Definitions

  • the invention relates to a rolling mill for producing a rolling stock, in particular a rolled strip, consisting of work rolls preferably arranged one above the other in a roll stand, which are optionally supported on support rolls or on support rolls and intermediate rolls, with strip deflectors, spraying devices arranged on the rolling mill on the inlet and outlet sides.
  • the object of the invention is to significantly improve the construction of a rolling mill equipped with belt deflectors, spraying devices, roller belt lifting devices, extension rails and roller belt guide tables, particularly with regard to the space requirement of these additional units.
  • the rolled strip lifting devices with strip deflectors, spraying devices, extension rails and rolled strip feed tables are combined to form a single unit and are arranged within the roll stand in the immediate vicinity of the roll gap of the work rolls.
  • the rolled strip lifting devices with strip deflectors and the spraying devices in Integrated work roll bending block which is provided with a recess into which the roll extension rails of the chocks arranged on the work rolls engage.
  • the assembly consisting of belt lifting devices with belt deflectors and spraying devices is connected to the work roll bending block so that it can move horizontally and vertically via grooves and feather keys.
  • the units can be very advantageously and optimally adapted at any time to the desired changes or to the changes that occur during operation of the rolling mill, in particular with regard to the roll gap width and the axial displacement of one work roll relative to the other.
  • a roll bending block designed as a work roll bending block, consisting of two parts and provided with a hydraulic adjusting device can also be used advantageously, as described and illustrated, for example, in European Patent Specification 0 059 417.
  • the grooves and feather keys connecting the structural unit to the work roll bending block are inclined with respect to the vertical arranged.
  • the length of the roller strip guide tables running in the plane of the rolled strip is designed to be changeable by means of mountable angle pieces.
  • the structural unit consisting of strip lifting devices with strip deflectors and spraying devices is formed in two parts. This very advantageously enables the use of this unit in rolling mills with work roll diameters of any size.
  • the rolling mill consists of two work rolls (2, 3), intermediate rolls (4, 5) and backup rolls (6, 7) arranged one above the other in a roll stand (1).
  • the rolled strip lifting devices (8) with strip deflectors (10), spraying devices (11), extension rails (12) and rolled strip guide tables (13) are combined according to the invention into a very compact, easily accessible structural unit and arranged within the rolling stand (1).
  • the rolled strip lifting devices (8) with strip deflectors (10) and spraying devices (11) are integrated in the roll bending block (15), which is very advantageously provided with recesses (16) into which the roll extension rails (12) on the work rolls (2, 3) engage chocks (17) on both sides.
  • the belt lifting devices (8) with belt deflectors (10) and spraying devices (11) form a rigid unit which can be moved horizontally and vertically by means of inclined grooves (18) and feather keys (19) in the area of the work rolls (2, 3) is held in the required position by the roller bending blocks (15) in cassette design.
  • the position of the multi-function block forming a rigid unit is a function of the position of the upper one and lower roll bending block (15).
  • the position of the roller bending blocks (15) - due to the type of cassette - in turn depends on the chocks (17) of the horizontal and vertical position of the work rolls (2, 3) in the roll stand (1).
  • this multi-function block shown in FIG. 1 and designed in accordance with the invention requires the use of work rolls which have only relatively small diameter differences (140-160 mm). However, if work rolls with larger roll diameter differences are to be used in a rolling mill, this can be easily accomplished by replacing the horizontal wear strips of the chocks (17) engaging the work rolls (2, 3).
  • the length of the strip conveyor tables (13) running in the plane of the strip can also be changed in length by mountable angle pieces (20).
  • the inventive design of the rolling mill also very advantageously allows the arrangement of rollers (21) for guiding and calming the rolling strip (22) and hydraulic adjustment devices (23) for the rollers (21), roller guide tables (13) etc. within the roll stand also in the vicinity of the roll gap (9).
  • the desired distance between the belt deflectors (10) and the bales or the surface of the work rolls (2, 3) is determined with the maximum roll diameter and closed roll gap (9) without rolling stock.
  • the distance between the roll bending block (15) arranged on the upper work roll (2) and the lower roll bending block (15) of the work roll (3) will also become correspondingly smaller in the rolling operation. Due to the inclination of the grooves (18) and feather keys (19), the multi-function block and thus the strip deflectors (10) are moved in the direction of the roll gap (9).
  • the groove (28) / feather key (29) remains at a certain inclination.
  • -Arrangements of the distance (30) between the surfaces of the work rolls (24, 25) and the belt deflectors (31) almost constant, ie the roll grinding is completely and automatically compensated.
  • the rolled strip (32) touches the lower work roll (25) and is guided optimally.
  • the distance (30) between the surfaces of the work rolls (24, 25) and the strip deflectors (31) is also influenced by the rolling stock located between the work rolls during operation of the rolling mill; however, this is of no importance, since the distance difference is negligible for thin strips of, for example, 0.2 mm, and for thick strips of, for example, 3 mm, the distance difference is still substantially below the strip thickness.
  • a thick strip thus runs without any problems, while in the case of a thin strip, the strip deflector (31) very advantageously ensures that the rolled strip (32) runs optimally.
  • the upper work roll (24) is moved upwards so that the beginning of the rolled strip does not butt against the lower work roll (25) or against the upper work roll (24) when it is introduced into the open roll gap (33).
  • the strip deflectors (31) of the rolled strip lifting device (34) make a relative movement in the vertical direction upwards, and due to the inclined groove (28) / feather key (29) connection they move away from the work rolls (24, 25) in the horizontal direction .
  • the belt deflectors (31) can be moved just below to the level of the bale of the work roll.
  • Figure 3 shows a rolling mill in which the upper work roll (35) has a significantly smaller diameter than the lower work roll (36). It represents an extreme combination in which the respective upper belt deflector (38) is at a greater distance from the work roll (35) compared to the lower belt deflector (38).
  • An optimal adaptation of the strip deflectors (38) arranged on the rolled strip lifting device (37) to these differently sized work rolls (35, 36) can also can be achieved very advantageously by adjusting the feather key, changing the wear strip or by dividing or separating the roller belt lifting device (37) into an upper part (39) and a lower part (40).
  • the work rolls (41, 42) are in the roll changing position. In this position, the work rolls (41, 42) are spaced as far apart from each other as possible, and the multi-function block (43) is in the farthest horizontal position from the work rolls (41, 42). In this position, the multi-function blocks (43) arranged on both sides of the work rolls (41, 42) form continuous rail tracks (44) for the chocks (45).
  • a spray unit as the spray device (11), which according to FIG. 5 consists of a compressed air-controlled, spring-loaded nozzle valve (46).
  • nozzle valve (46) air is preferably led axially into the nozzle body (48) under pressure in the direction of the arrow (47) under pressure in order to close the valve, the liquid (for example water) in a depressurized position through a supply line under pressure introduced the annular space (49) and from there through the openings (50) in the nozzle body (48) into the nozzle outlet opening (51) and in finely divided form on the respective Roll of the rolling mill hits.
  • the very stable multi-function block according to the invention makes it possible to release the band deflectors at a distance from the nozzles to the width of the nozzle, so that the resulting nozzles, including piloted nozzles, can be arranged which spray directly into the roll gap.
  • the height of the multi-function block also very advantageously allows the arrangement of several additional rows of these nozzles shown in FIG. 5.
  • the measures according to the invention are not limited to the exemplary embodiments shown in the drawing figures.
  • the multi-function block can be shaped in any way.
  • the respective structural design is left to the person skilled in the art in adaptation to the special use of the device.
