ABSTRACT:
System to roll at least two sections (13) in blocks of fast rolling mill stands, each fast rolling mill stand (11-12) including one pair of rolling rolls (17) supported as cantilevers and having alternately a horizontal axis (17o)/vertical axis (17v) or viceversa, the system comprising, in cooperation with the respective pairs of rolling rolls (17) of the block of fast rolling mill stands (11-12), a first guide box (15) for round sections which is positioned upstream of the first pair (11) of rolling rolls (17v), a second guide box (20) which receives oval sections and displaces at least partly at least two sections (13) from the rolling plane of the first pair of rolling rolls (17v) to a plane perpendicular to that rolling plane, a third guide box (24) with rolls which receives oval sections and aligns the same on the rolling plane of the second pair of rolling rolls (17o) and a fourth guide box (23) which receives round sections and displaces the sections (13) at least partly from the rolling plane of the second pair of rolling rolls (17o) to a plane perpendicular to that rolling plane, the fourth guide box (23) being followed by a fifth box which aligns the round sections on the rolling plane of the third pair of rolling rolls (17v), and so on in this sequence for the other pairs of rolling rolls (17v-17o), the second, third and fourth guide boxes (20-24-23) displacing the sections (13a-13b) without changing the circumferential position of the axes of the sections in relation to the horizontal.
