Read OnRolling mill guides are to help the billet safely pass through the rolling mill, clear oxide scale of billet, and make the surface of billet smoother. Rolling mill guides play a main role in ensuring the surface quality of the rolled products.
Read OnAbstract –In hot rolling mill process the rollers is subjected to heating and cooling cycles with different processing parameter. This nature of heat and processing parameter found some cracks, wear and tear in hot roller. In this work, the study of existing process was done to find the root cause of the cracks in roller mills.
Read Onthe work roll of a rolling mill. The considered hot rolling mill consists of two hollow cylinders receiving heat in contact with the work piece and cooled by convection on its internal and external surfaces. Hsu et al. [19] considered a three dimensional inverse model for estimate the surface thermal behavior of the work Roll in hot rolling ...
