    A process for forming a rail blank in a universal stand, starting with an initial section (1) of rectangular cross-section comprising a first series of passes for cutting into the web forming portion by way of horizontal rolls (2, 3) accompanied by reduction of the head by way of one of the vertical roll (5), and a second series of passes for simultaneously reducing the head flank forming portions by the horizontal rolls (2, 3) and the base forming portions by one of the vertical roll (4) of the universal stand, the other roll (5) remaining non-active.

    2, the method according to claim 1, wherein tl and h and y and the fact that simultaneously with the formation of the neck with the crests of the horizontal rolls cut the sole profile with the ridge of the vertical roll and roll the sole with the vertical roll with a more gentle ridge and a smooth barrel profile.
    The invention relates to rolling production and can be used to obtain a shaped billet of a rail profile on a mill having in its composition a two-roll WG universal stands.
    The aim of the invention is to intensify the rolling process by reducing the number of passes.
    FIG. Figure 1 shows the deformation of a rectangular blank in the first stage of formation 5 in Fig. 2 — a reduction in the cross section of the blank during the first (I) and second (l) formation stages | in fig. 3-5 shows the configuration of vertical rolls for cutting the rail foot; Figs 6 and 7 show the cutting and rolling of the rail foot during the first and second stages of formation; in fig. 8 - rolling of a shaped blank in a double; an alkaline stand; in fig. 9 is a diagram of the formation and position of the profile of the finished billet in the original rectangular billet; in fig. 10-13 are variants of the composition of the mill equipment for implementing the method.
    The method is implemented as follows.
    The workpiece 1 enters the universal stand with horizontal 2 and 3 and vertical A and 5 rollers.
    Horizontal rollers are provided with ridges 6 and 7 of a larger diameter for cutting the billet and forming a neck at both stages of forming the billet and sections 8 and 9 for deforming the lateral surfaces of the rail head at the second stage of formation.
    The preform is formed in two stages. In the first stage of formation, in the unierce caliber
    3. The method according to claim 15, wherein the first and second stages of the formation of the blank are carried out by the same pair of horizontal rolls with a stepped barrel configuration.

    the ridges of the horizontal rolls compress the neck of the workpiece (1W) and at the same time carry out the entire height-HiTo deformations of the head (1g) by one of
     vertical rolls and, to a lesser extent, 5 soles (In) with another roll.
    The vertical rolls at this stage of the formation are used mainly for d-centering the roll.
     During the second stage of formation in the universal caliber, the neck compression (Pn) is continued and the rail head is deformed on the lateral surfaces (Pg), at the same time carried out by a vertical roller and the vertical deformation of the rail bottom (Pp), at which stage the alternation of compression in the universal caliber was performed with swaged in a two-roll gauge formed by rolls 6 and 7
    In the case of rolling a rail size with a large width of the sole, the method of cutting and subsequent rolling of the sole is used by a vertical roller 4j, which for this purpose is performed with ridges of various flatness Ш and 11. and smooth 12. To save the park of rolls, the first and second stages of formation can be carried out using the same horizontal rolls of the same horizontal rolls with a stepped barrel configuration. 11, the proposed method permits the rolling of shaped; blanks with; -. Minimum number of passes.
    For the implementation of the method, a mill can be used, including universal and two-roll stands in different variants (Fig. 8-11) in terms of the number and sequence of arrangement of these stands.

    1. METHOD OF ROLLING OF SHAPED BAR FOR THE RAIL PROFILE from a rectangular billet, including the formation of the neck by the crests of horizontal rolls and sections of the head and sole by horizontal rolls of universal calibers when alternating with the compression of these sections in double roll calibers, characterized in that, in order to intensify the rolling process by reducing the number of passes, at the first stage of formation, the workpiece is crimped in a universal gauge with ridges of profiled horizontal rolls on the neck section and one temporarily carried vysotnuyudeformatsiyu head one of the vertical rolls, and a second step of forming a universal caliber continued compression neck and side surfaces of a head g horizontal rolls and simultaneous · but carried altitude deformation soles other vertical roll, producing in this stage alternation with a reduction in a two-roll calibers.
