Definitions

  • the invention relates to a working method for heat transfer between semi-finished products cast in continuous casting devices and, after their introduction and processing in forming devices, for example, rolling devices, forming a further group, in which heat transfer is effected between these semi-finished product groups, which have different temperatures from one another .
  • buffer stores are arranged between the continuous casting device and these or associated heating furnaces, with which the differences in capacity based on the differences in the spreading and further processing speeds are compensated (DE-OS 27 23 626). It is also known to utilize the continuous casting heat of the semi-finished products in such a way that already cooled and still warm semi-finished products are introduced into one and the same heating furnace, which results in a shortening of the heating time to the desired processing temperature, or the warm introduced semi-finished products are shorter Warm oven linger than the cold ones.
  • JP-A-60-52201 it is also known to heat continuously cast semifinished products, which have already been subjected to a rolling process and have subsequently been cut to length, by such semifinished products which have a higher temperature when they come straight from the continuous casting installation.
  • the semifinished products are alternately layered and applied to a transport trolley, the semifinished products of higher temperature giving off heat to the semifinished products of lower temperature by touching the superimposed surfaces, thus allowing, for example, subsequent rolling of the batch located on the transport trolley.
  • the working method according to the invention brings with it the possibility of completely unlocking the flow of the semi-finished product length groups between the various casting, forming, heating, storage and other further processing devices and thus directing and controlling this flow in accordance with the particular circumstances and requirements that, in addition to the continuity of the flow, there is an optimal utilization of the heat introduced or of the heat newly introduced during the forming and / or heating process.
  • the continuity of the supply of semifinished length groups coming from the continuous casting device to a forming device (rolling mill) can be achieved by heat transfer from this semifinished length group to temporarily stored, cooled or still warm other semifinished length groups during transport or even at a standstill, if necessary using a reheating unit upstream of the forming device.
  • the semi-finished products can also be slowly cooled and also slowly heated by the workflow achieved according to the invention, if desired, there are particular advantages in the treatment of stainless steels.
  • the inspection and cleaning work can be carried out on the cooled semi-finished products outside the material flow.
  • the working method according to the invention enables a warm use of the semi-finished products that is considerably higher than the 30% that can be achieved so far.
  • the formed (rolled) lengths of semi-finished products then pass through a roller table R5 into the thermal insulation chamber WK2 or via a roller table R9 into the thermal insulation chamber WK3.
  • the semi-finished product length groups that entered the thermal insulation chamber WK2 are brought into heat transfer contact by transverse transport with the semi-finished product length groups coming from the warehouse L4 via a roller table R8 and then fed via a roller table R7 to a warehouse L3, while the semi-finished product lengths coming from the warehouse L4 are heated by this process -Groups are fed via the roller table R6 a pre-heating unit NW2 upstream of the finishing mill FW1.
  • the process runs as in the thermal insulation chambers already described WK1 and WK2 from.
  • Fig. 2 shows an arrangement in which the waste heat of the semi-finished product groups to be cooled is used to preheat the semi-finished product groups to be introduced into the heating furnace.
  • These are fed via a roller table R14 to a thermal insulation chamber WK4, brought into heat transfer contact by transverse transport with groups of semi-finished products coming from the warehouse L7 via a roller table R13 and then fed to the warehouse L8 via a roller table R16, while the heated semi-finished products coming from the warehouse L7 Groups are fed via a roller table R15 a heating furnace WO.
  • the support grid below intended for the warm semi-finished lengths HW coming from the continuous casting device (not shown), has grate bars 1 which are arranged at a distance DK from one another, while the overlying grate which receives the semi-finished lengths HK coming from the store only has one here Has a pair of grate beams 2, which rest at a distance DG on the support beam 4 connected to the foundation 3.
  • the lower support grid with the grate bars l is assigned a roller table R 1, which transports the (see FIG. 1) semi-finished lengths HW coming from the continuous casting device ST in the direction of their longitudinal axis.
  • the hot semifinished product lengths HW on the lower support grate with the grate bars l heat the semifinished product lengths HK that are transported in opposite directions on the grate bars 2 of the upper support grate in the direction of arrow P2 before they are fed to the processing system or a heating furnace.
  • Both support grids are enclosed by a thermal insulation chamber 9.
  • the considerably larger distance DG of the pair of grate beams 2 of the upper support grate is dimensioned such that it leads to a permissible sagging of the overlying semi-finished lengths, but thereby ensures uniform heating of the individual semi-finished lengths HK over their length.
  • the arrangement is such that the warm semifinished product lengths HW coming from the continuous casting device are carried by the rollers R of a roller table and are transported through the thermal insulation chamber 9 in the direction of the arrows P1 (FIG. 5), while the semi-finished lengths HK coming from the warehouse are carried by an independently driven roller table (not shown) in the direction of arrows P2 in the opposite direction and in each case lying between two warm semi-finished lengths HW and are heated from both sides by the warm semi-finished lengths HW through heat transfer contact. Assign the semi-finished lengths to be treated HW and HK rectangular cross-sections, then they are expediently transported upright and, as can be seen from FIG.
  • the hot semi-finished product lengths coming from the continuous casting device can, if necessary, be fed directly to the further processing plant, here the finishing mill, in such a way that the described devices work in circulation in order to compensate for the differences between the Compensate the discharge capacity of the continuous caster and the acceptance capacity of the processing plant.
