Definitions

  • the present invention relates to a device for clamping a wear element of a sliding closure of a metallurgical container intended for controlling the flow rate of molten metal, consisting of a refractory material possibly surrounded by a metal frame, mounted in a metal frame provided with a bottom wall and lateral stops against which bears at least one wear element.
  • the wear elements essentially an internal nozzle ensuring the connection between the metallurgical container and the sliding closure, an upper fixed plate pierced with at least one orifice opposite the internal nozzle, a sliding plate provided with at least one sliding orifice joined against the fixed plate, possibly a lower fixed plate and a collecting nozzle.
  • These wear elements are made of refractory material surrounded at least partially by a jacket forming a lost formwork. These elements provided with their metal frame are clamped in a support frame.
  • the plates must generally be applied against a bottom formed in the associated metal frame.
  • Known devices do not provide for pushing the plate against the bottom of the frame, an operation generally carried out manually or by pressing during the sliding closure. This process presents the double danger of introducing a human factor and of delaying this setting up action beyond the time of sintering of the grouts ensuring the joints.
  • the present invention aims to remedy the drawbacks described above and proposes a device which makes it possible simultaneously to clamp the plate against the bottom of the frame, to absorb the clearances between the plate and the lateral stops and to wedge the plate in the frame, while avoiding the use of fasteners.
  • a sliding closure device for a metallurgical container in particular a distributor containing a metal bath, essentially characterized in that it consists of a rotary member driving in rotation a cam having an inclined face which repels a face of a wear element based on a substantially parallel flange of the frame opposite the bottom thereof so as to simultaneously press the plate possibly provided with a frame against the bottom of the frame, the clamping of the plate against the lateral stops and the wedging of the plate in the frame .
  • the clamping device has at each end of the central part of the rotary member forming a cam two coaxial pivot axes.
  • the device is mounted in a housing delimited by the frame, in the walls are formed two circular cylindrical orifices coaxial on an axis perpendicular to the bottom of the frame, the large orifice possibly open on the side of the bottom of the frame being intended to receive the large pivot axis to which it serves as a rotation bearing, the small orifice situated on the opposite side with respect to the bottom of the frame having a diameter slightly greater than that of the small pivot axis to which it takes place rotation bearing, the bottom wall of the housing perpendicular to the axis of rotation of the rotary lock being determined with a view to serving as an axial stop for the bearing face of the rotary lock.
  • the cam advantageously has the shape of a helix coaxial with the pivot axes, a flat being formed on the generator cylinder of the propeller in order to allow the introduction of the plate into the frame when the flat is brought opposite the plate.
  • the preferred form is that of a helix with an axis parallel to the axis of rotation of the rotary bolt, the axis of the propeller being eccentric relative to the axis of rotation of the rotary lock.
  • the device can include several clamping devices distributed around the periphery of the plate.
  • FIG. 1 shows a metal frame, generally designated by the reference notation 1.
  • This frame has a bottom wall 2 and lateral flanges 3. It encloses a wear element 4 of a sliding closure for metallurgical container.
  • the wear element is usually a plate of refractory material possibly surrounded by a metal jacket 5.
  • the lateral flange 3 of the frame 1 consists of an angle folded at a right angle intended to reinforce the rigidity of the frame. In the vicinity of opposite corners, there are provided cavities intended to each accommodate a clamping device 6.
  • the wear element consisting of a plate 4 is tightened in frame 1 by the rotary lock 3.
  • the sliding closure is then in the form of a set of parts nested one inside the other. and wedged by a rotary member locking the plate between the inclined face of the cam 7 and the bottom 2 of the frame 1.
  • the plate 4 wedges the rotary lock between the parallel inclined face of the bearing surface 16 of the plate and the bottom 15 of housing 6 '.
  • the size of the clamping device is very reduced both in thickness and in diameter, which makes it easy to accommodate it in existing devices.
  • the rotary bolt 6 must exert on the bearing surface 13 of the plate 1 forces directed simultaneously towards the bottom 2 of the frame 2 and towards the center of the plate 4.
  • two effects can be used independently or in combination to achieve this result.
  • the cam 7 has the shape of a helix coaxial with the pivot axes 8, 9.
  • the rotation of the rotary lock 3 causes a movement of the place of contact of the cam 7 with the bearing surface 13 towards the bottom 12 of the frame parallel to the axis of rotation of the rotary lock 6.
  • the rotation of the rotary bolt 6 causes the displacement of the contact point of the cam 7 and of the bearing surface 13 towards the center of the plate. Pressing one against the other along inclined contact faces, of the cam 7 and of the frame 5 guarantees double tightening towards the bottom 2 of the frame 2 and towards the center of the plate.
  • the cam 7 has the shape of a propeller whose axis is parallel but slightly eccentric relative to the axis of rotation of the rotary bolt 3. This device uses in combination the two propeller and eccentric effects previously described.
  • the new closure device provides significant advantages in terms of robustness, production cost, size and reliability.
  • the rotary lock is massive and can advantageously be made in one piece from the cast metal.
  • Figure 1 shows two clamping devices 6 arranged in the frame 2, diametrically opposite with respect to the plate in a direction spaced less than 30 ° from the axis of the movement of the sliding closure. Such a device makes it possible to uniformly tighten the plate 4 against the bottom 2 of the frame 1.
  • bearing surface 13 can be provided on any other part of the plate 4 and have various shapes provided that it has an inclined face opposite the side opposite the bottom 2 of the frame 1.
  • a similar device can be provided in the large pivot axis 8, in particular in the case where accessibility on the bottom side of the frame proves more advantageous.
  • the large pivot axis 8 is provided with a handle in order to produce rotation.
  • Similar handles can be attached to the small pivot axis 9 provided that they do not have any interaction with the opposite parts of the plate 4 during the operations of the sliding closure.
