ABSTRACT:
A rough beam (4) is formed on a universal stand (11), and a two high stand starting with an initial section (1) of rectangular or trapezoidal cross-section, in two series of passes in the universal stand. During the first series reduction of the web forming portion is effected by horizontal rolls (5, 6) acting on the central portion of the initial section (1) and during the second series of passes both the horizontal rolls (5, 6) and the vertical rolls (7, 8) of the universal stand (11) simultaneously reduce the web and flanges, respectively. The rough-beam being formed during the second series of passes is also rolled in the open grooves of a two high stand.
