Definitions
- the present invention relates to a device for feeding and exchanging a pouring tube into a mold for a continuous casting installation with thin slabs, comprising an upper reference plate applied against the bottom of the pouring container and guide rails capable of transmitting an upward thrust force and of guiding the sliding of said tube and of a replacement tube under the action of a jack, from a starting position to a service position in the casting axis and from said service position to a release position, so as to allow the exchange of tubes without lifting the casting container.
- the invention makes it possible to transpose to the manufacture of thin slabs, the technology of continuous casting with conventional slabs, introduced by European patent nr 192 019, with a view to carrying out uninterrupted casting sequences of several ladles.
- Continuous casting installations using an ingot mold or mold having an elongated rectangular section already exist. They make it possible to produce slabs whose thickness is generally between 150 and 250 mm and whose width can reach 2,700 mm.
- This period of time is sufficient to cause the rejection of a large section of the slab, due to external and / or internal junction marks in the solidified metal as well as surface and internal cleanliness defects due to the interruption of the stable process of continuous casting.
- the present invention relates to continuous casting which is uninterrupted for a long period, making it possible to empty several ladles in a row at a rate ensuring a speed of extraction of the slab such that the quality of the steel remains constant throughout the duration of casting.
- the slab extraction speed remains at all times greater than or at least equal throughout the duration of the casting at a critical speed, that is to say greater than the speed below which the slab is degraded in quality.
- the flared lower part of the body of the pouring tube extends beyond the width of the attached movable plate.
- the flattened shape of the submerged pouring tube makes it easier, over the entire width of the mold, to obtain a regular flow imposed by the constancy of the flow rate and thermal requirements.
- the invention makes it possible to carry out a long continuous casting sequence of thin slabs, that is to say of accentuated rectangular section whose thickness is less than 100 mm.
- These thin slabs are the starting point for the manufacture of flat products, in particular sheet metal rolled on continuous rolling trains.
- This technology makes it possible to prevent the surface oxidation of slabs consecutive to multiple heating of the sheets during rolling.
- the upper end of the pouring tube carries an attached plate having a perfectly flat upper face and forming an integral part of the pouring tube.
- a flared and flattened skirt of the pouring tube does not affect the arrangement of the guide rails or the maneuvers to be performed by pivoting to introduce a pouring tube from a horizontal starting position outside the mold, towards a vertical waiting position inside the mold and to bring a tube from a vertical waiting position next to the tube in the casting position, towards said casting position.
- the invention relates to a method for bringing and exchanging a pouring tube into an ingot mold of a continuous casting installation, as described above and intended for the manufacture of thin slabs.
- a supply and exchange device similar to that described in document EP-A-192 019 or WO 92/00822 is used and the guide rails are placed next to the added plate of the pouring tube in the service position, an auxiliary plate next to which a replacement pouring tube is juxtaposed, so that said plates form a perfectly flat surface with a joined edge.
- the auxiliary plate has the same template as the guide rails and a longitudinal dimension, at least twice the overflow of the flared part of the body of each of the pouring tubes.
- FIG. 1 is a view in longitudinal section of a supply and exchange device according to the invention of a flared pouring tube placed in the service position under a pouring container and of an auxiliary plate in waiting position;
- Figure 2 is a section similar to that of Figure 1 of the device according to the invention, packed, comprising a booster plate and a replacement pouring tube;
- Figure 3 is a plan view of the device shown in Figure 2;
- Figure 4 is a sectional view similar to those of Figures 1 and 2 of the device according to the invention in which a cylinder has operated the change of tubes.
- the same reference notations designate identical or analogous elements.
- FIG. 1 shows a device for supplying and exchanging a pouring tube according to the invention, generally designated by the reference sign 1, shown under a tapping distributor 5 in the vicinity of the tapping hole 7.
- an ingot mold 8 of a continuous casting installation intended for the manufacture of thin slabs provision is made to give the pouring tubes 2, 12, in particular at the lower end of the tubular body, a flared shape 18 and flattened as a butterfly .
- the distributor 5 is generally provided with a stopper rod not shown. Sometimes it is also fitted with a sliding closure device.
- the supply and exchange device 1 is intended to allow the supply of a replacement pouring tube 2 attached to a plate 3, in the waiting position in the ingot mold next to a tube in position service and the exchange of the used service tube 12, attached to a plate 13, in the service position 14 without raising the distributor ( Figure 2).
- the insert plate and the auxiliary plate 4 are moved by sliding along the reference plate 6.
- the thickness of the auxiliary plate 4 is chosen to be equal to that of the added plate 3, but a slight difference in thickness has no unfortunate consequences due to the fact that in the immediate vicinity of the tap hole, this plate button 4 is pressed up.
- the edge of the auxiliary plate 4 serves as a sliding shoe in the device for feeding and loading tubes.
- Two guide rails 9 have an inclined stroke relative to the reference plate 6.
- the guide rails 9 are divided into two sections, one fixed-19, integral with a frame intended to be mounted under the distributor and the other mobile 29 and disposed between the two respective fixed rail sections in their mutual extension.
- the sections of guide rails29 are each mounted at the end of a horizontal lever pivoting around a fulcrum fixed to the frame. Each lever 11 is subjected to the action of a spring 10 which, directed downwards, applies the sections of movable guide rails29 upwards.
- the force exerted by the sections of movable guide rails 29 on the pouring tubes 2 varies according to the position of said tubes along the guide rails and increases as the replacement pouring tube 2 approaches the hole of flow 7 and decreases as the worn tube moves away from it.
- the jack 16 is shown when it returns to its initial position in which the push rod 15 ensures, thanks to its high position, free access to the loading position 24 of the pouring tubes on the guide rails 9.
- a rocker arm ensures parallelism between the movable plate 3 and the upper reference plate 6 from the start of the operation of supplying and loading the replacement pouring tube 2.
