Z-mill - Wikipedia

A Z-Mill or Sendzimir Mill is a machine for rolling steel.[1][2] 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 appliion of a higher roll pressure without bending the work rolls, which would result in poor
