  • a ladle 1 for casting supplies a reservoir supply 2, also called distributor or distributor, the supply tank 2 discharging the liquid metal 3 in one or several casting lines in one or more ingot molds 4 for casting.
  • the metal supply tank 2 includes a bottom refractory 5, refractory walls 6 intended to retain the molten metal in the supply tank 2, at least one nozzle 7 placed in the refractory bottom 5 which evacuates, by flow, the molten metal from the tank 2.
  • a refractory pad 8 defining a cavity 9 is formed on the bottom 5 of the tank 2. It is intended to receive a jet 10 of molten metal from the pocket 1 moved above the tank 2.
  • the cavity 9 of the pad 8 in the field of the development of steel, as shown in Figure 2, is formed by a buffer bottom 11 and a bulkhead 12 substantially vertical.
  • the buffer is provided on the bottom 5 on the one hand, to receive a jet 10 of molten steel in from the pocket 1 moved above said tank 2 and on the other hand, to ensure a separation of said tank 2 in two spaces, a first space 13 comprising at least one nozzle, and a second space, cavity 9 of buffer 11, confining molten steel, steel which then overflows over the partition 12, in space 13.
  • Buffer 8 is a piece of refractory concrete, which can be in one piece, formed on the bottom 5 of the reservoir and disposed directly above the jet protection tube 10 of ladle 1.
  • the buffer 11, the partition 12 defines the second space is divided into two areas by a barrier 14, a zone 15 receiving the jet of steel 10, and a zone 16 of rising of the metal, located opposite the first space 13 relative to jet 10.
  • Barrier 14 ensures the flow of steel flow from zone 15 to the zone 16 for raising said steel by means of at least one ski lift 19 crossing the barrier 14.
  • the ascent hole 19 of the barrier 14 is located near the bottom of stamp 11.
  • the pad directs the flow of metal entering a movement as represented by arrow A.
  • the buffer comprises, drilled in the partition 12, at least one hole 20 drain ensuring on the one hand, a flow of steel in the bottom 5 of the space 13 of the tank, in particular before the overflow of the steel filling the buffer 8, and on the other hand, a draining of the space 9 of the buffer at the end of casting.
  • the tampon shown in section in the plane containing the longitudinal axis of hole 20, has at least a portion 17 of partition 12 extending above the level 18 of buffer overflow.
  • the stamp can have any geometric shape depending on the shape of the tank. It is preferably parallelepipedic.
  • the tampon according to the invention described above relates to a tampon monolithic that can be placed in any type of tank, without form limitation.
  • the steel contained in spaces that may exist externally between the walls 6 of the tank and the partitions 12 of the pad can flow around the periphery of said pad.
  • the buffer 11 takes, in part, the form of at least one wall 6 of the tank 2 so that the zone 16 for the rise of the steel is located opposite the first space 13 comprising at least one nozzle, relative to the steel jet 10 leaving the pocket 1.
  • the stamp presented on the FIG. 6 is composed of a partition 21 of separation, of a bottom 22, and a barrier 23 defining a C-shaped profile. Zone 16 is formed between a wall portion 6 of the tank and the barrier 23 of the buffer.
  • the stamp is represented in general, in perspective, in Figure 7. As shown in this figure, the tampon can have on the partition 21 a border 24 extending horizontally towards zone 15.
  • the edge 24 can end in a fallen edge 25 closing on itself the flow of steel from space 15.
  • the buffer is composed of a partition 26 for separating a barrier 27 and a bottom 28, in two separate parts, the partition 26 of separation forming an L-shaped profile with a bottom 28 of buffer.
  • the bottom 22 and or 28 constitutes a relatively reserve important of refractory, reserve which mitigates the wear consecutive to the violent impact of the incoming molten steel jet, especially during opening the pocket 1.
  • the buffer is essentially composed of a partition 26 for separation and a barrier 27, the bottom 22, 28 being able be deleted.
  • the bottom 11, 22, 28 comprises, in the area receiving the metal jet, a mass wear 29 comprising at least one inclined face.
  • the tilted pan has for function of orienting the metal jet towards the barrier 14 and the ascent hole 19 crossing the barrier 14.
  • the inclined face may have a face of particular shape such as flat, concave or convex.
  • the proposed tank provided with the buffer according to the invention optimizes the reduction of the turbulence of the liquid steel in the impact zone of the reservoir thanks to the creation of areas of strong energy degradation. he allows the flow of incoming metal to be directed towards the surface and into the direction opposite to the supply nozzles of the casting lines. he also optimizes short circuit times and residence times, which which improves the cleanliness of the steel produced.
  • the tampon can be located in an extreme part of a tank, when the tank has the general shape of an elongated parallelepiped.
  • the nozzles are aligned in the first space which is the T bar.
  • the buffer is then placed in the part perpendicular to the bar of the T, the steel jet melted from the pocket being oriented in the opposite direction at the first space, and after its ascent, moved so that the wave formed orients itself towards the jet from the pocket or cuts the jet transversely from the pocket towards the first space, according to the method of the invention.
