Rolling method for the production of flat products 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 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 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 with two mandrels. The method also comprises a rolling step in a rolling unit that consists of a single reversing stand of the Steckel type to roll the product unwound by the winding/unwinding device, 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. |
