Definitions
- the invention relates to a distributor for continuous casting plants according to the preamble of claim 1.
- the steel continuous casting is a well known method for continu ous ⁇ casting of steel slabs.
- steel is usually produced in a converter, transferred from the steel converter in a pan and forwarded by the pan via a distributor to the casting mold.
- the distributor has the task here, after emptying a pan and feeding the next pan, to ensure a continuous flow of steel.
- This continuous casting plant has a ladle holding and changing device (ladle turret), ladles and a distributor trough and a continuous casting mold and a Strangab ⁇ zugsvorraum.
- the in preparation for transport in the pouring position filled with melt ladle is associated with a distributing trough for common transport with the ⁇ ser.
- the distributor trough is inserted into the jib for the reception of the ladle vorgese ⁇ Henen boom on the ladle tower below the ladle.
- Tundish and / or ladle are provided with ⁇ With stuffs for releasable connection with each other.
- EP 0 140 217 A1 discloses a method and a device for changing the ladle and intermediate container at a continuous casting plant.
- EP 0 804 306 B1 discloses an apparatus for controlling the flow of molten metal in a distributor trough to improve the separation of inclusions from the metal bath.
- a flow control dam is downstream ⁇ Windier positioned by a shock buffer, which has an upper portion which is adapted to receive a flow of molten steel, which disengages from the impact pad, and at least one secondary stream flowing in a downstream direction toward the slag cover , And in at least one Crow ⁇ stream, which flows in an upstream direction to the slag can divert.
- a shock buffer which has an upper portion which is adapted to receive a flow of molten steel, which disengages from the impact pad, and at least one secondary stream flowing in a downstream direction toward the slag cover , And in at least one Mau ⁇ stream, which flows in an upstream direction to the slag can divert.
- it is a built-in dam to prevent a short circuit flow.
- the invention is intended to reduce the amount of residual steel in the distributor, to increase the output and to maintain the particle separation behavior of the distributor to at least the existing extent.
- short-circuit currents are to be avoided in which the molten steel from the ladle on the ladle shroud directly, that flows manifold outlet by the shortest route, near the bottom of the distributor in Rich ⁇ processing and passes through the casting tube in the co ⁇ kille. Particles in this short-circuit flow can not be deposited in the distributor on the bath mirror surface of the distributor and get in this way with the molten steel directly into the mold, which must be avoided at all costs.
- openings which are provided in the direction of the distributor outlet, and in particular channels which are open at the top, are formed starting from the two lateral longitudinal boundaries (longitudinal walls) of the distributor in the direction of the longitudinal axis of the distributor and extend in particular to the bottom of the pot.
- these recesses are designed symmetrically to the longitudinal axis of the distributor.
- lateral channels or at least one mallli ⁇ cher channel are formed.
- an IMP EXP ⁇ including flow-through cross-sectional area which is between 10% and 30%, preferably between 15% and 25%, the cross-sectional area of the Pot lies.
- the area of the wall or the installation is preferably less than 50% of the total area, more preferably less than 40%.
- the channel or the channels can slightly from the respective side wall, ie, be from 0.01% to 25% of the width of the distri ⁇ lerinnenraums spaced.
- the invention is exemplified with reference to a drawing erläu ⁇ tert. It shows:
- FIG. 3 a distributor according to the invention in a highly schematic view from above;
- Figure 4 the distributor of Figure 3 in a side sectional view ..;
- FIG. 5 shows the results of numerical CFD calculations (RTD curves).
- FIG. 6 shows the distributor according to the invention in a highly schematic isometric, partially transparent view
- FIG. 7 shows the cross section through a channel according to the invention in the bottom of the distributor
- Figure 8 the flow profile at the inlet of steel in the
- FIG. 9 shows the flow profile when introducing steel into the distributor according to the invention.
- An inventive distributor 1 is an elongated, trogen-like container with two opposite Stirnwan ⁇ tions 2, 3 and two connecting the end walls side walls 4, 5 (Fig. 1 and Fig. 2).
- the bottom 6 of the manifold 1 can deepen from a Einlaufbe ⁇ rich 7 to an outlet portion 8 obliquely, said obliquely means here that the depth becomes deeper toward ⁇ over a mirror 10th
- the distributor base 6 can thereby lower from an upper edge 12a of the threshold 12 with an elongated inclination 14 in the direction of the distributor outlet 8.
- the bottom 6 in the region of the inlet region 7 and the outlet region 8 with respect to a bathroom mirror 10 is flat.
- the maximum bath level 10 in the operation of the distributor 1 is meant. When emptying the distributor 1 the Badspie ⁇ gel drops from the maximum level of the bath 10 during operation.
- the edge of the pot 13 or the threshold 12 or ramp 12 is formed at least along ei ⁇ ner side wall 4, 5 in the direction of the distributor outlet 8 with a channel-like opening 15 which extends from the upper edge 12a of the tie 12 or ramp 12, preferably ranging up to a level of the bottom 6 in the region of the a ⁇ running region. 7
- the channels 15 are thus bounded on the one hand by its channel bottom 16, on the other hand by a side wall 4, 5 and a channel wall 17 of the threshold 12 or ramp 12.
- the channels 15 may also be slightly spaced from the side walls 4, 5, so that the threshold 12 is not broken edge-side but a small piece to the longitudinal axis 9 is broken.
- the channel 15 or the channels 15 have in a conventional distribution geometry, for example, a width of 70 mm to 80 mm, a height corresponding to the height of the threshold 12, where ⁇ it has been found to be advantageous if the channels 15 limiting walls 4, 5 and 17, respectively, from the channel floor diverging wegdivergierend, for example, at an angle of 10 ° to 20 ° (Fig. 6 and Fig. 7).
- the threshold 12 or ramp 12 can be arranged perpendicular to the longitudinal axis 9 of the distributor 1, it can also be rounded or curved.
- the threshold 12 has a height which is less than the maximum bath level 10 in the operation of the distributor 1, so as not to negatively influence the particle flow.
- the threshold 12 preferably has a height in the ratio of less than 1: 5, particularly preferably less than 1:10, in comparison to the bath level 10.
