The paper compares and contrasts various controller possibilities and is intended to provide a "cookbook" of shape control tools and strategies for Sendzimir mills. Deals with the problem of shape (or flatness) control for Sendzimir 20-roll cold-rolling steel mills. Such mills, with a variety of shape actuators, offer the control engineer considerable choice in the configuration and design of ...

Small Tandem Mill. Before nisshin steels tandem mill was even considered, only a few sendzimir mills in the world were being used to reduce or skinpass strip on a once-through basis.most sendzimir cluster mills were being used in a series of reversing operations.sendzimir has developed several mill arrangements, but the dominant layout is the 1-2-3-4.
Unlike a traditional rolling mill, a Z-High® mill is a 20-high cluster mill configuration that utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality. As a result, very hard and ...
