Tags Rolling Mills; What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

The 20 high rolling mill from ANDRITZ Sundwig is mainly used for cold rolling of metal strip to thinnest final gages and wide range of strip width. The special feature in a 20 high mill is the relation between work roll diameter and barrel length.

G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 11.5.1 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic – ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4-high) both roll force ...
