Abstract: | Results of a series of tests rolling beams in the first two passes, using lead as a model material, are presented; they include measurements of relative spread, natural elongation, roll load, roll torque and the observed changes in deformation modes with variation in shape factors (height to width ratios) of the specimens and the relative draughts.A comparison of these results is made with those obtained using empirical formulae suggested by earlier research workers. The observed rolling loads are compared also with measurements made of the die loads when rectangular specimens with the same shape factors as in these rolling tests were compressed between shaped dies having grooves similar to that in rolling and compressed under conditions of plane strain and in open-die compression. |
