Abstract: The process of plastic deformation of metal by passing it through the rolls called as the metal rolling. Rolling is widely used forming process, which can have high production figures and precise control of final product. Rolling is classified in two major parts the cold rolling and hot rolling. Every part has its own theory, development of rolling process and subsequently the designing of the cold rolling mill components, like rolls and rolling mill housing. The aim of the present paper is to understand the various methodologies which are used to design the cold rolling mill. We have focused on the history of the rolling process; it is understand that the rolling process was adopted since year 1590. Although it was raw method but it initiated the slitting rolling mill and the actual experimentation were started from year 1670. In those days rolling was concerned with rolling of bars only after few years the rolling of bars were started. We also tried to discuss the earlier patents which were granted in 18th century and was related to the tandem mill which were using copper and brass as the rolling materials. In year 1783, after the entry of grooved rolls the rolling production increased up to 15 times and that was the start of modern rolling mill. While reviewing the design of rolling mill components our area of interest is to visit design of rollers and rolling mill housing. We have discussed the different parameters and factors that affect the roll design. The calculations for the power required for rolling operation and the roll dimensions are also discussed. In reviewing the design of rolling mill housing, we try to explain the load that comes on the rolls during the rolling operations and how it affects the bearing life. The rolling mill housing designed optimisation has achieved by using different Finite Element Analysis techniques and various experimentation for rolling mill housing structural analysis is also reviewed.
