Definitions

  • the invention relates to a device for changing a pouring tube on a metallurgical vessel, in particular a tundish, in which the refractory pouring tube with a head plate can be placed on slide rails which are at least partially spring-loaded on the bottom of the vessel and can be moved into a pouring position with the aid of a drive unit.
  • the pouring tube with its top plate lies sealingly in the region of the pouring opening of the vessel, and in which, if necessary by means of the new pouring tube with its top plate, the used pouring tube with its top plate can be transferred into a removal position with the aid of the drive unit.
  • Such a changing device is known from EP-OS 0 192 019.
  • the pouring tube is brought with its head plate on guide rails into a waiting position in front of the pouring position below the pouring opening of the metallurgical vessel and is shifted from there into the pouring position by means of a pusher device. If the pouring tube is used up, a new pouring tube is brought into the waiting position mentioned and then moved into its pouring position with the aid of the pushing device, the used pouring tube being pressed from its pouring position into a removal position at the same time.
  • the slide plate and the pouring tube with control plate are not interchangeable.
  • the control cylinder is arranged on an intermediate piece, so that the pouring tube with the control plate alone cannot be brought into the control position by the control cylinder; this requires an additional pressure cylinder.
  • a push-through operation for the pouring tube with control plate is not possible despite the relatively complex construction.
  • the object of the present invention is to utilize the advantages of the tube changing device known per se, but to provide them with a further possible use with an essentially constant simple structure and economical operation.
  • This object is essentially achieved in that the maximum metal flow through the pouring opening of the vessel, preferably to zero, can be regulated by moving the pouring tube with its top plate, and in that the drive unit for moving the pouring tube with its head plate into the pouring position serves to regulate the metal flow.
  • the device mentioned at the outset which was previously only suitable for replacing a pouring tube, at the same time has the function of a flow control for the metallurgical vessel, it being understood that the head plate is then appropriately dimensioned to match the pouring opening of the vessel to ensure, for example, that the pouring opening is closed completely and safely.
  • the object is achieved in a particularly simple manner in that the drive unit for moving the pouring tube with its head plate into the pouring position also serves to regulate the metal flow.
  • the handling of the device according to the invention is made particularly simple when the drive unit can be detachably coupled to the pouring tube or to the top plate thereof, so that not only a quick change of the pouring tube with its top plate, but also reliable control of the metal flow is possible.
  • an optionally exchangeable refractory base plate is provided in the region of the pouring opening of the vessel, against which the pouring tube with its head plate lies sealingly in the pouring position.
  • the change device mentioned at the outset can be equipped with an even more extensive control function if, in addition to the pouring tube with its head plate, a refractory base plate can also be placed on the bottom of the vessel, optionally offset in height from one another, at least partially spring-loaded slide rails and with the help of at least one Drive unit is displaceable in the pouring position, in which the pouring tube with its head plate lies sealingly against the base plate and the base plate in turn lies sealingly in the region of the pouring opening of the vessel, according to the invention, in addition to the pouring tube used with its top plate, optionally by means of the new pouring tube with its top plate, with the help of the at least one drive unit, the base plate that has been spent, if necessary by means of the new base plate, with the help of the at least one drive unit in a removal tray llung is transferable, by moving the pouring tube with its top plate and the base plate, the maximum metal flow through the pouring opening of the vessel, preferably to zero
  • the tube changer consequently has the additional function of a type of three-plate slide valve, in particular if the base plate, which can also be provided in this connection, lies sealingly against an optionally replaceable refractory base plate of the vessel.
  • those drive units which are intended for moving the pouring tube with its top plate or the base plate into the pouring position can also be used for regulating the metal flow.
  • the base plate and the pouring tube with its head plate can be displaced relative to one another, if necessary simultaneously. In this way it can be achieved, for example, that the position of the pouring jet does not shift when the metal flow changes.
  • the pouring tube and head plate are preferably formed in one piece, that is to say without a joint.
  • the device shown in Figures 1 and 2 is used to change a pouring tube 1 on a metallurgical vessel 2.
  • the refractory pouring tube 1 has a top plate 3, which is arranged on the bottom 4 of the vessel 2 Slide rails 5 is removable. From there, the pouring tube 1 with the top plate 3 is moved by means of a drive unit 6 into a pouring position in which the top plate 3 lies sealingly in the area of the pouring opening 7 of the vessel 2, in the case shown on a stationary base plate 8.
  • the slide rails are divided into individual spring-loaded rail sections 5 ', which engage under the head plate 3 at its edge and press the top of the head plate 3 against the sealing surface of the base plate 8 facing downward.
  • the pouring tube 1 After the pouring tube 1 has been placed in the left waiting position on the slide rails 5, it can be moved by means of a drive unit 6 attached to the bottom 4 of the vessel 2 into the middle pouring position in which the pouring opening 7 of the vessel 2 with the flow channel 11 of the Pouring tube 1 is aligned.
  • the pouring tube 1 already present in the middle pouring position is pushed to the right onto a slightly sloping rail section 5 '' into a removal position, in which the used pouring tube 1 '' can be removed .
  • the pouring tube 1 'with its top plate 3' can be used according to the invention by pushing the drive unit 6 back and forth (which is indicated by the double arrow R) to regulate the maximum metal flow through the pouring opening 7 of the vessel 2.
  • the maximum metal flow can be regulated to zero on both sides.
  • the pipe changing device differs from that illustrated in Figure 1 in that between the base plate 8 and the head plate 3, 3 'a base plate 10 is arranged, which in turn lies sealingly on the underside of the base plate 8, and on the underside of the top plate 3 'is pressed sealingly.
  • the base plate 10 is in the fully open pouring position illustrated. With the aid of their horizontal displacement of the base plate 10, indicated by a double arrow, the maximum metal flow through the pouring opening 7 of the vessel 2 can also be regulated to zero, if necessary. This is done with the help of the drive unit 9, which also serves to move the base plate 10 into the casting position shown.
  • the drive unit 9 which also serves to move the base plate 10 into the casting position shown.
  • the previously used base plate 10 can be pushed out of its pouring position into a removal position.
