  • A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING …

    As regards "abnormal" rolling conditions - which are more or less very "normal" for rolling mills - roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll failure have to be discussed and determined (or vice versa) to reduce the risk of repeated roll …
