Definitions

  • the invention relates to a method for continuous or semi-continuous continuous casting, in particular in a vertical casting plant for casting steel, in which the strand is lowered in a cooled mold at the end of casting after the melt supply has been stopped.
  • Such vertical casting systems are known to be used for the production of relatively short strands with larger cross-sectional formats.
  • molten metal is fed from a metallurgical vessel, such as from a pan or an intermediate container, through a pouring pipe into a water-cooled mold, for example made of copper material.
  • the strand that forms in it is poured vertically downwards until it has reached a defined length.
  • the output of these relatively short strands is achieved by reducing the volume of the cast Materials, especially steel, determined during solidification. This volume reduction leads to the fact that, without suitable countermeasures, a funnel is formed at the upper end of the solidified strand. In order to reduce or even prevent this funnel and thereby to increase the output of the continuously or semi-continuously cast strands, various methods are proposed.
  • a method in such a vertical casting installation is according to the publication WO-A-2015/101 553 known, in which after the end of the regular casting process, liquid metal is supplied to a certain extent.
  • a heating device positioned around the upper end region of the strand can be provided which controls the liquid metal reservoir at the top in the interior of the strand. At least the shrinkage of the metal melt that occurs during solidification can thus be compensated for and the resulting shrinkage cavity in the upper strand area can be shortened.
  • the invention is based on the object of largely eliminating these disadvantages and creating a method of the type mentioned above, which is characterized by simple handling in the continuous or semi-continuous casting of relatively short, large-sized strands and a higher output rate of the usable strand due to lower shrinkage cavities and consequently also enables cost savings.
  • the system according to the invention has the advantage that only one dipping of the pipe element into the mold and, if necessary, an addition of insulating casting or covering powder over the molten metal is necessary after the end of the casting process. This simple procedure enables better output rates due to the shorter upper strand end that has to be cut away.
  • the invention provides that the external dimensions of the tubular element are smaller than the internal dimensions of the mold, the gap formed between them being dimensioned accordingly that the gap dimension is, for example, approximately the thickness of the strand shell formed in the mold in the normal casting process corresponds to or is chosen to be smaller.
  • the melt located in this gap solidifies at a solidification rate predetermined by the mold cooling.
  • a connection between the outer strand shell and the pipe material can simultaneously serve as a holding element for the pipe element, while inside the pipe element the solidification process of the molten metal continues at a greatly reduced solidification rate due to the insulating effect of the pipe element.
  • the strand which is still liquid at the top, is lowered in the mold so that the melt displaced to the outside of the tubular element after the insertion of the pipe element does not flow over the mold, but rises to approximately the same level as when it was poured.
  • the outer contour of the tubular element is adapted to the inner contour of the mold in such a way that the gap formed between them is dimensioned uniformly over the entire circumference.
  • tubular element has a wall thickness that is uniform over its entire length.
  • an inwardly protruding ring attachment can be assigned to its lower end.
  • pipe element can also be advantageous for the pipe element to be assembled from different pipe segments in order, for example, to build up modularly pipe elements for different casting formats from segment parts.
  • Fig. 1 shows schematically the mold area with a mold 1 of a vertical casting plant 10, which is used by continuous or semi-continuous continuous casting to produce, in particular, short, large-format strands.
  • a strand 5 which runs vertically downward from the mold 1 is produced, which is supported from below and can have a length of, for example, a few meters to 20 meters.
  • Conventional cooling zones for the solidification of the strand are arranged below the mold, but these are not illustrated in more detail.
  • FIG. 3a shows the mold 1 during the pouring of molten steel through a pouring pipe 13 made of a metallurgical not shown in detail Vessel, for example from a pan or from a distributor serving as an intermediate container.
  • the molten steel is poured in in a conventional manner at a given fill level 15 at the upper end of the mold by an adjustable closure element such as a stopper or a slide closure, and the strand 5 is correspondingly lowered from the mold at a withdrawal speed.
  • the vessel with the pouring pipe 13 is removed and, as in FIG Figure 3b is illustrated, the strand 5 and thus the level 15 'in the mold is lowered. However, before the level 15 'has reached the lower end of the mold 1, the strand is stopped.
  • a tubular element 2 for example with a weight 19, is inserted into the mold 1 by means of a manipulator (not shown in detail).
  • a manipulator not shown in detail.
  • fastening or coupling means are provided in the form of, for example, retractable and extractable bolts 9 or the like, which engage releasably into corresponding bores in the tubular element.
  • this tubular element 2 is dipped according to the invention with its lower end 2 'into the molten metal in the mold 1 in such a way that the fill level of the molten metal rises almost to the upper end of the mold 1, as during casting.
