Definitions

  • the invention relates to a method for operating a steel bar mill and a bar steel mill to carry out the method, which comprises rolling stands arranged on a rolling line, which are combined into a preliminary season, at least one intermediate season and a finishing season, the finishing season being a cooling section arranged on the rolling line for thermo mechanical finishing rolls is immediately upstream.
  • Thermo-mechanical finish rolling is understood to mean the cooling of the rolling stock for all occurring cross-sections to a comparatively low rolling temperature of approx. 750 degrees Celsius, in order to always finish rolling under the same rolling temperature, regardless of the size of the rolling stock, in order to obtain a structure that is favorable for further processing and that To suppress scale formation (DE 24 37 684 C2 and EP 0264 868 A2).
  • the invention has for its object to eliminate the need for constant adaptation of the finishing stack for each finished cross-section to be rolled of a steel bar mill and still be able to perform the finishing stitch or passes behind the cooling section.
  • an intermediate season according to the invention consists of the same stand groups, each with a pair of vertical and horizontal rolls, the stand groups with their drives including drive motor being one structural unit form, and wherein all scaffolding groups to be implemented are suitably prepared for operation in the scaffolding behind the cooling section.
  • all scaffolding groups to be implemented must also be connectable to existing electricity, water and lubricant connections at the scaffolding point of the finished assembly.
  • the bar steel mill comprises two or more intermediate stages with different, but staggered, same stand groups, the stand groups of the first intermediate stage following the preliminary stage usually being provided with rollers of larger diameter than those of a subsequent intermediate series and thus being heavier than their rolling stands, that two or more different scaffolding points for the optional accommodation of a scaffolding group and self-propulsion of one or the other intermediate series are accordingly arranged behind the cooling section, ie that a suitable scaffolding point is available both for the heavier scaffolding groups and for the lighter scaffolding groups.
  • the scaffolding groups to be implemented all have their own drive, so that no precautions with regard to the drives have to be taken for this at the scaffolding point or scaffolding behind the cooling section. It is different, however, if an intermediate season consists of the same stand groups, each with a pair of vertical and horizontal rollers, which are driven by a stationary group drive. In this case, it is necessary that a scaffold location suitable for all scaffold groups to be implemented is arranged behind the cooling section with a drive suitable for all these scaffold groups, i. H. that all scaffolding groups to be implemented can be connected or coupled to the drive assigned to the scaffolding location behind the cooling section.
  • the invention provides for a bar steel rolling mill with two or more intermediate stages with different, but staggered same scaffolding groups with different stationary group drives, that two or more different scaffolding points are behind the cooling section the drives adapted to the group drives are arranged for optionally accommodating a scaffolding group of one or the other intermediate group.
  • the overhead crane is to be used for moving scaffold groups with individual or group drives from the one or more intermediate stacks into the scaffolding points arranged behind the cooling section.
  • the invention also shows a way to implement scaffolding groups without crane work if a steel bar mill for carrying out the method according to the invention with quick-change devices for rolling is provided with stands, which are provided with running wheels, so that rolling stands can be moved out of the rolling line via pairs of rails extending transversely to the rolling line and can be slid onto a pair of rails which can be moved on a pair of rails extending parallel to the rolling line, the pairs of rails extending transversely to the rolling line are extended beyond the crossing regions with the pair of rails extending parallel to the rolling line.
  • any scaffold group to be moved can be moved using the trolley and of the pair of rails which extend to the finished series and which runs parallel to the rolling line, are moved back into the suitable stand of the finished group behind the cooling section in the rolling line.
  • Such a combination of quick-change devices for each intermediate season and the finished season can also be advantageously used for a bar mill in which the mill is not to be thermo-mechanically finished, ie which does not have a cooling section directly upstream of the season.
  • Fs is also recommended for dimensionally stable finish rolling in the stand or stands of the finishing train that behind the stand or stands a stand group with dimension caliber rolls, which can be extended in the expansion position, is arranged, which can be used, in particular, for the small rolling stock dimensions.
  • the rolling mill shown in Fig. 1 consists of a preliminary assembly 1 with eight rolling stands, of which only three are shown, an intermediate assembly 2, a lighter intermediate assembly 3, a finishing assembly 4 for steel bars and a wire finishing assembly 5.
  • the rolling stands of the preliminary assembly, the intermediate assemblies and of the finishing line 4 are arranged on the straight rolling line 6, whereas the wire finishing line 5 is arranged on a rolling line 7 offset from the rolling line 6, into which the rolling stock can be deflected via a switch arrangement 8.
  • Behind the intermediate season 3 there is a water cooling section 9 for setting the rolling stock temperature to a value of approx. 750 degrees Celsius in order to finish-roll the rolling stock with the same low temperature in the finishing season 4 or the finished wire season 5 and thus a fine-grained structure that is favorable for further processing to obtain.
  • the heavy intermediate season 2 consists of stand groups 12, 13, 14 with vertical and horizontal pairs of rolls which are successive in the rolling direction and which are driven together by a group drive 20.
  • An additional water cooling section 10 is located behind the heavy intermediate tier 2.
