Definitions

  • the invention relates to a refractory ceramic baffle pot.
  • a generic baffle is known for example from the following publications: DE 102 35 867 B3 . DE 102 02 537 C1 . US 5,358,551 . US 2004/0070123 A1 ,
  • the baffle according to US 5,358,551 has a classic pot shape, in which the upper free end portion of the wall is deflected inwards.
  • the molten metal after striking the bottom of the baffle, first flows along the bottom, then upwardly along the inside of the wall, and finally around the tapered baffle opening, up into the tundish.
  • the baffle is formed at its upper open end with a so-called diffuser, that is, the cross section of the baffle becomes larger towards the upper outlet end to reduce the kinetic energy of the outflowing melt.
  • the proposal according to DE 102 02 537 C1 provides a baffle whose wall has at least one slot extending continuously from the edge (the upper free end of the wall) to the bottom, the slot width at the widest point being less than 10% of the widthwise dimension of the Floor plan should be.
  • the baffle according to US 2004/0070123 A1 has an inwardly broadened, protruded upper edge to redirect the flow of molten metal.
  • baffles have a circular or rectangular base. Accordingly, the wall is endless or it consists of four wall sections.
  • the base (the floor plan) may also be different, for example, oval or egg-shaped. According to the invention, it is particularly assumed that baffle pots are formed with mirror image (mirror-symmetrical) with respect to a vertical plane.
  • the following information relates in each case to a normal functional position of the baffle (functional position), in which the bottom of the baffle is on or in a bottom of a metallurgical vessel and the wall of the baffle substantially perpendicular to the ground and thus substantially perpendicular from the bottom of the metallurgical Vessel extends upwards.
  • the baffle according to DE 102 02 537 C1 causes molten metal that enters the baffle, at least partially flows laterally through the wall-side slot. Due to the relatively small slot width, the melt flowing through the slot can have a considerable flow velocity. This causes additional flow turbulence.
  • the essay " Melt Flow Characterization in Continuous Casting Tundishes "(ISIJ International, Vol. 36 (1996), No. 6, pp. 667-672) ) defines a so-called plug flow, in which all fluid elements have the same residence time (residence time) in the tundish and a so-called dead volume.
  • the dead volume characterizes the proportion of fluid whose residence time is more than twice the average residence time of the melt in the tundish.
  • the flow direction is substantially horizontal or at an angle ⁇ 70 °, in particular ⁇ 45 ° to the horizontal. It has also been found to be favorable to make the baffle so that the laterally exiting flow widens upwards (toward the free upper end portion of the baffle).
  • the baffle wall has at least one opening (for example a slot) with a specific cross-sectional profile.
  • the width of the opening increases (in the circumferential direction of the baffle), that is, in the case of a slit-shaped opening, the spacing of the flanks laterally delimits the slot.
  • baffle - As known - upwards.
  • openings with a relatively large cross-section in the wall region of the baffle means that less refractory material must be used. This reduces the manufacturing costs.
  • the invention relates to a refractory ceramic baffle with the features of the main claim.
  • the opening can pass upwards, so that the free end of the wall is interrupted. However, the opening can also run as a discrete opening in the wall and be surrounded on all sides by wall sections.
  • cross-sectional profiles are preferred, which are mirror-symmetrical to a plane that projects perpendicularly from the inside of the wall, in other words: the plane of symmetry extends radially in a baffle with a circular floor plan (bottom), whose wall is a cylindrical peripheral surface having.
  • the flow is optimized when the opening has curved flanks, in particular between the sections of greatest width and smallest width. In the side view, this results in a profile of the opening similar to a funnel or a nozzle.
  • the opening in the region between the largest width and the smallest width with respect to a central longitudinal axis of the opening has convexly or concavely curved flanks. This means that the width of the opening decreases steadily between the sections of greatest width and smallest width.
  • the opening ends according to one embodiment at a distance from the ground. It follows that within the baffle a bottom sump is formed, in which there is regularly molten metal during the casting process.
  • the opening extends over more than 50% of the height of the wall.
  • the flow pattern is optimized when the opening extends over a greater part of the height of the wall, for example more than 60% or more than 70%.
  • the area of the baffle wall without lateral opening can be at least 20% of the height of the wall, calculated from the ground. This corresponds to a maximum extension of the opening over 80% of the height of the wall, calculated from its upper end.
  • an embodiment of the invention provides for forming the inside of the wall, between the baffle surface of the base and the opening, with an inclination ⁇ 90 ° to the horizontal.
  • the result is a kind of "ramp" along which the melt, after being hit on the baffle, is led away not only laterally, but laterally upwards, specifically to the corresponding opening.
  • This embodiment is also shown in more detail in the following description of the figures.
  • the latter embodiment requires that the opening ends at a distance from the bottom of the baffle pot.
  • the opening can also extend from the free end to the floor. This corresponds in principle to the embodiment according to FIG DE 102 02 537 C1 .
  • the crucial difference to the known baffle is that the slot (the opening) in the wall of the baffle pot according to the invention is significantly larger and is characterized in particular by the fact that the cross section of the opening in the direction of the upper edge (the free edge) of Wall significantly enlarged.
  • the largest width of the opening is according to the invention more than 5% of the total circumference of the wall of the baffle pot. For a baffle with square base and corresponding four equal wall sections, this means that the largest width of the opening is more than 20% of the width of the corresponding wall section. This value also applies according to the invention for baffles with a rectangular plan, with the proviso that the value of the opening width refers to each of the wall portion in which the opening is located.
