Definitions
- the invention relates to a device for supplying molten metal, in particular of liquid steel, via immersion pipes in intermediate containers in a stationary mold of a slab caster, the intermediate container as pouring chamber provided with a vacuum pump, that with a main chamber is connected, in which the melt is supplied from the outside, is formed.
- Such a device is known from FR 2675411.
- the main outlets of the pouring tubes are on the side opposite one another arranged.
- the disadvantage of this pouring system are the relatively large pouring tubes that require an extended mold pouring area.
- a continuous caster is known in which (Figure 1) a ladle steel flows continuously into an intermediate vessel, which is a Has bottom opening through which the steel enters and leaves a fire-resistant pouring tube flows into a water-cooled, straight, vertically arranged oscillating mold.
- Figure 5 two pouring tubes are used. Above the Bottom opening is a fire-proof pipe at a distance from the top edge of the bottom opening bringable, whereby inert gas can be fed into the pouring stream via this tube.
- the disadvantage of this facility is the large geodetic height above the mouth of the Submerged pouring tube and thus the large kinetic energy that a pouring tube or two pouring tubes acts on the molten steel in the mold.
- DE 195 12 209 discloses a method and a device in which metallic melt, in particular steel, via a from a casting container attached immersion pouring tube is guided into a vertically oscillating mold.
- the Dip tube has a cross-sectional area that is not smaller than that 0.3 times the free inner cross section of the passage area of the mold. That about this
- the immersion pouring tube used is similar in cross-section to the mold and therefore has a significantly larger width than thickness.
- Disadvantage of this configuration of the Immersion tube is the relatively large unsupported area and beyond relatively sharp edges in the area of the narrow sides with regard to the break resistance of the Refractory material with the desired wall thickness.
- FR 2675411 is also a device for supplying molten steel known, with a lower and upper container, via a connecting line are interconnected. There is one on the lid of the upper container Vacuum device provided with which the melt from the lower container can be lifted and guided into a mold via a diving spout.
- This system is connected to gas supply elements and serves essentially the Treatment of the steel before it is passed through a dip tube not described any further is led into the mold.
- the invention has set itself the goal of a device for feeding To create molten metal, especially of liquid steel, in which with simple, cost-effective feeding elements a safe feeding with low kinetic energy the melt is reached in a mold with high operational reliability.
- the melt is kept under vacuum Intermediate containers via at least three immersion pipes arranged side by side led into a mold.
- a melt amount to several subsets over several immersion pipes Possibility to directly influence the flow direction and quantity of the partial flows to be taken, at the same time connecting the largest possible entry cross-section of the feed elements into the mold.
- a large feed cross-section with simultaneous low geodetic height of the liquid level allows a desired, only low kinetic energy and thus minimal penetration depth of the supplied melt into the mold.
- Another advantage of the device according to the invention is the use of geometrically simple elements, such as the circular shape of the immersion pipes or almost round shapes or rectangular, with very similar length / width ratios.
- the immersion pipes can be arranged in a line next to each other in a row his.
- the immersion pipes are in two Lines arranged, with an odd number of tubes in one line and one even number are provided in the other line.
- the Distance between the immersion pipes in the middle area of the mold Narrow sides can be changed.
- the diameter of the immersion pipes can also chosen differently from each other and the respective flow conditions be adjusted.
- the immersion pipes at an angle to the main mold axis adapt according to the desired flow conditions.
- Another Variation consists in changing the length of the individual immersion pipes. In one variant is the shortest immersion nozzle in the center of the mold. To a completely Another flow occurs when the immersion pipe varies in length be that the longest immersion pouring tube is arranged in the middle of the mold and the shorter near the narrow side walls.
- immersion pouring tubes are proposed, which one have a rectangular cross-section, the individual immersion pipes being the same Design be positively attached in the intermediate container. Functionally this creates a diving spout with a very large ratio of width to width Thickness, but the individual elements due to their almost square shape have a particularly long service life.
- actuators are provided in which the flow of the individual immersion pipes can be changed to completely closable In this way, the flow rate can be changed during operation are closed or in the event of defects of individual immersion pipes, each of these is closed without interfering with the entire operation.
- Figure 1 shows a pan 11, the bottom opening 12 through a plug 14th is lockable.
- a diving spout 13 is attached, which in a Main chamber 23 of an intermediate container 21 protrudes.
- the intermediate container 21st also has a higher level than the main chamber Pouring chamber to which a vacuum pump 27 for lifting the liquid melt connected.
- a vacuum pump 27 for lifting the liquid melt connected.
- bottom 24 of the pouring chamber 22 there are bottom openings 25 provided, are connected to the immersion pipes 31 to 3n, which in a Protrude mold 41.
- FIG. 2 shows the pouring chamber 22 on which an odd number of Immersion pouring tubes 31 to 35 are arranged, which protrude into the mold 41.
- the middle pipe 33 At this in-line immersion pouring pipes 31 to 35 is the middle pipe 33 at longest.
- FIG. 3 shows an even number of immersion pipes 31 to 34, in which the middle tubes 32, 33 are shortest.
- FIG. 5 shows an even number of immersion pipes 31 to 34, where pairs 31, 32 and 33, 34 converge the immersion pipes to each other.
- an odd number of immersion pouring tubes 31 to 33 are arranged in a line L 1 in series, the distance a 1 from one another in the present case being greater than the distance a 2 from the outer immersion pouring tube 31 or 33 to the narrow side 44 of the Mold.
- an even number of immersion pouring tubes 31 to 34 are arranged in a line L 1 , the individual immersion pouring tubes 31 to 34 having different diameters, in the present case the middle immersion pouring tubes 32, 33 are larger in diameter than the outer immersion pouring tubes 31, 34.
- an odd number of immersion pipes 31 to 35 is provided, the are arranged in two lines L2, L3, the immersion pipes with the odd Number 31, 33, 35 in line L2 and the immersion pipes with even numbers 32 and 34 are arranged in line L3.
- the distances between the individual immersion pipes 31 to 35 including the distance to Narrow side 44 of the mold 41 and also the diameter of the immersion pipes 31 to 35 constant.
- an odd number of immersion pipes 31 to 35 is provided, which have a shape that is different from the circular shape, essentially here oval.
- the individual immersion pipes 31 to 35 are in a line L1 in series arranged and aligned in the same direction.
- FIG. 11 shows an arrangement of the immersion pouring tubes 31 to 35 in a bent mold 42 for an arc continuous casting installation.
- FIG. 12 shows a section of the bottom 24 of the pouring chamber 22, specifically the bottom opening 25, which is surrounded by a bottom stone 26. Between the Bodenstein 26 and a dip tube 31, a quick release 53 is provided, whose slide plate 54 has the bottom opening 25 in an emergency by an actuator 55 closes.
- FIG. 13 in addition to FIG. 1, with the intermediate container 21 and the Pouring chamber 22 and the main chamber 23 and into the mold 41 protruding immersion pouring pipes 31 to 33 a device for closing the Bottom openings 25 are provided, in the present case by plugs 52 are lockable.
- the bottom 24 of the pouring chamber 22 is designed as a slot in which immersion pipes 31 to 33 are positively connected to one another.
- These immersion pouring tubes have shaped elements that support each other, and a nose 36 that corresponds to a bracket 37.
