摘要：

Effects of DI (Drawn and Ironed) can base profile on can bottom performance such as dome reversal pressure, bottom growth and axial buckling load are experimentally investigated. The material used is 0.18 mm thick steel with tensile strength inthe rolling direction of 466 MPa. The factors studied in the base profile are base diameter, rim radius, dome shoulder radius, dome radius and dome depth. The dome reversal pressure is improved with decreased base diameter or increased dome depth. Bottomgrowth is improved by decreasing the rim radius, but a smaller rim radius means a thinner of rim inside wall, which in turn leads to the decrease of the dome reversal pressure, particularly for a large dome depth. Due to the fact that the rim inside wallmoves toward the rim radius with bottom growth, the rim inside wall is a very important factor. A good correlation between the dome reversal pressure and the rim inside wall length is obtained.
