    摘要： Disclosed is an Al—Mg—Si aluminum alloy sheet that can prevent ridging marks during press forming and has good reproducibility even with stricter fabricating conditions. In an Al—Mg—Si aluminum alloy sheet of a specific composition, hot rolling is performed on the basis of a set relationship between the rolling start temperature Ts and the rolling finish temperature Tf° C., whereby the relationship of the cube orientation distribution profile in the horizontal direction of the sheet with the cube orientation alone or another crystal orientation distribution profile at various locations in the depth direction of the sheet is made more uniform, suppressing the appearance of ridging marks that develop during sheet press forming.

    摘要： A metal mold is disposed adjacent to the outer circumference of a base ring, and has a molding face in the inner circumference and a plurality of grooves for forming beads on the molding face along the circumferential direction. A coil for electromagnetic forming is disposed adjacent to the inner circumference of the base ring. When a momentary large current is applied to the coil in this arrangement, the diameter of the base ring is expanded by pressing the base ring toward the molding face of the metal mold such that the base ring is molded into a shape corresponding to the molding face by electromagnetic forming. Improvements such as a metal mold capable of degassing, a separable metal mold, roll-correcting after electromagnetic forming, application of momentary large current over several times, a metal mold with a cutting blade, use of a base ring with a large number of holes, and a metal mold with positioning means are then added. With these improvements, a highly accurate cylindrical ring with beads can be produced at low cost and with high productivity.
