    The roll is seated in radial bearing (2) which is fitted in adapter element (3). The adapter element is slidable on roll stand (4). A separate axial bearing (5) is fitted in housing (6) by bearing cover (7). The cover has an extension in form of a piston rod (7a) which carries a ring piston (7b) which operates in double-acting hydraulic cylinder (8) arranged concentrically to the roll (1). The cylinder is fitted on two journals (9) allowing slight swivelling movement to take up deflection of the roll. For detecting the actual value position emitter (13) is fitted on the roll stand (4) facing the front surface of the rolls with movable element (14) in contact with side bar fixed on the bearing cover (3a).

    The invention relates to metallurgy and relates to devices for the axial installation of mill rolls for the production of sectional steel.
    The installation and maintenance of a certain relative axial position of the interacting rolls, taking into account the axial forces occurring in the roll gauge, especially when rolling asymmetrical profiles, is important for rolling accuracy and direct yield of the rolled material. This also applies to the horizontal rolls of the universal rolling stand, since, due to the possible relative axial shear between the horizontal rolls, this can have a negative effect on the tolerances of the thickness of the profile elements. However, for example, when rolling profiles of sheet piling walls in the rolling stand of a rolling mill, it is necessary to withstand thickness tolerances.
    No longer speaks of the axial adjusting devices with manual control, also the installation mechanisms with electric drive are known. However, the known installation devices capture a roll cushion in which the roll is axially fixed, or the roll itself, which is then axially movable in the roll cushion, not axially moving. The installation mechanism can also capture a separate bearing or bearing housing. A disadvantage of the known axial roll alignment devices is that they can operate only between passes through the rolls. The axial forces generated in the roll gauge change during the rolling process, and since the installation mechanisms must ultimately rest on the rolling stand stand, it is impossible to avoid the relative shift in the roll gauge due to the elastic deformation of the roll itself, as well as means of permutation. Especially with an open calibration, the rolled material has an adverse effect. When rolling asymmetrical profiles with relatively high axial forces in the rolls, this disadvantage is taken into account, whereas the upper and lower rolls are fixed to one another by means of support shoulders. Friction on the support shoulders leads to higher costs for energy and rolls. In the field of rolling, devices for axial shear rolls are known, including double-acting hydraulic cylinders which can be driven during rolling. Such hydraulic axial mounting devices experience large elastic deformations at high metal forces on the rolls, which should be avoided when rolled.
    The invention is based on the task of providing a rigid fixation of the relative axial position of the rolls for the production of the profile steel in a different way than with the support shoulder on the sides of the rolls, at the same time improving the accuracy of the manufacture of rolled metal due to the backlash-free connection of the installation tool with the roller.
    Figure 5 shows the proposed device, a horizontal section through the bearing support on the service side.
    Roll 1 rests on a radial bearing, 2 which is mounted in cushion 3. Cushion 3 is installed with the possibility of axial shear in the window of bed 4 of the rolling stand. A separate thrust bearing 5 is clamped in the housing 6 by means of a removable
    5 of the cover 7, with which the rod 8, concentric to the roller 1, which carries the annular piston 9 is made in one piece. Relative here is the double-acting hydraulic cylinder 10 thus installed
    0 concentric to roll 1 and closed with two cylinder covers 11. The cylinder 10 has two diametrical, horizontally rotatable trunnions 12, through which it is pivotally supported.
    5 to two holders 13 in order to perceive the deflections of the roll 1. Retaining strips 14 are removably attached to the bed of the rolling stand, which serve to support pairs of wedges 15 through which the holders 130, i.e. spontaneously attracted to the frame of the rolling stand.
    For axial removal of the roll 1 together with the bearing support and the hydraulic cylinder 11, release a pair of wedges 15 and remove the retaining strips 14.
    To register the actual displacement values, the position sensor 16 is used, which is fixed on the surface of the bed 4 of the rolling stand facing
    0 a set of rolls, and the movable measurement element 17 of which, through the bar 18, is connected to the bearing cap 91 in the cushion 3. The actual movement values are recorded in this way in
    5 close to one end of the roll 1, so that all the deformations, including the compressibility of the working fluid to the left of the bearing cover 19, to the backlash-free support of the holders 13 on the base 4 of the rolling stand and on the retaining strips
    14 are taken into account when entering into an electronic position controller (not shown).
    During the deflection of the roll 1 under the action of the rolling force, the cylinder body 9 rotates on the trunnions 12, maintaining rigid contact with the support.