  • the pipe element 2 is optionally weighted by means of the weight 19, and a liquid metal reservoir 12 is formed in this pipe element, which can be covered at the top with a heat-insulating material, preferably covering powder 11.
  • the tubular element 2 is made as a sleeve-shaped body made of refractory material, the dimensions of which are narrower than the internal dimensions of the mold 1.
  • a gap 7 is formed over the entire circumference of the mold 1, which is dimensioned so that the pipe element 2 is located within a strand shell 5 'that forms in the mold during casting, while inside the pipe element the solidification process of the steel melt due to the insulating Effect of the pipe element is continued with a strongly reduced solidification rate compared to the conditions outside the pipe element.
  • the outer contour of the tubular element 2 is adapted to the inner contour of the mold 1 in such a way that the gap 7 between them is dimensioned with a uniform thickness d over the entire circumference.
  • the melt displaced when the tube element is immersed into the gap forms an optimal retaining ring for the tube element after it has solidified, which ring also has a uniform wall thickness.
  • This gap 7 formed is advantageously dimensioned approximately between 1 and 10% of the internal dimensions of the mold 1, so that an optimal state can be achieved by this retaining ring encompassing the tubular element.
  • the mold and the tubular element are rectangular in cross section. But you could of course also be designed differently, such as round, square, polygonal or other format.
  • the tubular element 2 is immersed in the mold 1 after the melt supply has ended by such a length as from Figure 3c it can be seen that its lower end 2 'is approximately the forming depth 14 of the shrinkage funnel 12 at the upper end of the strand after the strand 5 and the melt within the tubular element have solidified is equivalent to.
  • the melt volume located inside the pipe element compensates for the volume shrinkage due to the solidification of the strand located below the pipe element, whereby it must be ensured that the not yet solidified melt from the inner pipe volume into the lower strand can flow.
  • the pipe element 2 is preferably dimensioned with its wall thickness such that it has such a submerged volume in the submerged state at the defined depth that the fill level 15 of the molten metal results almost to the upper end of the mold, as during casting.
  • this tubular element 2 has such a length that it can protrude beyond the mold 1 at the opposite upper end in the state in the defined submerged depth. At its upper end, it is advantageously loaded with a weight 19, which prevents the lighter refractory material of the pipe element from floating in the melt and can also serve as a connecting means with the pipe element for coupling to the manipulator or a crane. It can thus be brought in from this via the mold and can then be dipped into it.
  • this heat-insulating material preferably covering powder 11, can be filled onto the molten metal 12 in this protruding area of the tubular element.
  • FIG. 11 shows a variant of a tubular element 22 in FIG Figure 3c explained casting phase. It differs from the tubular element 2 only in that an inwardly protruding ring shoulder 18 is assigned to its lower end.
  • Fig. 5 shows a pipe element 24 composed of several pipe segments 25, 26 in the mold 1 in cross section.
  • the outer contour of the tubular element 24 is in turn adapted to the inner contour of the mold 1 in such a way that a uniformly thick gap 7 is present between them over the entire circumference.
  • These pipe segments 25, 26 are, for example, flat-walled or corner-shaped, as shown, and are advantageously mortared to one another. Depending on the size, more or fewer such pipe segments could also be used.
  • this ceramic tube element could already be immersed in the melt after the melt supply has been stopped while the strand is being lowered in the mold. This would only lower the level slightly.
  • the outer and / or inner shape of the ceramic tube element could be provided with a taper in cross section in the casting direction.
  • the tapering of the outer shape could be selected so that it is adapted to the solidified strand shell, which increases in the pouring direction. In this way, the space between the pipe element and the inner shape of the strand could be optimized.
  • the tubular element could theoretically also be made of metal, for example steel, or partly of ceramic material and partly of steel be made.
  • a design partially made of steel advantageously on the outside of the pipe element allows the pipe element to fuse with the melt in the gap 7 between the pipe element and the mold, which, due to the solidification caused by the mold cooling, leads to a firm connection between the pipe element and the outer strand shell in the gap 7 so that the weight 19 can be removed at a very early stage after the casting is finished.
  • the tubular element could also be pushed into the mold without this gap 7 and thereby have approximately the internal dimensions of the mold.
  • the heat-insulating effect of the pipe element in connection with the possible task of the insulating powder is advantageously chosen so that, despite slowly progressing solidification within the pipe element, a liquid reservoir is kept for so long that the volume shrinkage in the strand located below the pipe element due to the faster solidification there than can be approximately or completely compensated for in the melt located within the pipe element.
