1) Rolling: To reduce thickness. 2) Annealing: To restore ductility. 3) Slitting: To separate a wide strip into narrower cuts. The rolling process generally begins with material in the annealed condition. The condition of metal (e.g. annealed, tempered) can be defined by the grain structure, or, microscopic structure (microstructure) of that ...

What Is a Rolling Mill? At its most basic principle, a rolling mill is a machine that reduces the thickness of a metal without sacing any of the material – meaning material is always displaced and never lost. By design and function, rolling mills do not generate scrap. The process of rolling affects the materials at a metallurgical level ...

The maximum axial load is 580.4 kN for a 4-roll mill and 455.1 for a 3-roll mill. An interesting fact is the occurrence of a negative load acting on the chuck when the biggest diameter steps are formed. This indicates that the rolling process runs on an independent basis and that the chuck prevents the axial movement of the workpiece.
