Definitions

  • the invention relates to a device for hardening of rolling stock with a large longitudinal extent at high throughput. More specifically, the invention relates to a device for thermal annealing of at least parts of the cross-section over the longitudinal extent of profiled rolling produced in sequence from the rolling heat, in particular for hardening at least the head of rails with a length greater than 50 m and subsequent cooling to room temperature, consisting essentially of a roller table, a means for achsfrowenden alignment of the rolling stock, a means of transport with a support for the rolling stock for transverse displacement thereof, a hardening device with a manipulation arrangement and a cooling bed.
  • a rolling stock is usually subjected to a thermal tempering treatment, which takes place in an advantageous manner using the rolling heat.
  • This compensation which essentially causes an increase in the mechanical material properties, such as hardness, abrasion resistance and the like, can be carried out over the entire cross section or, as is usual in the case of a running rail, only over partial areas thereof.
  • the rolling stock or partial regions of the cross section thereof located in the austenitic microstructure state is immersed over the entire length in a cooling medium and in this way achieves structural transformation in the desired manner.
  • EP-0441766 B1 Devices for carrying out such compensation methods are known ( EP-0441766 B1 ) and have proven themselves in terms of improving the performance characteristics of railroad tracks quite well.
  • the thermal quenching requires a corresponding immersion time or residence time in the cooling fluid, so that the throughput is limited by the tempering device.
  • the maximum possible throughput through a dip-annealer with a Cooling tank limits the performance of the upstream rolling device.
  • Modern rolling mills with upstream heating furnaces in particular for continuous cast starting material, usually have possible rolling capacities which are greater than the throughput of known dip-annealing plants, so that the rolling power must be reduced in a sequential production of hardened rails.
  • the invention now aims to avoid the shortcomings and in particular the economic disadvantages of known thermal treatment facilities for rolling stock of the type mentioned and to provide a device which ensures high quality and good performance of the enforced rolling stock and has a high performance and it makes it possible to treat rod-shaped rod material, in particular rails of lengths over 50 m, from high-performance rolling mills using the rolling heat and to heat-treat the same.
  • the roller table comprises a device for positioning the in at least one cross-sectional area conveyed zuge felicitten rolling in the longitudinal direction and an associated alignment that the curing device arranged at least two side by side with in the longitudinal direction substantially parallel to the alignment
  • Liquid cooling means is formed with manipulators for movement of the rolling stock, that in addition to and parallel to the longitudinal extent of the liquid cooling devices, the laying area of the cooling bed is and that the transverse transport means at least two simultaneously between the roller table rollers movable support arms, each having at its ends disposed there Walzgutauflagen, these conditions on the support arms in the transverse direction of the directional position in the region of the roller table in the laying area of the cooling bed movable, lowered and can be raised so that only the supports the conveying plane of the roller table or Overhang the upper edge of the roller table.
  • the advantages achieved by the invention are, in particular, that in a simple manner with the device in sequence in the transverse transport region of the roller table rolling stock can be positioned and axially aligned with high accuracy, wherein by means of Walzgutauflagen the transverse transport simultaneously, so without Beeint foundedung the setting and the axial straightening process , a previously directed and provided Walzgut can be placed in the storage areas of the cooling devices or from these in the support area of the cooling bed or roller table directly on the cooling bed. It is important that only the Walzgutauflagen the movable between the roles Tragarame of the transverse conveyor over the upper level of the roller table rollers or their promotion level can be raised.
  • the device it is possible to arrange at least two curing devices on one side of the roller table, so that only one side a cooling bed is provided, which provides economic advantages.
  • a rolling stock positioned on the roller table and directed in alignment with the axis can be lifted from it by means of the supports of the support arms and stored, for example, in a storage area of a liquid cooling device designed as a manipulator. Thereafter, the transverse transport means is released for further Walzgutquertransporte, the manipulator alone and automatically set up the stored rolling stock in its cross-sectional position, at least partially bring in the cooling medium, dig out and can provide for transport to the cooling bed.
  • This invention essential separation of transverse transport of the rolling stock even over occupied cooling devices with ultimately a shelf on the cooling bed and an accurate insertion of the rolling stock in the cooling medium improves the accuracy of manipulation and the cooling treatment and leads reliably to hardened rolled products with constant high quality.
  • the performance or the throughput of the device when using two hardening devices next to each other is approximately doubled.
  • the dwell time can be favorably achieved shortened the rail on the roller table, the temperature control improved and, where appropriate, the system performance can be increased. Weiers, this situation is particularly well suited for a so-called "head down" vertical position of the rail by means of manipulators.
  • the bottom side and optionally have sideways effective, horizontally and vertically aligned stops for leveling and alignment of the rolling, especially when cooling of parts of the cross section of a rail a over the length of highly constant cooling and hardness distribution can be achieved, which promotes a quality assurance of the product.
  • FIG. 1 shows a device according to the invention with a hardening device 3 consisting of two liquid cooling devices 31 and 32, which are arranged between a roller table 1 and a cooling bed 4.
  • a hardening device 3 consisting of two liquid cooling devices 31 and 32, which are arranged between a roller table 1 and a cooling bed 4.
  • the head of the rail S is shown immersed in a cooling liquid 315.
  • the rail can be positioned in a dip tank 312 such that exactly only one forced head cooling of the same takes place.
  • stops 313 placed deeper below the surface of a cooling liquid 315, to cool the entire cross section of the rail in a forced manner.
  • a second liquid cooling device 32 stands by.
  • a rail S (not shown) coming from a roll train is positioned on the roller table 1 and can be aligned in alignment with the axis by an alignment means 2, optionally with an alignment ruler 21.
  • a transverse transport means 5 with support arms 51 and in each case one Walzgutauflage 52 is disposed in the region of the roller table 1 traceable. However, it is also possible to determine such a transverse transport means 5 in the region of the cooling bed.
  • a simultaneous displacement of the support arms 51 takes place in such a way that the rolling stock supports 52 arranged thereon raise the rail S from the roller table 1 in alignment while lifting it, and can transversely spend in the direction of the cooling bed 4. It is essential to the invention that in the course of a transverse transport only the Walzgutauflagen 52 of the transverse conveyor 5, even if the pads 52 are moved in the outermost region opposite, for example, when depositing a rail S, a storage area 41 of the cooling bed 4, a conveyor plane 11 of the roller table can project vertically.
  • a positioned and axially aligned rail S which is advantageous in two cross-sectional areas on the conveying plane 11 of the roller table 1, can now in this position by means of Walzgutierlage 52 lifted vertically and substantially horizontally or transversely to a standby liquid cooling device, in Fig. 1 position 32, are spent.
  • Such a cross-sectional position of the rail S on the Walzgutauflagen 52 is favorable for a takeover of the same and a "head down" vertical position by a manipulator 321, by means of which a lowering or insertion of the rail head can be done in a cooling liquid 325.
