Abstract (en)

[origin: WO9000100A1] The invention concerns a process and an installation for manufacturing a metal strip with a fine-grained or uniform structure and having a thickness less than or equal to 10 mm. Immediately after casting, the strip undergoes a second treatment, namely adjustment of the treatment temperature and plastic deformation of the strip, virtually without any reduction in thickness, and possible subsequent annealing and cooling in function of the nature of the strip material. This continuous production of a metal strip which has the desired final dimensions and contains no structure undesirable for subsequent use is obtained by simple means and without expensive rolling.
