Metal Rolling

During a metal rolling operation, the geometric shape of the work is changed but its volume remains essentially the same The roll zone is the area over which the rolls act on the material, it is here that plastic deformation of the work ....

Rolling processes

e 6 T=05FL 511 The power required per roll can be estimated by assuming that (F) acts in the middle of the arc of contact; thus, in Fig (5-4), a = L/2 Therefore, the total power (for two rolls), in SI units, is...
