a basic understanding of the mechanics of rolling mill rolls

  • Rolling processesAl-Mustansiriya University

    Rolling processes 5-1 introduction Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working called hot rolling owing to the large amount of deformation required.

    A Closer Look at Machine Styles. Three-roll initial-pinch (see Figure 5) or single initial-pinch plate rolls generally are for light-capacity applications and may be electromechanical or hydraulic. They work by pinching the flat sheet between two vertically opposed rolls while the third offset roll—or bending roll—moves upward to contact and then bend the sheet.

    The die is driven by a motor and the rolls turn only as feed between rolls and die develops friction. To make dry feed particles pliable for close compression and to decrease friction and absorb mechanical heat water is often added to the feed either as the formula is mixed or in the conditioning chamber of the pellet mill.

  • Failure analysis of work rolls of a thin hot strip mill

    In hot rolling mills premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the wear resistance and extend the service life of rolls.
