Definitions

  • the present invention relates to a device for casting a steel or metallurgical container such as a continuous casting distributor or a ladle.
  • a pouring device comprises elements of refractory material traversed by a pouring channel which ends in an external tube called an external nozzle.
  • an external nozzle During the casting of molten metal the refractory wall of the pouring channel and of the external nozzle is eroded considerably under the effect of the high temperature of the liquid metal and, in particular, the external nozzle must be replaced frequently. This is why a means is provided to make the replacement of the external nozzle as fast as possible so as to minimize the immobilization time of the container, and in particular in the case of continuous casting.
  • the document EP-A-0122904 on which the preamble of claim 1 is based, describes a device for closing the pouring channel of a steel container, comprising a fixed plate attached under the bottom of the container, a shutter-drawer mounted under the fixed plate to be able to slide along and against it, and a set of base-tube of external pouring held against the shutter-drawer.
  • the entire device is clamped against the bottom of the container by a clamping device which exerts and maintains upward pressure.
  • the seal between the base of the external pouring tube and the shutter-drawer and between the shutter-drawer and the fixed plate is only ensured by the pressure of tightening up. Sealing is therefore dependent on this clamping pressure and when it varies, perfect sealing can no longer be ensured.
  • a variation in the clamping pressure occurs in particular when the external pouring tube is changed. Even using a pouring tube composed of a tubular element separable from a tube-holder base, as explained in document WO-A-89/02800, it is not possible to guarantee a perfect seal regardless of the clamping pressure.
  • the present invention solves this problem by means of a closable casting device for a steel or metallurgical container as defined in the independent claim. More particularly, the invention provides a fixed reference plate rigidly mounted in a box fixed to the container, said fixed reference plate being placed between the shutter-drawer and the base-external-pouring tube assembly and being pierced with a pouring port coaxial with the pouring channel of the external pouring tube so as to be in communication with the pouring orifice of the shutter-drawer when the latter is in its position delivering passage to the liquid metal, means of clamping arranged to push the fixed plate and the shutter-drawer towards the fixed reference plate and keep the shutter-drawer tight against the upper face of the fixed reference plate.
  • the reference plate gives the fixed plate attached to the bottom of the container perfect stability which prevents any lateral or vertical movement of this plate without it being necessary to increase the force of Tightening. In this way, a perfect seal is ensured in the closing device even in the event of variation of the clamping force.
  • the stability conferred on the closure device thanks to the presence of the reference plate in accordance with the invention allows the use of an external pouring tube with variable flow.
  • the invention makes it possible to take advantage of a device for supplying and changing the external pouring tube as described in EP-A-0192019 with a device for closing the pouring channel with obturator drawer thanks to the seal. perfect provided by the device according to the invention.
  • Figure 1 is a plan view of a casting device according to the invention.
  • Figure 2 is a sectional view along line II-II of Figure 1.
  • Figure 3 is a sectional view along line III-III of Figure 1.
  • the embodiment illustrated by way of example represents a casting device for a continuous casting distributor.
  • the bottom of the distributor is designated by the reference sign 10 in FIG. 2.
  • the reference sign 12 designates the internal nozzle which, as is known, is housed in a brick of seat 11 built in the refractory lining inside the distributor.
  • the lower end of the internal nozzle 12 fits into a groove formed on the upper face of a plate 21 of refractory material (called fixed plate) pierced with a pouring orifice 14 coaxial with the pouring channel 13 of the nozzle internal 12.
  • the fixed plate 21 is fixed in a support ring 28 held in a box 20 as will be seen below.
  • a movable plate 22 of refractory material pierced with a pouring orifice 15 which, in the position shown in FIG. 2, is coaxial with the pouring orifice 14 of the fixed plate 21.
  • the plate mobile 22 is mounted so that it can slide along the fixed plate 21 in the direction indicated by the arrow M in FIG. 3 (that is to say the direction perpendicular to the plane of the drawing in FIG. 2), under the action of a push arm 27 controlled by a drive mechanism known per se.
  • the movable plate 22 comes to close off the pouring channel.
  • a fixed plate 23 of refractory material pierced with a tap hole 16 which communicates with the pouring orifices 14 and 15 and the pouring channel 13.
  • the plate 23 is rigidly fixed to the box 20 as shown in particular in Figure 3.
  • the fixed plate 23 serves as a reference plate for mounting the device as will be seen later.
  • a base 24 made integral with a pouring tube 25 or nozzle external.
  • the base-nozzle assembly is put in place by horizontal translation by means of a pushing arm 18 and it is held by arms forming part of the casing 20.
  • the pouring channel of the external nozzle 25 communicates with the pouring channel 13 of the internal nozzle 12.
  • the fixed plate 23 intermediate between the movable plate 22 and the base 24 of the nozzle 25 serves as a common reference plate for tightening the entire device inside of the box 20.
  • the base-nozzle assembly 24-25 is carried and tightened against the underside of the reference plate 23 by pushing upwards exerted by the end of the arms 33 which are armed by the action of springs.
  • the fixed 21 and movable plates 22 of the closure device are carried and clamped against the upper face of the reference plate 23 by pushing downwards exerted on the support ring 28 which maintains the fixed plate 21.
  • the crown 28 is held in position by the pressure of the springs 35, the force of which is transmitted to the crown via the pushers 36 mounted around a pivot axis 37.
  • the springs 35 and the pushers 36 are six in number.
  • a screw 31 (visible in FIG. 3) exerts on the crown 28 a force which has a vertical component; this produces a low downward pressure which stabilizes the crown 28 during the sliding of the movable plate 22.
  • the fixed plate 21 is perfectly stabilized, thus avoiding any lateral or vertical movement of this plate without the need to increase the clamping force.
  • FIG. 3 shows by way of example an embodiment in which the axis BB of the nozzle 25 and the orifice of the reference plate 23 is offset with respect to the axis AA of the pouring channel 13 of the internal nozzle 12.
  • a screw 34 makes it possible to block the horizontal position of the reference plate 23 so as to maintain it in position during the movement of the movable plate while ensuring excellent sealing.
