Definitions

  • This replacement can be carried out, in a known manner, by positioning a new tube next to the tube to be replaced, then simultaneous displacement of the two tubes, the new chasing the old to take its place under the internal nozzle.
  • the distributor's flow hole Prior to each replacement, the distributor's flow hole is closed, but drops of molten metal may remain at the joint surface, the interface between the pouring holes of the tube and the internal nozzle. These drops which solidify are entrained in the joint surface and deteriorate when read or less severely the contact face of the internal nozzle. As it is not possible to replace the internal nozzle during casting, it is essential to preserve it and in particular its lower contact face so that the seal of the joint surface formed with the contact face of the tube is maintained as long as possible and, by way of consequences, that the casting should not be stopped prematurely.
  • the joint surface has an injection channel for fluid, such as an inert gas, which may have the function, on the one hand, of preventing admission of ambient air in the joint surface and / or allow the injection of a clogging in the joint surface (as shown in documents WO 98/17420 and WO 98/17421), in order to treat cracks which do not fail to propagate in the contact face of the internal nozzle and scratches or scuffs produced during tube changes.
  • fluid such as an inert gas
  • the refractory piece comprises several grooves capable of at least partially scraping the determined part of the face of contact of the other refractory piece.
  • FIG. 1 there is shown the bottom wall 1 of a distributor, in a region surrounding one of its pouring orifices 2.
  • the tapping hole 2 of the distributor is filled by an internal nozzle 9 made of material refractory, which passes through the mounting plate 5 and rests on the underside of this last, by a planar contact face 11.
  • the immersed nozzle 4 on the right is the one that forms, with the internal nozzle 9, a portion of the runner 12 of the molten metal.
  • the one on the left is a nozzle which has just been replaced by displacement in the slide 6 under the action of the jack 8.
  • a stopper 10 can be applied against the upper mouth 13 of the nozzle internal to regulate the metal flow or stop the casting, in particular for allow replacement of the submerged nozzle.
  • the contact face has an injection groove 18 in shape of a portion of a circle on three quarters of a turn, extended by rectilinear portions whose ends 20 are close but do not communicate with each other.
  • a end 20 joins the mouth 21 of a supply conduit, respectively outlet, arranged in the internal nozzle 9.
  • each submerged nozzle constituted by the upper face (along the orientation of FIG. 1) of its flange 7, covers the injection groove 18 of the internal nozzle 9 when the submerged nozzle 4 is in the use position and thus forms a fluid and / or sealing agent injection channel, to combat admission ambient air in the runner and / or against flaring of refractory material constituting the internal nozzle around its cracks, scratches or scuffs 25.
  • the second groove releases not only the part liable to become clogged with the injection groove, but also the mouth 21 of its supply duct, so that the sealing agent, if it is carried away by the fluid, has sufficient volume upon arrival in the injection channel so as not to clump and plug the channel at its Entrance.
  • the slide valve 30 of FIG. 5 is inserted between the internal nozzle 9 and the nozzle submerged 4 described previously.
