Method to roll strip and plate and rolling line which performs such method

Rolling line to roll strip and plate starting from thin slabs produced by continuous casting, which comprises in sequence:

• at least one continuous casting machine, shears for shearing the strip or plate to obtain segments of a predetermined length, a heating furnace system, a second descaling unit, a roughing rolling mill stand, a tunnel furnace, a third descaling unit and a finishing train and a cooling zone, the line being characterised in that the continuous casting machine comprises two casting lines fed by a ladle system cooperating with a mould system, each casting line comprising the shears, a first rotary descaling unit downstream of the shears, and the heating furnace system, the heating furnace system being structured with modules, each of the modules having a length at least equal to a length of the segments, at least a last downstream module being transversely movable between at least two positions, one of the two positions being on the same axis as the roughing rolling mill stand and the finishing train.
