Abstract (en)

[origin: EP0329999A2] When rolling I-section beams, control should be exercised over the thickness of webs and flanges. For this purpose, it is proposed to allocate to each roll of the universal rolling mill stand a gauge-meter circuit. In order to maintain a certain ratio of web elongation to flange elongation, it is furthermore proposed to couple the gauge-meter circuits together in an adjustable manner. Adjustment should be carried out as a function of the rolling program.
