A Zmill is a machine for rolling steel. It allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality. The Zmill uses cascaded supporting rolls instead of using a single pair of rolls to apply force on the small work rolls in the center. The Zmill is designed to make heavy ...
