<p>Rolling stand with multiple rolls suported as cantilevers for hig-speed rolling, which comprises a motor unit (16-15) that actuates at least one common shaft (22a) which transmits motion to a plurality of pairs of rolls (11-12) with their axes placed alternately substantially at a right angle to each other (11a, 12a, 11b, 12b......11n, 12n), the stand including from six to ten pairs of rolls (11-12), the rolled stock being kept under traction between one pair of rolls (11-12) and the next pair (11-12), cooling chamber means (13) followed by temperature equalisation chamber means (14) being included between the pair of rolls (12) which processes round sections and the pair of rolls (11) which processes oval sections, the length of the cooling chamber means (13) being at least a function of the rolling speed of the pair of rolls (12) positioned upstream of that cooling chamber means (13), the cooling chamber means (13) being progressively longer in the direction of feed of the rolled stock.</p> |
