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 casting device comprises elements made 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 does not erode 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. .
- European patent 0192019 describes a device for supplying and exchanging the external pouring tube into a casting device, by means of which the replacement of the external nozzle can be carried out quickly.
- the external nozzle is attached to a removable base of refractory material, this removable base being placed under a fixed plate of refractory material pierced with a pouring orifice and fixed against the bottom of the container.
- a spring mechanism exerts an upward push on the base which carries and clamps the base of the external nozzle against the fixed plate which serves as a reference plate.
- the object of the present invention is to provide the device for supplying and exchanging the pouring tube described briefly above, with a movable member making it possible to close the pouring channel between the container and the external nozzle. .
- Such a shutter member is certainly known per se and consists of a plate of refractory material pierced with at least one pouring orifice and mounted so as to be able to slide by translation or by rotation relative to the fixed plate.
- the sliding plate serving as a shutter is mounted against the fixed plate so that it can slide over the contact surface of the fixed plate while ensuring the most perfect seal.
- This assembly is usually done by pushing the movable plate against the fixed plate which serves as a reference plate for the entire device.
- a closable casting device comprising a fixed refractory plate fixed under the bottom of the container and pierced with a pouring orifice coaxial with the casting channel of the container, and a plate serving as a base for an external pouring tube, which device is re ⁇ markable in that it further comprises a shutter mounted to slide against the underside of the fixed plate, so as to assume a delivering position passage to the liquid metal contained in the container or take a position closing off the casting passage; a fixed reference plate mounted against the underside of the shutter, the underside of the reference plate being placed against the upper face of the base plate, and the reference plate being pierced with a coaxial pouring orifice to the pouring channel of the external pouring tube.
- Clamping means are provided for pushing and holding the base plate against the underside of the reference plate and for pushing the fixed plate and the obturator toward the reference plate and keeping the obturator tight against the upper face of this reference plate.
- 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 interior refractory lining of the distributor.
- the lower end of the internal nozzle 12 fits into a groove formed on the upper face of a plate 21 made of refractory material (called fixed plate) pierced with a pouring orifice 14 coaxial with the pouring channel 13 of the internal nozzle 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 only with the pouring orifices 14 and 15 and the channel of casting 13.
- the plate 23 is rigidly fixed to the casing 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 who are armed by the action of spells.
- the fixed plates 21 and mobile 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 column. 28 which holds the fixed plate 21.
- the crown 28 is held in position by the pressure of the springs 35 whose force 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. Thanks to this arrangement according to the invention, the fixed plate 21 is perfectly stabilized, thus avoiding any lateral or vertical movement of this pla ⁇ that without it being necessary 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.
