PRODUCTIVITY AND QUALITY IMPROVEMENT THROUGH SETTING PARAMETER IN HOT ROLLING MILL-A REVIEW

Rolling is a forming operation where plastic deformation of a work piece is achieved by compressing it under application of force between two rotating rolls in the mill. The present paper aims at studying parameters which affects the quality of products in hot rolling mill and optimizing one of them. Generally, it is seen that most of the rolling mills work on the principle of experience and mutual settlements. There are no fixed, live and calculated arrangements of process or processes. However, rolling mills are one of the most productive and sensitive areas of industry where slow process or any breakdown in production line is not acceptable, even if the company have to go for costly machines or any costly environment. But in order to have higher production various parameters are considered which directly or indirectly (both quantitative and qualitative aspects of the process) contribute to increase in productivity.
