<p>A rolling line (10) for the production of flat products (111) comprises a casting machine (12) suitable to continuously cast a thin slab (11), a temperature maintenance and homogenization unit (18), a rolling unit (22) comprising at least a double rolling stand (23a, 23b) of the Steckel reversing type downstream of the temperature maintenance and homogenization unit (18), at least a forming stand or roughing stand (20), directly connected immediately to the exit of the casting machine (12) and upstream of the temperature maintenance and homogenization unit (18), and suitable to reduce the thickness of the slab (11) just solidified. The forming stand or roughing stand (20) is configured to perform an adaptive reduction of the thickness of the cast slab (11) smaller than or equal to about 65% at least as a function of the thickness, width and type of material of the finished flat product. The rolling unit (22) is configured to perform a reduction of the reduction of the thin slab (11) coming from the temperature maintenance and homogenization unit (18) to a thickness comprised between about 1.2 mm and about 20 mm by means of at most three double rolling passes through the double rolling stand (23a, 23b).</p> |
