摘要： The invention relates to a method for manufacturing components from critical cold forming of light metal strip, preferably naturally hard Al alloys of the AlMg or AlMg—Mn types, in which the desired component is manufactured from the strip by at least one cold forming step and the plasticity is improved before the cold forming by means of a soft annealing. According to the invention, it is proposed that the region of the longitudinal edges of the cold-slit strips is heated in a depth in the strip width of at least 1 mm to a maximum of 10 mm in such a way that a temperature of over 150° C. is reached over a time span of more than 0.1 seconds to a maximum of 10 seconds.

摘要翻译： 本发明涉及一种用于制造轻金属带，优选AlMg或AlMg-Mn类型的天然硬质Al合金的临界冷成型的部件的方法，其中通过至少一个冷成型步骤从带材制造所需部件， 在通过软退火进行冷成型之前，可塑性得到改善。 根据本发明，提出将冷缝条的纵向边缘的区域以条带宽度的至少1mm至最大10mm的深度加热，使得过度的温度 在超过0.1秒的时间跨度达到最大10秒的150℃。

摘要： A method and system solution heat treat, at an elevated first temperature, a coil of aluminum alloy sheet to form a heat-treated coil and while at least a portion of the heat-treated coil is being solution heat treated, uncoil a heat-treated portion of the aluminum alloy sheet from the heat-treated coil and continuously quenching the uncoiled heat-treated portion to form a quenched sheet.
