During solidification the strand is cooled to a temperature above 700° C. and divided into thin slabs. The thin slabs then pass through an equalization furnace standing in line where they are reheated to a temperature ≦1170° C. and continuously rolled in a multi-stand hot rolling mill to give hot strip having a thickness of ≦3.0 mm. The first shaping pass is performed at a temperature in the rolling stock up to 1150° C. The reduction in thickness is at least 20%. The hot strip is cold rolled in one or more stages with recrystallizing intermediate annealing to a final thickness in the range of 0.15-0.50 mm.

摘要： The invention relates to the joining of flat products of metallic materials to be interconnected overlapping. The joining takes place in a roll nip into which the flat products to be interconnected are introduced at an acute angle. Before they are pressed on one another in the roll nip, they are heated on their facing surfaces by radiation energy, but not melted. By a suitable profiling of at least one roller generated surface or one flat product the surface pressing is limited to the zone of the overlap joint and any flow of material transversely of the direction of the overlap joint is prevented.
