Z-mill
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. Thus very hard and elastic materials can be rolled. == Development == The evolution to the current 20-High Cluster Sendzimir Mill from the early 12-High configuration was pioneered by Tadeusz Sendzimir in the early 1930's. The designs for the Sendzimir Mill were perfected and patented by Tadeusz's company T. Sendzimir, Inc. Significant design improvements were made by (T. Sendzimir, Inc ). including the flexible shaft backing assemblies and segmented idler rolls, as well as tapered edge intermediate rolls with lateral adjust for superior shape control. With advent of Finite Element Analysis technology T. Sendzimir, Inc. iterated the mono-block housing design to create the Zero Crown Housing solution. This reduced the amount of material required for the housing, while creating uniform elastic deformation across the housing during rolling in order to maintain a better shape profile of the strip.
