ABSTRACT:
Process and apparatus for preventing defects in the symmetry of rolled H-beams or I-beams, i.e., a faulty position of their webs (4) in relation to their flanges (5), by correcting such defects in situ. The differential between the torques applied to the upper and lower rolls (1,2) of the rolling stand is determined and compared to a predetermined threshhold value (.delta.). Any excess of the measured value over the threshhold value is eliminated by correction of the elevation of the inlet table of the rolling stand so as to reduce the measured value to below the threshhold value.
