to the substrate with a work stand of a coil-to-coil process. The work stand includes an upper work roll and a lower work roll vertically aligned with the upper work roll. At least one of the upper work roll and the lower work roll includes the texture. Applying the texture includes applying, by the upper work roll and a lower work roll, a work roll pressure on an upper surface and a lower surface of the substrate. The method further includes adjusting a contact pressure parameter of the work stand such that the work stand provides a desired contact pressure distribution across the width of the substrate and a desired thickness profile of the edges of the substrate while an overall thickness of the substrate remains substantially constant.

  • MICRO-TEXTURED SURFACES VIA LOW PRESSURE ROLLING
    Publication number: 20190022720
    Abstract: A substrate (e.g., metal or non-metal sheet) can have multiple textures on a surface of the substrate. The various textures can be impressed or applied on the surface of the substrate by passing the substrate between multiple pairs of work rolls that each include at least one textured work roll for transferring a texture of the work roll onto the surface of the substrate. The pairs of work rolls apply the various textures on the surface of the substrate while maintaining a thickness of the substrate (e.g., with substantially no reduction in a thickness of the substrate). A single pass of the substrate between the pairs of work rolls can allow various different textures, patterns, or features to be applied to the surface of the substrate while the thickness of the substrate remains substantially constant.

  • Process damping of self-excited third octave mill vibration
    Patent number: 10166584
    Abstract: Control of self-excited third octave vibration in a metal rolling mill can be achieved by adjusting the tension of the metal strip as it enters a stand. Self-excited third octave vibration can be detected and/or measured by one or more sensors. A high-speed tension adjustor can rapidly adjust the entry tension of the metal strip (e.g., as the metal strip enters a mill stand) to compensate for the detected self-excited third octave vibration. High-speed tension adjustors can include any combination of hydraulic or piezoelectric actuators coupled to the center roll of a bridle roll to rapidly raise or lower the roll and thus induce rapid tension adjustments in the strip. Other high-speed tension adjustors can be used.

  • Flatness of a rolled strip
    Patent number: 10130979
    Abstract: A method for improving the flatness of a rolled sheet or strip includes the application of differential cooling. A cooling agent can be selectively applied along the width of the strip. More cooling can be applied to the edges of the strip, where tension is greatest, to increase tension at the edges. The strip can be allowed to lengthen at these edges, which can improve flatness. In some embodiments, a closed loop flatness control system is used to measure the flatness of a strip and automatically adjust the differential cooling based on the measurement.

  • SURFACE ROUGHENING OF POLYMER FILMS
    Publication number: 20180281377
    Abstract: The surface roughness of a polymer film laminated to a metal substrate can be improved through the use of sufficient heating after application of a wax layer to the polymer film. In some cases, a thin liquid film or layer of a waterborne wax dispersion can be applied to the surface of a metal substrate laminated with a polymer film. After heating the polymer film and wax layer to a point at which the polymer film and wax layer begin to become molten, the surface roughness of the polymer film can become improved due to the presence of the wax.
