COMBINED CONTINUOUS CASTING AND METAL STRIP HOT-ROLLING PLANT

A combined continuous casting and endless rolling plant for a metal strip, comprising-a continuous casting line (1) for casting a slab;-a first rolling mill (6) for roughing the slab and for obtaining a transfer bar;-a second rolling mill (11) for finishing the transfer bar and for obtaining a strip;-a third rolling mill (18), comprising at least two rolling stands (17), for further reducing the N thickness of the strip;-accumulation means (20) of the strip comprising at least one first reel (37, 37′) dimensioned to wind and unwind a coil weighing from 80 to 250 metric tons and/or up to 6 meters in diameter, named mega coil;-first cutting means (13), arranged between said third rolling mill (18) and said accumulation means (20), configured to cut the strip after the mega coil has been wound on the at least one first reel (37, 37′);-at least one second reel (48) for winding portions of strip, unwound from said accumulation means (20), up to a predetermined weight limit or coil diameter limit;-second cutting means (47), arranged between said accumulation means (20) and said at least one second reel (48), adapted to cut the strip whenever a portion of strip wound on the at least one second reel (48) reaches said predetermined weight limit or coil diameter limit.
