A BASIC UNDERSTANDING OF THE MECHANICS OF

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...

rolling defects of after machined metals

The rolled parts are more thicker than the required thickness of metal because of the rolls get deflected by high rolling forces apply The Elastic deformation of mill takes place on the metalSo some of rolling defects are provided in the metal forming...

Roll Cooling Lechler

In the metalworking rolling process in hot and cold rolling mills heat is generated by friction and deformation in the mechanical forming of the rolling stock As a result efficient cooling of the rolls as well as the surrounding roll area is essential for the forming process in order to ensure stable roll temperatures and effective heat...
