Sendzimir Products 20-High Mills

20-High Mills. Sendzimir's 20-High mills are unique in that they have a small, chockless work roll and a cluster roll configuration supported by the Backing Assemblies. The cluster configuration transmits the roll separating force from the work rolls to the mill housing. The small size of the work roll permits superior reductions on very hard materials, such as stainless steel or titanium ...

Sundwig 20-High cold rolling mill - ANDRITZ

The history of the Sundwig 20-high rolling mill begins in the first half of the last century, when Sundwig developed a multi-roll cold rolling mill in 1930. Just a few years later, the first alligator-type 20-high rolling mill was built, followed in 1958 by the first 20-high rolling mill in Sundwig Four Column (SFC) design. Since then, ANDRITZ Sundwig has continued to develop 20-high rolling ...

Plate Shape Control Theory and Experiment for 20-high

01/11/2015  The 20-high mill rolls are set as a cluster, as shown in Fig. 3. In order to analyze roll deformation, force analysis should be carried out for the special structure of rolls, and then the force equilibrium, deflection deformation, torque equilibrium, and displacement coordination function can be established. In Fig. 3, α1-α7 are the angles between rolls center connection and horizontal ...

Z-mill - Wikipedia

A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20-high cluster mill configuration 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.
