Definitions

  • the invention relates to a rolling mill with a hot rolling group, of these upstream furnaces and with at least two continuous casting machines as well as shears in front of and possibly behind the ovens.
  • the length of the furnaces is such that are able to accommodate these opening tapes, which are essentially the Corresponds to the length of each coil to be formed.
  • the first continuous casting machine with the associated furnace in line with the hot rolling group and the second continuous casting machine / furnace group arranged parallel to this shifted.
  • the second continuous casting machine Via ferry cars in the second oven or at the end of these otherwise stationary ovens the forehand from the casting and furnace line of the second strand into the Rolling line to be shifted.
  • a new supporting strip from the other oven be threaded into the hot rolling group for tapping.
  • the threading process represents a disturbance of the stationary casting-rolling process and increases the risk of downtime due to downtime. In addition, there is an increased amount of scrap on the respective Band start.
  • the invention has for its object to propose a rolling mill, which is always repeating at short intervals Threading processes can be avoided without moving in short intervals repetitive, energy-intensive connection processes and with which you can roll almost endlessly.
  • each continuous casting machine have an oven long length is assigned that the furnaces are designed to be transversely displaceable and from the continuous casting lines to those of the continuous casting lines in their position deviating common rolling line can be moved and that the furnaces are longitudinally divided into segments, wherein the segments can be moved individually and independently are.
  • the respective furnace of great length can accommodate pre-strip in lengths, which corresponds to the length of several rolled coils, so that after transfer of the pre-strip from the casting line to the rolling line can be rolled almost endlessly.
  • the cross slide Segments allow parts of the furnace to be moved after the opening in the direction of the hot rolling group, the segments again can be pushed back into the casting line, so that the continuously working casting machines do not need to be stopped.
  • the segments of the ovens can be the same or different lengths have, the different lengths are dimensioned in this way should that the segments e.g. when using two casting machines due to the approximately double casting speed working feeders in their length to the hot rolling group double each time. If three casting lines were used, the Feeder speed approximately three times Casting speed correspond so that the lengths of the segments themselves could triple from segment to segment.
  • This furnace segment can, after the pre-strip has been cut by means of the cutting scissors the feed device are quickly cleared so that the stationary segments, while the sliding segments in the rolling line, can be used as buffers.
  • a corresponding application is also available for the stationary furnace segment the hot rolling group.
  • the figures show a rolling mill 1, consisting of a hot rolling group 2, two ovens, 3, 3 'and two casting machines 4, 4'. Between the casting machines 4, 4 'and the furnaces 3, 3' are scissors 5, 5 ' arranged.
  • the furnaces 3, 3 ' have stationary segments 6, 6', while the Segments 7, 7 ', 8, 8', 9, 9 'and 10, 10' from the casting line 11, 11 ' are displaceable in the rolling line 12.
  • the support strip 13 is immediately after the section through the Scissors 5 shown.
  • the feed device not shown, has the supporting strip from the stationary furnace segment 6 into the furnace segments 7, 8, 9 and 10 moved in.
  • the preliminary strip 13 'in the second casting line 11 'feels approximately half of the furnace 3'.
  • the segments 7, 8, 9, 10 were in the rolling line 12 postponed.
  • the preliminary strip 13 is threaded into the hot rolling group 2 and is hot rolled.
  • the length of the supporting strip 13 ' grows in the oven 3 '.
  • Fig. 3 it is shown that the stationary serving as a buffer Segment 6 is approximately filled with a supporting strip 13 ''.
  • the opening act 13 has already been withdrawn from segment 7.
  • Segment 7 is located on the return path into the casting line 11.
  • the displaceable segment 7 is again in the casting line 11, the stationary furnace segment 6 is already with support 13 '' filled.
  • the displaceable segment 7 is half filled.
  • the supporting strip 13 has already left the displaceable segment 8, which is moved back into the casting line 11.
  • the opening act 13 ' is pushed further into the oven 3 '.
  • the segment 9 ' is approximate filled with the opening strip 13 '.
  • the complete furnace 3 is again in the casting line 11 moved back, the furnace 3 'is now shown in the rolling line 12.
  • the stationary segment 6 'serving as a buffer element becomes already filled with support 13 '' '.
  • the segments 7 ', 8', 9 'and 10' can, after the supporting strip 13 'has expired, one after the other in the casting line 11 'are moved back.
