  • Rolling (metalworking) Wikipedia

    Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

  • 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.

  • What is a Reversing Mill? Definition from Corrosionpedia

    Reversing mills are also known as reversing cold rolling mills. Corrosionpedia explains Reversing Mill. In a reversing mill, steel enters the rolling mill from one side, passes through the other side and then comes back through the mill again. Normally it goes left to right through the mill a number of times, being rolled a little thinner each time it goes through. Rolling mills can use two

  • Walzen Wikipedia

    Walzen ist ein Fertigungsverfahren aus der Gruppe des Druckumformens, bei dem der (meist metallische) Werkstoff zwischen zwei oder mehreren rotierenden Werkzeugen umgeformt und dabei dessen Querschnitt verringert wird. Findet die Umformung oberhalb der Rekristallisationstemperatur des Werkstoffs statt, wird sie Warmwalzen genannt, sonst Kaltwalzen.
