SENDZIMIR STEEL MILL. DISTRIBUTION OF WORK ROLLS. SENDZIMIR BACK-UP ROLLER (SECTION) Among the multi-cylinder rolling mills, the best known is the Sendzimir rolling mill, used for the rolling of the strips. It consists of a pair of large diameter cylinders on whose circumference other small diameter cylinders (planetary) are located, which are ...
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 ...

Nisshin Steel Co. placed the world's first Sendzimir tandem mill into operation at ts Shunan works in 1969. Located in Nanyo, Japan, the plant occupies a site of approximately one-thir d square mile. Occupying about 18 percent of the 315-ft total installation length are f our Sendzimir stands: one ZR 22N-50 and three ZR 21B-50. Once up and running, the mill's maximum finished monthly ...
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 ...

Before Nisshin Steel's 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

Tandem hot strip mills were, and are still being, constructed in numbers in China and some other countries, and many of these latest hot strip mills have quality improvement measures such as coil boxes. Although inferior in productivity to a tandem hot strip mill, a Steckel mill requires smaller capital investment and offers wider free-
