Crown control roll
WebJul 9, 2014 · A 3D elastic–plastic finite element method (FEM) model of cold strip rolling for 6-high continuous variable crown (CVC) control rolling mill was developed. This model considers the boundary conditions such as accurate CVC curves, total rolling forces, total bending forces and roll shifting values. WebRoll forming, roll bending or plate rolling is a continuous bending operation in which a long strip of metal (typically coiled steel) is passed through consecutive sets of rolls, or …

WebUsing a single work roll crown makes the flatness control very inflexible, as the roll is perfect for only one roll deflection and strip crown. It is common to use a few different work roll crowns for different rolling situations. An actuator to dramatically increase the flexibility is work roll bending.
