Fundamental concept of metal rolling

Fundamental Concept Of Metal Rolling

The friction varies from point to point along the contact arc of the roll. However it is very difficult to measure this variation in , all theory of rolling are forced to assume a constant coefficient of friction . For cold-rolling with lubricants, 0.05 0.10. For hot-rolling , 0.2 up to sticky condition.

Rolling Of Hot Strip And Strip Defects Ispatguru

Jan 14, 2017 Elastic deformation of the mill takes place during rolling. Mill spring can be avoided, if stiffer rolls are used which means that the roll material is having high stiffness or elastic constant. Normally elastic constant for mills may range from 1 to 4 GNm-1. Roll elastic deformation can result into uneven strip thickness across.
