Definitions
- the invention relates to an immersion nozzle for metallurgical vessels, in particular for a storage container arranged upstream of a continuous casting mold, to which the rusgie tube is sealingly attached to a perforated brick and can be replaced or inserted into a perforated brick.
- the basic body of such a russia tube consists of alumina-graphite materials with high wear resistance against liquid steel and protection of the graphite component against burnout and solution in the steel.
- Rusgieprohre in the Rus enclosureform as immersion spouts for so-called slab cross sections i.e. e.g. Cross sections of 300 mm ⁇ 2600 mm require a suitable geometric design in terms of their casting performance.
- the internal cross section is designed so large that the required casting power is maintained that alumina deposits do not lead to restrictions in the pouring speed.
- mold cross sections become smaller, e.g. 50 mm mold width, the dimensions and therefore the flow cross-sections of an immersion nozzle must be reduced.
- the tubular shaft which begins with a flange or with an insertion cone, is divided into an upper longitudinal section and a lower longitudinal section, the upper longitudinal section being narrow in a first longitudinal sectional plane and the lower longitudinal section in the same first longitudinal sectional plane is the same or wider and the upper longitudinal section in a second longitudinal sectional plane perpendicular to the first longitudinal sectional plane is wider than the lower longitudinal section lying in the same second longitudinal sectional plane.
- Another advantage is the interaction with a smooth-walled continuous casting mold, the manufacturing costs of which are correspondingly low.
- a favorable flow distribution is also achieved in that the upper longitudinal section is round in cross section and the lower longitudinal section is rectangular in cross section, a conical transition being provided between the two longitudinal sections.
- At least the wall thickness of the lower longitudinal section is at most 10 mm.
- the lower length section is at least partially made of a refractory, thermo-shock-resistant and resistant to powder powder Material consists, zirconium oxide being provided as the main component and graphite and / or silicon carbide and / or boron nitride and / or refractory metals and / or refractory metal compounds being provided as additives.
- a map taking relating to the professional manufacture of the pouring tube consists in that the upper longitudinal section and the lower longitudinal section can be produced by means of divisible core segments.
- the flow opening is correspondingly narrow and can be up to 10 mm and less.
- a flow-oriented cavity is advantageously produced by means of assembled core segments.
- the steel core has an axially removable central core and side cores that can be pulled out through the mouth openings as well as secondary cores that can be moved into the center and then also axially pulled out from there.
- 1 is a vertical longitudinal section for the pouring tube in the operating position (shown for a stopper control) 2 shows a horizontal cross section corresponding to the section line II-II in FIG. 1,
- FIG. 3 shows a longitudinal section perpendicular to the plane of FIG. 1 corresponding to the section III - III in FIGS. 1 and
- Fig. 4a is a view of the arrangement of the steel core for the embodiment according to Fig. 1 and
- FIG. 4b is a side view of the steel core belonging to FIG. 4a.
- the pouring spout 2 which is also referred to below as diving outlet 2a, is attached to a perforated brick 1 of a storage container.
- the type of fastening or the fastening means depend on whether a plug closure 3 or a slide closure (not shown) is used.
- an inlet tube A is embedded for the plug closure 3 in the perforated brick 1, which penetrates the sheet metal jacket 5 and is spherically shaped at its lower end 4a.
- a first holding plate 7 is inserted laterally in a groove 6.
- a second holding plate 6 engages, which presses the pouring pipe 2 or the flange 2b against the spherically shaped end 4a of the inlet pipe A by means of threaded screws 9.
- a sealing seat 10 is created by the concave inner shape 2c, which is papered onto the spherical shape of the inlet pipe end 4a.
- the pouring tube 2 which is shown in FIGS. 1, 2 and 3 as diving outlet 2a, forms below the holding plate 6 a tubular shaft 11 which is structurally divided into an upper length section 12 and a lower length section 13.
- 1 forms a first longitudinal sectional plane in which the upper longitudinal section 12, apart from a conical transition 14, is narrow in the region 15 and the lower one Longitudinal section 13 has a much wider area 16 than the narrow area 15.
- the difference in widths between the areas 15 and 16 results from the length / width ratio of 20: 1 to 80: 1 in the mouth area 17 compared to the flow cross section 16 of the inlet pipe 4.
- the lateral mouth openings 19 and 20 together have a flow cross section that is not quite as large as the flow cross-section at the plug closure 3.
- the orifices 19 and 20 can of course be even smaller, since the plug closure 3 exerts a corresponding control over the liquid metal component flowing through per unit of time.
- the plug seat on the plug lock 3 can be approximately 4400 mm 2, the inner diameter 21 of the area 15, for example, 95 mm diameter.
- the orifices 19 and 20 have a flow cross section of approximately 2600 mm 2.
- the values given relate to a continuous casting mold 22 (FIG. 2) with a casting opening of 50 mm ⁇ 1600 mm.
- the conical transition 14 is made, similar to the mouth region 17, from a material which is resistant to thermal shock and to flowing steel, as described above, while the region 16, in which the mirror 23 is located, is made from a material which is resistant to the slag 24, which is achieved by the different hatching directions should be highlighted in the drawing.
- the wall thickness 25 to the left and right of the flow cross section 26 is approximately 10 mm for a 50 mm wide insertion opening 27 of the continuous mold 22.
