    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 rolls in the center. This allows the application of a higher roll pressure without bending the rolls, which would result in poor metal quality.
