TAILIEUCHUNG - Rolling of metals Subjects of interest

This chapter provides information on different types of metal rolling processes which can also be divided in to hot and cold rolling process. • Mathematical approaches are introduced for the understanding of load calculation in rolling processes. • Finally identification of defects occurring during and its solutions are included. | Chapter 3 Rolling of metals Subjects of interest Introduction objectives Rolling mills Classification of rolling processes Hot rolling Cold rolling Forces and geometry relationships in rolling Simplified analysis of rolling load Rolling variables Problems and defects in rolled products Rolling-mill control Theories of cold rolling Theories of hot rolling Torque and power Tapany Udomphol Jan-Mar 2007 Suranaree University of Technology Objectives This chapter provides information on different types of metal rolling processes which can also be divided in to hot and cold rolling process.

Suranaree University of Technology Tapany Udomphol Jan-Mar 2007 Ingot Rolls Plate Sheet or Foil f Introduction- Definition of rolling process Note rolling processes can be mainly divided into 1 hot rolling and 2 cold rolling. Definition of Rolling The process Rolling process The metal is subjected to high compressive stresses as a result of the friction between the rolls and the metal surface. of plastically deforming metal by passing it between rolls. Rolling is the most widely used forming process which provides high production and close control of final product. Suranaree University of Technology Tapany Udomphol Jan-Mar .
