    摘要： The present invention provides continuous casting-milling equipment and method capable of switching between continuous and batch milling, which increase the process yield rate by reducing the portion which is unavoidably processed as scrap, when switching casting or at an initial stage. The continuous casting-milling equipment comprises: a casting unit; at least two rolling units; and a coil box arranged between the rolling units. The continuous casting-milling method comprises: a casting step for producing a slab; a first rolling step which reduces the thickness of the slab; a cutting step of cutting a predetermined distance from a front end portion of the slab at the initial stage of casting; a passing step of passing the continuously supplied slab through the coil box; and a second rolling step which reduces the thickness of the passed slab.

    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.
