mechanical engineering: Types of rolling mills

In two high reversing rolling mills the rolls rotate ist in one direction and then in the other, so that rolled metal may pass back and forth through the rolls several times. This type is used in pluming and slabing mills and for roughing work in plate, rail, structural and other mills. These are more expensive compared to the non reversing rolling mills. Because of the reversible drive ...

Corrosionpedia - What is a Reversing Mill? - .

Rolling mills can use two, three or four rolls. In two-high reversing rolling mills, the rolled metal may pass back and forth through the rolls several times. The disadvantage of reversing mills is that the rolls must be stopped, reversed and then brought back up to rolling speed between each pass. The three-high mill was invented to resolve this drawback. Reversing mills are more expensive ...

a typical value is around 0.2; and in hot rolling, m is around 0.4. Hot rolling is often characterized by a condition called sticking, in which the hot work surface adheres to the rolls over the contact arc. This condition often occurs in the rolling of steels and high-temperature alloys. When sticking occurs, the

Rolling (metalworking) - Wikipedia

These backup rolls are larger and contact the back side of the smaller rolls. A four-high mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils.

Classification of Rolling mills – IspatGuru

Hot rolling mills – In these mills, rolling is done above the recrystallization temperature of the metal. During rolling in these mills the grains, which deform during the process of rolling, recrystallize, maintain an equiaxed microstructure and prevent the metal from work hardening. In this type of rolling hot rolled metals have very little directionality in the mechanical properties and ...

Tandem Rolling Process :: Total Materia Article

Tandem cold rolling mills can be basically split into two groups; sheet mills if they reduce hot band to sheet gauge or tin mills if they roll the same incoming material to tinplate stock. Key advantages of the tandem rolling process include cost reduction and good improvements in productivity especially when integrated with a continuous casting process. Rolling strip is widely used for ...
