How Meny Reduction For High Roling Mill

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.

2-High Rolling Mills | Metal Processing ... - American Steel

A 2-high mill can make a slight reduction and lay the material out flat and uniform.
