Estimating the term…
The invention relates to a method for producing a strip made of an AlMgSi alloy, in which a rolling ingot made of an AlMgSi alloy is cast, the rolling ingot is subjected to homogenization, the rolling ingot having been brought to rolling temperature is hot-rolled and is optionally cold-rolled to the final thickness thereafter. The problem of providing an improved method for producing aluminum strip made of an AlMgSi alloy, with which AlMgSi strips having very good shaping behaviour can be produced reliably, is solved in that immediately after exit from the final rolling pass, the hot strip has a temperature of between more than 130° C., preferably 135° C., and at most 250° C., preferably at most 230° C., and the hot strip is wound up at this temperature.
A method for manufacturing a strip from an AlMgSi alloy, comprising casting a rolling ingot from an AlMgSi alloy, wherein the rolling ingot undergoes homogenization, the rolling ingot which has been brought to a rolling temperature is hot rolled then optionally cold rolled to final thickness, and the finished rolled strip is solution annealed and quenched, wherein immediately after being discharged from the last hot rolling pass, the hot strip is at a temperature of more than 130° C. to 250° C., preferably to 230° C., and the hot strip is coiled at this temperature.
