Rolling mill rolls and roll bearings base are the core parts of the whole working stand of the rolling mill, and the roll is the main part of the direct rolling mill. In the process of rolling, the roll contacts with the workpiece directly, forcing the plastic change of the workpiece. At the same time, the roll bears a huge rolling pressure, and the stress changes with time due to the …
The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its cross-sectional area.. The types of rolls used in rolling …

2. Rolling Mill classification Rolling mill is used to reduce successively the thickness of the metal strip as per the requirement. Hot rolling mills are used for mass thickness reduction at high temperatures, whereas the cold rolling mills are used as secondary rolling operations to attain more precise dimensional and mechanical properties.
The roll designer should take the following into consideration: Maximum roll length is limited. The forming pressure of the ends of the rolls may bend the shafts. While produce wider profile, the mill should be equipped with supports between roll forming stands. The minimum length of the shortest profile should not be less than twice the roll ...
A Simulink and mathematical models have been proposed in this study in order to control the thickness in a rolling mill process. The simulation results show that the thickness oscillation can be manipulated with high accuracy by using NARMA-L2, since it can remove the non-linearity of servo system and other disturbances complexities. The proposed NARMA-L2 …
