摘要

Production of metallic strips comprises cold rolling and annealing a metallic composite material consisting of a support layer (9) made from a first metal material and a metallic covering layer (10, 11) formed on the support layer. Annealing comprises a first annealing treatment in which the support layer is brought to the annealing temperature, and a second annealing treatment in which the penetration depth, via which the composite material is brought to the annealing temperature, is limited to a depth of the covering layer. Preferred Features: Annealing is carried out before cold rolling. Cold rolling is carried out in several stages with annealing carried out between the cold rolling stages.
