Steel strips but also aluminum alloy strips are heated for this purpose using tempering and / or cooled very quickly. However, the temperature ranges in which steel strips and aluminum alloy strips are heated during heat treatments differ significantly. The heating of steel strips to achieve recrystallization is in the range of 950 ° C and more, whereas aluminum alloy tapes recrystallize already at temperatures around 300 ° C. For some aluminum alloys but must, for example, for later
- Precipitation hardening alloying elements are brought into solution, with temperatures around 580 ° C must be achieved. In order to subsequently maintain the alloying elements in a supersaturated state in the matrix, a rapid quenching of this temperature is required. Often, high heating and cooling rates for other metallurgical reasons are necessary [eg for grain refining]. Due to the need for high heating or cooling speeds such heat treatments can not be performed on the wound coil, but must take place in a continuous stream in so-called continuous furnaces and cooling sections. The rapid heating or cooling causes thermal stresses, which in particular with thin strips lead to distortions, which hinder both a stable tape running in the running process and can cause flatness defects in the finished product.
