Method for rolling steel sections having flanges or flange-like portions

A method for rolling a steel section having flanges or flange-like portions from a steel bloom of rectangular cross section in a rolling mill comprising a series of roughing shaping rolling stands for roughing the bloom, a universal rolling mill stand having a pair of opposed horizontal rolls and a pair of opposed vertical rolls, and a series of finishing shaping rolling stands for finishing the shape rolled in the universal rolling mill, which method comprises:

• rolling the bloom in the roughing shaping rolling stands for roughing the bloom to a rough shape having a width greater than the shortest distance between the outer circumferences of the opposed vertical rolls in the universal rolling mill stand and having a reduced cross-section which is relatively flat as compared with the finished steel section, said rough shape portions to be shaped into flanges or flange-like portions in the finished steel section;
• rolling the thus obtained rough shape in the universal rolling mill stand for causing the pair of vertical rolls and the pair of horizontal rolls to carry out bending deformation mainly of the portions to be shaped into the flanges or flange-like portions;
• and finish rolling the thus deformed shape in the finishing shaping rolling stands for finishing the shape into the finished steel sections.