  • the greatest width of the opening is more than 5% of the total circumference of the wall of the baffle. Dividing the wall into four equal sections, the value for the largest width of the opening, relative to each section, is again more than 20%.
  • the maximum width of the opening must be more than 20% of a quarter of the total circumference of the wall.
  • the largest width is meaningfully limited to 25% of the total circumference of the baffle wall.
  • the smallest width of the opening (at the end of the opening / slot adjacent to the baffle bottom) is, for example, ⁇ 4%, ⁇ 2.5%, ⁇ 1.5%, ⁇ 1.0% of the total perimeter of the wall, and may also be, for example, with a V-shape of the slot, go to zero.
  • the maximum value makes sense a maximum of 5%.
  • corresponding flanks of the opening are arranged between an inner side of the wall and a corresponding outer side of the wall with increasing distance.
  • flanks may be bowed to the outside environment, thereby assisting the effect.
  • the baffle according to FIG. 1 is constructed as follows: It has a rectangular bottom 10 with a lower base 10g and an upper baffle 10p. From the edge region of the bottom 10 extends a wall 20, which accordingly comprises four wall sections 20a, 20b, 20c and 20d.
  • the free end 20k of the wall sections 20a to 20d is drawn inwardly, so that a corresponding undercut 20h results between the vertical regions of the wall sections 20a to 20d and the free end 20k (end section).
  • an opening 40 is formed, which extends from the free end 20k to over half the height H of the wall portion 20a.
  • the vertical height h of the opening 40 corresponds to about 0.6 H.
  • the opening has its greatest width Bg at its upper end and its smallest width Bk at the lower end.
  • the flanks 40f of the opening 40 are mirror-inverted relative to each other with respect to a central longitudinal axis M-M of the opening 40, resulting in a continuously decreasing cross-sectional geometry from the upper end to the lower end of the opening.
  • the flanks 40f extend 90 ° to the inner side 20i of the wall 20.
  • the largest width Bg of the opening 40 is about 35% of the mean length L of the associated wall portion 20a and accordingly about 9% of the total circumference of the wall 20.
  • the molten metal flowing into the baffle pot (indicated schematically by the arrow S) strikes the baffle surface first 10p and then spreads along the baffle 10p before going up along the inner side 20i of the wall 20. While the melt in the region of the wall sections 20b, 20c and 20d is subsequently deflected in the region of the undercut-formed free end 20k and led out of the baffle upwards (the same applies to the melt which flows along the wall 20a adjacent to the opening 40) , The flow rate is reduced analogously with increasing width of the opening 40.
  • the flow direction is at the narrow end of the opening 40 largely horizontal, obliquely directed upward at the upper, wide end. In this way, an advantageous supply of the melt from the impact pot in the associated metallurgical vessel or in the melt located there.
  • FIG. 2 shows some possible cross-sectional shapes of the wall opening 40.
  • Number 1 is similar to the example in FIG. 1 formed, but the opening passes down to the bottom area.
  • Variation No. 2 approximates the cross-sectional profile of a funnel.
  • the flanks of the opening are bowl-shaped.
  • the opening according to No. 4 is completely formed in the wall 20 and otherwise corresponds to the upper part according to No. 2.
  • the flanks are not curved, but designed step-like.
  • the cross-sectional geometry according to No. 6 is similar to that of a calyx.
  • the embodiment according to FIG. 3 differs from the according to FIG. 1 in that the opening 40 extends to the bottom 10, that is to say to the baffle surface 10p, and is formed in its lower portion in the manner of a slot with a constant width Bk.
  • Another difference to the embodiment according to FIG. 1 is that the flanks 40f open to the outside 20s of the wall 20a, whereby an additional diffuser effect is achieved in the outflow of molten metal from the baffle.
  • an essential difference to the other illustrated embodiments is that the inner side 20i of the wall 20a at an angle a of about 45 ° (to the horizontal) of the baffle surface 10p in the direction of the opening 40 increases, creating a kind of ramp for the molten metal is formed towards the opening 40.
  • the opening 40 ends, as the side view shows, similar to the embodiment according to FIG. 1 at a distance from the baffle 10p and points, similar to at FIG. 3 , a diffuser area on.
  • the baffle consists of a refractory ceramic material, for example based on magnesia, magnesia chromite, bauxite, A1 2 O 3 or mixtures thereof.
  • baffle pots in which the upper free end portion of the wall (wall parts) is widened inwardly, so that the upward emerging from the baffle melt is redirected to the inside.
  • baffle pot The base of the baffle pot is virtually arbitrary. Impact pots with a circular bottom and cylindrical wall and baffle pots with rectangular, in particular square bottom and corresponding four, at right angles to each other extending wall sections are clearly preferred in terms of production and flow behavior.
  • each baffle at least one opening of the type described is formed on the wall side.
  • analogous openings can be formed in opposite wall sections.
  • Each aperture is significantly narrower in its portion adjacent the bottom than at its portion adjacent to the top edge (the upper edge) of the baffle wall. This results regularly in the side view, a cross-sectional profile, in which the width of the opening decreases from top to bottom. Only then can the desired volume flow be led away laterally and achieve the desired distribution of the flow velocity.
  • the opening is wider from bottom to top and has a lower flow rate than at the bottom.
  • the flow direction can be adjusted by appropriate design of the flanks of the opening, in particular in the sense to guide the flow so that the cross-section of the volume flow increases with increasing distance from the baffle.
