    摘要： A method of producing aluminum alloy sheet product includes casting a slab or ingot, homogenizing the cast slab, and hot rolling the homogenized slab to provide an intermediate gauge product. The temperature and other operating parameters of the hot rolling process are controlled so that the temperature of the ingot at the beginning of hot rolling is maintained at a temperature between 925° F. (496° C.) and 1025° F. (552° C.), and the temperature of the intermediate gauge product exiting the hot rolling step is between about 500° F. (260° C.) and 600° F. (316° C.). The intermediate gauge product is then subjected to a cold reduction of 45% to 70%, annealed, and cold rolled to final gauge. The combination of controlling the hot rolling to provide the desired hot line entry temperature and the desired exit temperature of the intermediate gauge product and annealing prior to cold rolling to final gauge minimizes or eliminates the appearance of ridging line defects in the aluminum sheet product when the product is subjected to further straining in a forming operation. An improved aluminum alloy sheet product is produced having a superior surface finish for use in automotive components while maintaining a higher strength than that of the prior art.

    摘要： A method and apparatus for making aluminum alloy sheet product with improved paintbake response during automotive paintbake cycles, resistance to natural aging and better formability includes rapidly heating the aluminum alloy sheet product between a solution heat treating/quenching operation and a sheet coiling operation. Performing the rapid heating at this stage in the sheet manufacture minimizes the adverse effect of early natural aging (dwell time) on the paintbake response of these types of aluminum sheet alloy products. According to the invention, this dwell time is minimized by the application of a rapid heating step immediately following quenching from the solution heat treatment. After the aluminum sheet product has been rapidly heated, it is immediately coiled and cools under ambient conditions in coil form, this ambient cooling providing a pre-aging treatment which contributes to the improved performance of the sheet product in paintbake response, improved formability and natural aging resistance.