  • the lighter intermediate group 3 consists of stand groups 15, 16, 17, which differ from the stand groups 12, 13, 14 of the intermediate group 2 only in that the roller diameters are smaller and the stand groups are therefore lighter. Accordingly, the group drive 21 is also designed to be lighter than the group drive 20 of the intermediate series 2.
  • two scaffolding points 22 and 25 are provided, behind which a scaffolding group 24 with caliber rollers is arranged.
  • the stand 25 is occupied by a light stand group, which is not shown in FIG. 1.
  • the dash-dotted representation of scaffolding groups in the scaffolding points 22 and 25 is intended to make it clear that one of the scaffolding groups 12, 13 or 14 of the heavy intermediate season 2 can be inserted into the scaffolding point 22, whereas the scaffolding point 25 is set up for this, optionally one of the scaffolding groups 15, 16 or 17 of the light intermediate season 3 to record.
  • the scaffolding points 22 and 25 are accordingly not only for the optional inclusion of either scaffolding groups 12 to 14 or scaffolding groups 15 to 17 are set up, but these scaffolding groups are also the same among themselves with regard to their roller stands, their drive couplings and the required power, water and lubricant connections, so that they can be converted into the scaffolding point 22 or 25 are appropriately prepared.
  • the heavy intermediate season 2 is assigned a quick-change device 26, which consists of pairs of rails 27, 28 and 29 extending transversely to the rolling line 6 for each stand group 12, 13 and 14. These pairs of rails cross a pair of rails 38 which extends parallel to the rolling line 6 and on which a carriage 40 with a pair of rails 41 is movably arranged.
  • a quick-change device 30 with pairs of rails 31, 32 and 33 extending transversely to the rolling line 6 is also assigned to the light intermediate season 3.
  • the scaffolding points 22 and 25 are provided with pairs of rails 35, 36 for moving in and out scaffolding groups. All quick-change devices 26, 30 and 34 are connected to one another via the pair of rails 38 extending parallel to the rolling line 6.
  • the pairs of rails 27 to 29, 31 to 33 and 35, 36 extending transversely to the rolling line 6 are extended beyond the crossing regions with the pair of rails 38.
  • the scaffolding group located in the scaffolding point 25 is extended into the extensions of the rail pair 36 beyond the area of intersection with the rail pair 38, in order to clear the way for the carriage 40, which with its pair of rails 41 is on the escape line of the latter Rail pair 31, 32 or 33 is moved, which is assigned to the scaffolding group 15, 16 or 17 to be implemented. If, for example, the scaffolding group 17 is set to an outlet cross section which is at the same time the finished cross section of the next larger bar steel dimension, this scaffolding group 17 is moved by means of the carriage 40 to the side of the scaffolding point 25, in order then to be moved into the scaffolding point 25. It is understood that the scaffolding groups are provided with impellers, as shown in Fig. 2 for a self-propelled scaffolding group.
  • all scaffolding groups can be provided with carriages serving as roll stand supports, which are provided with axleless wheels and allow displacements along and across the rolling line 6.
  • the scaffolding group 17 located in the scaffolding point 25 is returned to the carriage 40 and the carriage is moved back to the crossover area between the pairs of rails 33 and 38.
  • the scaffolding group 17 is then removed on the extensions of the pair of rails 33 into a kind of waiting position in order to clear the way for the carriage 40 to implement the scaffolding group 16 into the scaffolding site 25.
  • all other scaffolding groups 15, 14, 13 or 12 can be implemented as finished scaffolding in the scaffolding points 25 and 22, whereas the scaffolding point 22 - as stated - is reserved for the scaffolding groups 12 to 14 of the heavy intermediate relay 2, the scaffolding groups 12 , 13 or 14 can be moved into the scaffold 22 via the pair of rails 35. All stands that are not required are in waiting positions on the extensions of the pairs of rails extending transversely to the rolling line 6 beyond the crossing areas with the pair of rails 38 connecting all quick-change devices.
  • each stand group of the intermediate groups is expediently adjusted from the calibration point of view that the outlet cross section is a finished cross section provided in the rolling program, which is only reworked by a sizing roll caliber of stand group 24, if necessary. Only this stand group 24 with sizing roll calibres may need to be set up for the respective bar steel dimension. Depending on the structure of the rolling program, it may be necessary to increase the number of stand groups in the intermediate groups 2 or 3 in order to always use their stand groups as the finished group 4.
  • the most important advantage of the method according to the invention which can also be carried out by moving scaffolding groups 15 to 17 or 12 to 14 by means of a crane, is that the finishing stitches can be carried out behind the water cooling section 9 without the finishing squad on the respective finished cross-section must be set up, for which purpose changing stands would have to be provided for the finished batch, if it should not be converted within the rolling line.
  • the use of the quick change devices 26, 30 and 34 with which all quick change devices Direction connecting rail pair 38 not only has the advantage that any crane work is avoided, but it also makes it possible in a conventional manner to work with interchangeable scaffolding while saving on scaffolding points in the intermediate stages 2 and 3. Instead of scaffolding groups not required in the intermediate stages, special channels are expediently installed.
  • the switch arrangement 8 is simply actuated in order to transfer the rolling stock into the deflection channel 7.
