  • Patent number: 11911815
    Abstract: A strip of metal entering or exiting a mill can be redirected about a roller so as to define an angled segment of the strip of metal, with the angled segment extending away from the roller and arranged at an angle relative to the roller. The angled segment can be connected with a coil that is rotated about a mandrel such that a magnitude of the angle of the angled segment changes as the coil is enlarged or reduced by the rotating of the mandrel. A sensor of a surface inspection system can detect a characteristic of a surface of the strip of metal in the angled segment or in the coil. The sensor can be robotically moved to modify a distance and/or an orientation of the sensor of the surface inspection system relative to the surface.

  • Publication number: 20230193441
    Abstract: A system for heat-treating a coil of metal can include a furnace, an unwinding system, and a quenching system. The furnace may receive the coil of metal and elevate a temperature of the metal to be within a pre-heated temperature range, such as a homogenizing temperature range or an annealing temperature range. The unwinding system may unwind at least a portion of the coil in a heated state in which the metal is within the pre-heated temperature range or before the metal has cooled past a threshold amount below the pre-heated temperature range. The quenching system may receive the unwound portion of the coil from the unwinding device and reduce a temperature of the unwound portion to a within a quenched temperature range within a predetermined amount of time.

  • Patent number: 10953447
    Abstract: Provided herein are systems and methods for containing a viscous material, such as a coolant, on a roll and/or a roll processed engineering material (e.g., a metal strip). In particular, a viscous material containment system can include a movable seal and a gas delivery device. A method for cooling a roll can include applying a viscous material, such as a coolant, to the roll and containing the viscous material on the roll using the viscous material containment system. In some cases, the viscous material containment system can be used to facilitate removal of the viscous material from the roll and/or the roll processed engineering material.

  • Patent number: 10814365
    Abstract: Provided herein are systems and methods for containing a viscous material, such as coolant, applied to cool a roll or a roll processed engineering material such as a metal strip. In particular, a viscous material containment system can include a housing, a viscous material delivery system, a plurality of movable seals and a plurality of gas delivery devices. A method for cooling a roll can include applying a vicious material, such as coolant, to the roll and containing the viscous material on the roll using the viscous material containment system. In some cases, the viscous material containment system can be used to facilitate removal of the viscous material from the roll.

  • Publication number: 20170165728
    Abstract: 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 ?m and 0.70 ?m. The polished work roll can be used to apply the gloss finish on the metal substrate.
