Abstract

The continuously annealed tinplate with low carbon chemistry often exhibits the "fluting" trouble which is associated with stretcher strain defect, when it is roll-formed for making a 3-pieces can body. For preventing the occurrence of fluting, the influence of the forming conditions is focused in this study, leading to following results. The "flexor treatment" just prior to roll forming, recognized as effective for solving the problem, is attributable to the reduction of both the yield point elongation and yield strength in the tinplate. Furthermore, the tendency of the fluting occurrence can be drastically decreased by employing high speed or low temperature roll-forming condition. A greater number of stretcher strain pattern on the deformed sheet is introduced by the high speed or low temperature deformation. This, in turn, suppresses clear recognition of the stretcher strain pattern preferably.
