Rolling method for the production of flat products (11 1) with low productivity, which comprises a continuous casting step at a speed comprised between 3.5 m/min and 6 m/min of a thin slab (1 1) with a thickness comprised between 25 and 50 mm. It also comprises a roughing step to reduce the thickness in at least one roughing stand (20, 20a, 20b) to a value comprised between 6 mm and 40 mm, and suitable for winding, a rapid heating step by means of induction in order to at least restore the temperature lost in the segment downstream of casting and in the roughing step, a winding/unwinding step in a winding/unwinding device (34) with two mandrels. The method also comprises a rolling step in a rolling unit that consists of a single reversing stand (22) of the Steckel type to roll the product unwound by the winding/unwinding device (34), which comprises at most five rolling passes, or four inversions, in order to obtain a final product with a thickness comprised between about 1.4 mm and 10 mm, preferably between about 1.4 mm and 8 mm, a cooling step and a step of winding the final product. |
