Cold rolling takes the hot rolled product and processes it further. After hot rolling, the steel is cooled to room temperature, then passed through cold rollers at a temperature lower than its recrystallisation temperature. This rolling process is called annealing and relieves stress and leads to a higher yield strength and greater hardness.

Analysing metal working processes. G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 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.

The new X6h mill has better stiffness characteristics than the other two types of mills. Furthermore, the structure of the X6h rolling mill could be optimized based on an optimization theory, and on the basis of satisfying the requirements of stiffness and stress. The lightest roll system structure is recommended to design a good rolling mill.

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 cold rolling of metal strip is one process in which a sequence of processes is performed to convert the raw materials into a finished product. It is a deformation process in which the thickness of the strip is reduced by compressive forces exerted by two opposing rolls (normally in a fourhigh arrangement).

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, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
