Definitions
- the invention relates to continuous casting installations at hot, which are used in particular for the development of raw products in steel.
- An essential element of such an installation is the casting, which we call submerged nozzle.
- a metallurgical or steel container it ensures good distribution of the flow of liquid metal, which must end finally to a continuous casting path, where a progressive cooling and solidification of the metal liquid.
- All parts in contact with metal at high temperature are naturally made of refractory material. They are also subject to wear or plugging, in particular the nozzle, which must be changed periodically to extend the casting sequence.
- a shutter-regulator device for continuous casting hot intended to be mounted on a metallurgical container or steel, and of the type comprising, on a frame, a shutter assembly, a supply path for a tubing so-called submerged nozzle casting, adjacent to the outlet of the shutter, spring plungers to maintain this nozzle in operating position in line with the shutter assembly, on the supply path, which is suitable for receiving another nozzle in standby position, and a cylinder translator offset, fitted with a nozzle drive arm, while bearing on a cam track.
- the body of the jack is fitted at the head with a probe capable of cooperating with the path cam, and also supports the drive arm, while that the cylinder rod is attached to the frame. This reduces the dimensional size of the device.
- the cylinder is contracted when a nozzle is while it is being extended for the displacement of the nozzles by pushing.
- the frame of the device is defined by beams 102 and 103, joined to the right by a crosspiece 101 ( Figure 1), and surmounting parallel lower beams 104 and 105 ( Figure 3). AT left ( Figure 3), the beams are held in place by an assembly comprising elements for guiding a body of cylinder 504 and a frame 106.
- a cover 200 enclosing a refractory piece 201 ( Figures 2 and 3).
- This piece 201 ensures the connection with the refractory of the container under which the device is fixed, so known.
- two other refractory plates are provided. superimposed, 202 and 203.
- the central plate 202 is used to flow control in the nozzle, using a mechanism actuator, not shown here (see EP-B-0 441 927).
- the plate 202 is enclosed in a movable frame which can slide between elements 104 and 105 of the frame ( Figure 3).
- the covers 301 and 302, provided with elastic means of tightening serve to seal between the plates refractory 201 to 203.
- the bus path is visible at the end in 310 on Figure 2.
- Figure 3 we see one of the profiles of guide intended to cooperate with one of the straight edges of the nozzle base: in 320 and 321 profiles slightly ascending, then pushers 323 to 325 (elastic recalls for example in 330 and 340, figure 2), and then a profile exit 326, descending.
- brackets such as 400 (figure 3) which support and guide the translation of the nozzles.
- the head of this cylinder body comprises a 510 tab (figure 3), fitted with a lateral feeler pin 511, which follows a horizontal cam path 520.
- a block 530 articulated around the feeler lug 511, which can also cooperate with an oblique part complementary 521 to the cam path.
- a pusher arm 540 seen in cross section in Figure 3, but visible in Figure 2 in the way of the buses (not shown).
- the end of the cylinder rod is visible at 550 on the figure 3, where it is surmounted by the power system hydraulic 560.
- This system communicates with the rod for ensure the hydraulic supply of the cylinder.
- the stem is fixed or articulated mounting on the frame with the possibility of at least partial angular movement (around an axis horizontal).
- the cylinder When a nozzle (not shown) is in operation, the cylinder is contracted, and is in position A (figures 1 and 3). A new nozzle is waiting on the way supply, in contact with the operating nozzle, on the the cylinder head.
- the pusher arm is located at the top of the path of complementary cam 521, to allow its introduction by pivoting in the molten steel bath, without necessarily raise the dispatcher.
- the cylinder is put in extension, and pushes the two nozzles together, so that the new one comes in the operating position, while the old one exits from the left ( Figure 3), and can then be removed of the steel bath in a known manner. After that, the cylinder can return to the contracted position.
- the device described above is particularly compact.
- the arrangement of the jack contributes to its compactness as soon as a significant part of the body race of cylinder takes place within the dimensions of the rest of the device. It also allows a very quick change of nozzle, which is essential. Furthermore, this change when the cylinder is extended, which allows an operator to provide less pressure force.
- the arrangement of the jack inside the device ensures better protection, in particular of the cylinder rod, by compared to the heat given off by the molten metal.
