    3 placement placement, cross section; in fig. 7 the same, for a variety of different profiles, some of which have a different wall height, but the same height of the shelves, a section; in fig. 8 the same, for a variety of different profiles with a combination of two gauge rolls on one pair; in fig. 9 - the same, for a variety of different profiles on each side, having two stepped groups of streams. With the known rolling process (Fig. 1), the workpiece 1 is rolled by successive passes in one (or more) universal stands containing two horizontal rolls 2 and 3 and two vertical wipes 4 and 5, as well as one or more cages containing two horizontal rolls 6 and 7, followed by the completion of the process in the universal finishing stand (not shown). During the passes (Fig. 1), the horizontal rolls 2 and 3 exert direct pressure on the wall 8 and the side edges 9 and 10 of the flanges, while the vertical rolls 4 and 5 exert direct pressure on the surface of the flanges 11 and 12. During the passages in order to reduce The juice edges 9 and 1O of the flanges (Fig. 2) horizontal rolls 6 and 7 do not directly apply the internal and external surfaces of the flanges. Not 12, as well as the wall 8 of the profile, but they have a pressure on the side edges 9 and 10 of the flanges 11 and 12. The letter L, denotes the length of the roll barrel vd axis axis 13. The profile (Fig. 2) is a beam with a wall height a (for a given passage) and a total height h (also for a given passage). In the following, the terms wall height and flag height are used to designate the heights for the passage under consideration, these heights may vary between the passages in the same creek. The vertical plane of the longitudinal symmetry of the can and the vertical plane of symmetry of the gauge are the same and are shown by line 14. The surfaces 15 and 16 of the grooves, which are located respectively on the rolls 6 and 7, play the role of guides. The surfaces 17-20 of the streams are designed to affect rolling, respectively, on the edges 9 and 1O of the flanges 11 and 12. FIG. Figure 3 shows an example of the invention with a plurality of streams on the swaths in a two-seven roll stand. The proposed kathabr can be used in a three-roll stand, and in any other. Brooks are shown only for two beams 21 and 22, markedly differing in the height of the walls hell and a, the heights of the flanges can be different (Fig. 3) or are equal. The vertical planes of symmetry of both beams are merged and indicated by line 14. On rolls 6 and 7 of bottom 23–26 of streams, designed to compress the edges of flanges of beam PQ, are separated from bottom 27–30 of other streams by shoulders 31–34, and bottom 27–30 are intended for Crimping flange flanges of the beam R. Burt 31-34 must have an appropriate thickness of the short-circuit conditions of their strength, although they do not exert any pressure and serve mainly to guide the profiles. Brooks of more than two different profiles may be intended for placement on the same pair of rolls, provided that the profiles are chosen reasonably and the said rolls are used only for the maximum possible length of the barrel in the cage. Parts of the PC caliber (Figs. 3 and 4), covering the walls of the beams P and P., are not available. A rolling force load, and it is these that are common to all streams. Profiles can have the same configuration, but different sizes (fig. 3) or .feTb different configuration as in fig. 4, where rolls 35 and 36 are shown, on which there are beam gauges P with wall height ap and gauge rail R with wall height a. The vertical axial planes of both different calibers in this case are merged and shown by line 14, but they may not merge. When the heights of the walls of several different profiles are such that placing the streams on the same pair of rolls does not allow for an appropriate thickness of the shoulders, it is possible in one of the embodiments of the invention to offset one or more of these shoulders and to obtain a stepped bottom of the streams, t . another form of distribution of streams (Fig. 5). FIG. 5 also shows the streams of the three beams P, P., P, respectively, with the high ap, a, a2 walls and various, -hj. flanges, forming heights K-and-38. Vertical rolls 37 of the plane of symmetry of all the beams in this case merge, as this is preferable.
    Within the scope of the invention, combinations of the above examples may be carried out, such as shown in FIG. 6, where the rolls 39 and 40 are made with a combination of stepped streams of two beams PO and P and, built-in caliber rail R.
    For the purpose of applying the invention without additional costs or substantially modifying the operation of the rolling mill on which it is used, the preferred embodiments of the invention are described for cases where the vertical planes and longitudinal symmetry of all individual profiles merge. - This single longitudinal plane of symmetry of all calibres merges with the rolling axis when cages are located one after another.
    The variant shown in FIGS. 6 is also applicable to profiles in video beams P, P and P with different lengths a ,, a, aj and different heights - bd, 4, flanges. The very small differences in the length of the walls of the two adjacent beams, starting from the shortest wall, dictate the expediency of the stepwise alignment of the streams (flash 5).
    Within the scope of the invention, it is also possible to combine combinations of streams with a stepped arrangement, separated by butts, as in FIG. 3-6.
    Imagine a combination of the beams P, P P ,,, P, RL, having respectively increasing lengths a, a, Qn, a, a, and from the walls but with the same height of the flanges in relation to two to two. Assume, that the beams PQ and РЗ have the same height b of the flange, beams Р and Р - the same height ti of the flange, beams Р2 s the same height of the flange -h. Suppose also that the length a "of the wall of the RE beam is correspondingly longer than the length and of the wall of the beam P2 in order to make it possible to place the separation flange 41 between the first group of stepped streams and the second group of streams to crimp the flanges of the RE, P and JPg beams. In this combination (Fig. 7), the rolls 42 and 43 have the first group of stepped streams (Fig. 5) to compress the beams PO, P and P2, as well as another group of streams separated from the previous streams by means of a collar 41, which allows compressing flanges of the beams P, P, and PC. The caliber portion serving as the shortest web is common to all embedded streams.
    In the embodiment of the invention (FIG. 8), it is possible to have rolling mill 1, rollers 44 and 45 calibers for the beams PO, P, P, PZ, P. PS and beams Pj, P7 and P0. The creek groups in FIG. 8 can be used to obtain the required wall heights and by changing or maintaining the center distance E of the shaft (ows - to obtain the corresponding flange heights.
    In the embodiment of the invention (Fig. 9), it is possible to arrange along the length of the barrel L, the rolls 46 and 47 more and different combinations of strands for beams with different or equal heights and walls. If, on the one hand, extreme streams are combined, and on the other hand, middle streams are combined, then two groups of unequal beams are obtained. If extreme streams are combined with medium ones, then two groups of equal high beams are obtained.
    In the embodiment of the invention shown by the dotted line on the right side, FIG. 8, it is possible to use a section of a common jumper of gauge Pd, P, P beams for the purpose of making there one or more open streams for profiles 48, such as square, rhombus, round, rail pads, paired rods, etc.
    In addition, the device may contain other combinations of individual groups of streams, when the length of the roll barrel allows.
