Abstract

The DI (Drawn and Ironed) canmaking properties (the effect of the load of DI canmaking, the dome inversion pressure and the load of neck forming) was measured in the 350ml 211 (66mm) diameter size DI canmaking with many kinds of steels prepared in the laboratory. The chemical composition, especially carbon content, was widely varied from 0.05 to 0.0010wt%. The following points were clarified. 1) The DR (double-cold-reduced) ultra-low carbon steel tinplate is advantageous for preventing the wrinkles at the necking by reducing the strength of the expected necking part. 2) The bottom reverse pressure depends on both thickness and YS of the tinplate. The pressure increment is evaluated experimentally to be 0.074MPa/0.02mm in thickness and 1.7MPa/10MPa in YS, respectively. As the results, the application of the-ultra-low carbon steel, adequately hardened by the cold reducing after annealing, may be advantageous for reducing tinplate thickness without deterioration of necking formability.
