Definitions

  • the present invention relates to ladles for molten metal, for example steel, and more particularly to an improvement for cooling the pocket bottom brick of these ladles during their use.
  • the pocket bottom bricks are refractory bricks which line the wall of the pouring channel with the ladles.
  • the contact of air with the refractory brick during casting somewhat erodes the brick.
  • the ladle is returned to maintenance, the pouring channel is still filled with steel which is largely solidified. It is then necessary to burn this steel core using an oxygen lance so as to clean the wall of the pocket bottom brick.
  • the brick is damaged the most strongly because the burner dart causes at the point of contact a very significant rise in temperature and consequently a deterioration of the interior surface.
  • the invention relates to an improvement aimed at allowing the continuous cooling of the pocket bottom brick during metal casting and during maintenance operations so as to protect the wall of this brick against too high a temperature and thus avoid its slow but steady erosion during metal casting and the deterioration of the wall of the pouring channel during maintenance operations.
  • a ladle characterized by an annular cooling chamber extending around the periphery of the pocket bottom brick, a hollow ring being arranged in the annular chamber so as to s extend practically coaxially to the pouring channel, the wall of this ring being pierced with holes distributed along the ring, the interior volume of the ring being in communication with a coolant supply pipe, the wall of the annular chamber having an opening for the evacuation of the cooling fluid distributed by the distributor ring in the annular chamber.
  • the annular cooling chamber can be formed in the pocket bottom brick or be formed by an external box surrounding at least part of the pocket bottom brick.
  • the pocket bottom brick have a longer service life thanks to the significant reduction in the temperature of the wall of the pouring channel, as explained above, but also the plate fixed casting system which adjoins the bottom of the ladle is effectively cooled and thus has a significantly increased service life.
  • the pocket bottom brick 2 is produced with a cooling box.
  • a first embodiment is illustrated in FIG. 2.
  • the brick 2 Over a part of its length, the brick 2 has an annular chamber 3 advantageously furnished internally with a metal box 4.
  • a ring hollow 5 In the upper part of the chamber 3 is arranged a ring hollow 5 which extends in a plane transverse to the axis 1 of the pouring channel 1, practically coaxial with said pouring channel.
  • the cooling fluid for example pressurized air
  • the cooling fluid is thus distributed by the distributor ring 5 around the entire periphery of the brick 2 in the upper part of the annular chamber 3 then, after having bypassed the distributor ring, this coolant circulates throughout the annular chamber 3 down to an orifice d discharge 9 located in the vicinity of the transverse plane in which the lower mouth of the pouring channel 1 is located.
  • the cooling device according to the invention also cools the upper part of the fixed plate 20 of the casting system, which adjoins the bottom of the pocket and the lower mouth of the casting channel 1.
  • the temperature reached by this plate can thus be reduced significantly, which avoids excessive and too rapid wear of the wall of the tap hole 21 of this plate.
  • FIG. 3 shows another embodiment of the device for cooling the pocket bottom brick.
  • the annular chamber 3 in which the distributor ring 5 for the cooling fluid is located is formed by an external metal box 4 which surrounds at least part of the pocket bottom brick 2 and comes to adjoin the fixed plate 20 of the casting system.
  • the reference numerals which are the same as in Figure 2 denote similar or equivalent elements.
  • the coolant introduced into the box 4 by the supply pipe 8 is directed towards the distributor ring 5 by the pipe 7 formed inside the box 4 by an internal metal box 11.
  • the cooling fluid is then distributed in the upper part of the annular chamber 3 through the holes 6 of the distributor ring 5 and descends towards the bottom of the box 4 as shown by the arrows. Part of the cooling fluid is evacuated through the evacuation orifice 9.
  • the inner wall of the box 4 is pierced with several spaced orifices 12, distributed over the entire perimeter so as to let part of the cooling fluid pass to the upper part of the fixed plate 20 of the casting system.
  • An annular channel 13 is advantageously provided practically coaxially with the tap hole 21 of the fixed plate 20 of the casting system to allow the cooling fluid passing through the orifices 12 and thus form a cooling sheath at the top of the fixed plate 20 supra.
