Definitions
- the invention relates to a cold extrusion head sealing system in a mold of a continuous casting for casting large-size Vorprofile, with a gap between the cold rod head and the mold sealing flat gasket, and a flat gasket at the cold strand head festhaltenden packaging plate, which has approximately the cross-sectional shape of the mold profile and the flat gasket vollumfnaturelich covered.
- Continuous casting plants of this type are used, for example, for producing large so-called beam-blank formats with a double-T profile of more than 800 mm in length, over 400 mm flange width and about 120 mm Web thickness used.
- the cold strand head is known sometimes serves to close the mold before and during the Angiessvorganges down tightly.
- the cold extrusion head with the associated packaging is mounted before Giessbeginn above the mold and then fed into the mold until it has reached the Angiesswolf. Since the packaging is rigid in the known systems, there is formed by the taper of the mold a gap on the inner shoulder of the profile. For large formats, it has an impermissible gap width. Especially in the Angiesswolf but the cold strand packaging must seal properly, to prevent melt flows out of the interior of the mold during casting. The previously known systems are therefore not suitable for casting of particularly large-sized profiles.
- the invention has for its object to avoid the disadvantages mentioned above and to provide a cold strand packaging that ensures the full tightness of the cold strand packaging when casting even in very large formats.
- the invention further provides that the packaging plate is formed in two parts, wherein both plate halves are displaceable towards Kokillenmitte and separated by a distance to each other, whose width depends on the taper of the mold.
- the plate halves are drawn in the millimeter range within the distance. With appropriate dimensioning of the distance can be fully compensate in this way the oblique course of the mold.
- the distance is formed centrally. This makes it possible to form two plate halves identical.
- the cold strand head according to the invention has a one-piece packaging plate which covers both plate halves and which is clamped to the cold strand head.
- the plate halves are thus kept safe in terms of area by the one-piece packaging plate, without affecting their displaceability.
- the one-piece packaging plate is conveniently clamped to the cold rod head with tie rods attached thereto.
- the tie rods also serve in a known manner to absorb the tensile forces acting between the cold strand and the hot strand.
- the invention provides that the plate halves are provided with holes formed as elongated holes for the tie rods.
- the one-piece packaging plate according to the invention is provided with a longitudinally extending reinforcing rib, whereby its rigidity is improved, in particular in the web area.
- the in the FIGS. 1 to 8 cold strand head 1 shown is equipped with an inventive cold strands packaging 2. He is shown in the starting position before the casting process, in which he concludes the interior of a mold 3 for casting a large-sized beam blank double T-profile of about 800 mm wide, 400 mm flange width and 120 mm web thickness bottom. Above the cold strand head 1 there is at least one casting tube 4 projecting into the mold 3, through which molten steel is poured into the interior of the mold 3 during casting. Below the cold strand head 1, this is coupled to an extraction device 5, by means of which the strand is pulled out of the mold 3.
- the cold strand packaging 2 consists of a flat gasket 6 and two packaging plates 7 and 8, wherein the packaging plate 7 is divided into two symmetrically to each other in a plane plate halves 7a, 7b, between which a centrally arranged, continuous distance 9 of about 10 to 20 mm is present.
- the packaging plate 8 is formed in one piece and rectangular and covers the plate halves 7a, 7b in the web area.
- the packaging plates 7 and 8 are made of sheet steel with about 8-15 mm sheet thickness.
- the flat gasket 6 has the same outer contour as the inner contour of the mold, but with a circumferentially small excess of about 15 to 25 mm. It can be made of felt of about 6-12 mm thickness, but also of any other material with comparable properties, in particular mechanical strength, elasticity and heat resistance.
- the cold strand package 2 is mounted on the cold strand head 1 outside of the mold 3.
- the flat gasket 6 is clamped overhanging between the cold strand head 1 and the plate halves 7a, 7b.
- the protruding flat gasket bends around the outer edge of the plate halves 7a, 7b against the inner walls of the mold and seals the 4-8 mm wide gap between the packaging plates and mold around, so that no molten steel flows out during the gushing process.
- the one-piece packaging plate 8 is in turn pressed against the two plate halves 7a, 7b and has together with them the task to absorb the forces acting on the gasket 6 during insertion of the entire profile area including the web area.
- Tie rod 10, 11 in the form of bolts 12 which is used with the lower part 13 in the cold rod head 1 and locked with a cross bolt, and an upper threaded part 14, on which a nut 15 is screwed, are used to fasten the cold strand package 2 to the cold strand head 1.
- the plate halves 7a, 7b have slots 16 and 17 as through holes for the tie rods 10 and 11.
- the nuts 15 are screwed against Andschreibbüchsen 18, which in turn are pressed against the one-piece packaging plate 8.
- the tie rods 10 and 11 also take over the tensile forces that are effective between hot strand and cold strand when pulling out the strand.
- the one-piece packaging plate 8 is provided with a longitudinally extending reinforcing rib 23, that of the packaging plate 8 gives a higher rigidity in the middle range.
- the reinforcing rib 23 extends between the two tie rods 10 and 11.
- Fig. 7 shows the mold 3 in section along the line VII - VII according to Fig. 6 and schematically the cold strand package 2 in the position 2.1 before retraction, in the position 2.2 immediately after entering the mold 3 and additionally in the position 2.3 when reaching the lower end of the mold 3, as this also increases in Fig. 8 is illustrated.
- the flat gasket 6 protrudes laterally all the way to the packaging plate 7 located above it. As a result, it is angled evenly from the mold 3 as a tab 6 'and is thus between the adjusting packaging plate 7 and the mold and forms a secure seal all around.
- the adjustable packaging plate 7 In the downward displacement of the cold strand head 1 in the mold 3, the adjustable packaging plate 7 is always moved by the voltage applied to the mold flat gasket to Kokillenmitte. It is thus at least causes the sealing gap between it and the packaging plate 7 remains uniform.
- the packaging plate 7 In the position 2.2 immediately after the retraction of the cold strand package 2, the packaging plate 7 is pushed outward in relation to the shorter packaging plate 8, however, in the position 2.3, this packaging plate 7 is displaced comparatively more inwardly.
- the retractability of the packaging plate 7 it is also possible within the scope of the invention to provide other elements which are comparable in terms of effect, such as yielding plate regions or the like. It is also possible within the scope of the invention to form the distance 9 differently than uniformly, depending on the profile geometry, or to place it otherwise than centrally in the packaging plate.
