Future Research Potentials of Hot Rolling Process: A Review

Abstract

The hot rolling is a fundamental forming process in which the casted steel bars, bloom, and billets are converted into finished products. The setup cost of hot rolling is too high and at such adverse working condition, controlling the quality of product is essential. The rolled products are widely used in many sectors such as automobile, railways, naval architecture, and petroleum industry. The hot rolling of materials processed at high temperature and controlled environment. The mechanical properties like strength, ductility, hardness, thermal conductivity, and metallurgical properties like crystal structure and grain size influences the quality of rolled product. The inherent functionality of rolling process may lead to defect which causes the rejection of final product. It leads to monetary loss as well as waste. In this paper, the critical review of hot rolling has been done to find the future research potential. In this paper, an effort is made to study the research reported in literature on the innovations in hot rolling and find the future research potential.
