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.
