Definitions
- the invention relates to a distribution vessel for a Multi-strand caster for casting the same or different steel profiles, on each strand at least one outlet block is provided, which consists of a refractory perforated brick and one used in these fireproof nozzle block with an outlet opening. Furthermore, the invention relates to a discharge block for a metallurgical vessel, in particular a distribution vessel.
- distribution vessels are for casting of double-T profiles with a pair of discharge blocks provided, in a corresponding to the double-T profile Distance must be attached.
- the outlet blocks on the distribution vessel both in their Longitudinal alignment as well as in their transverse alignment be set accordingly, so that according to the status of Technology arranged concentrically on the outlet block Outlet opening of the nozzle block in the center line of the Profile stands.
- the object of the invention is a distribution vessel or a Design the outlet block so that the setting on Different profiles can be carried out quickly and easily is.
- the above object is for a distributor vessel of the type mentioned in that the Nozzle stone has a rotationally symmetrical circumferential surface has that in a correspondingly rotationally symmetrical Recess of the perforated brick in different angles of rotation can be used, and that the outlet opening of the nozzle block eccentric to the axis of rotation of the rotationally symmetrical Circumferential surface.
- perforated block of the outlet block can instead of Insert an immersion nozzle when pouring not open, but closed.
- a discharge block according to the invention is characterized by this from that the nozzle stone is a rotationally symmetrical Has circumferential surface, which in a corresponding rotationally symmetrical recess of the perforated brick in different angles of rotation can be used and that the Outflow opening of the nozzle block eccentrically to Rotation axis of the rotationally symmetrical peripheral surface lies.
- FIGS. 5, 7 and 9 are those to be cast in each case Double-T profiles are shown in dashed lines for clarity.
- a tundish (1) points for casting three Strands three recesses (2,3,4).
- the recesses (2,3,4) is a pair of runout blocks (5) used.
- Each outlet block (5) consists of a perforated brick (6) and a nozzle block (7) inserted in this.
- the perforated stone (6) has a rectangular, preferably square Outer contour on (see. Fig. 4).
- the nozzle block (7) is with a rotationally symmetrical, especially circular, Provided peripheral surface (8) in a corresponding rotationally symmetrical recess (9) of the perforated brick (6) fits.
- the peripheral surface (8) and the recess (9) are designed conical (see. Fig. 3).
- the nozzle block (7) has an outlet opening (10) provided, which is eccentric to the axis of rotation (A) of the rotationally symmetrical peripheral surface (8).
- a mouthpiece (11) is arranged in the outlet opening (10).
- At the Nozzle block (7) can also have a replacement outlet opening (10 ') can be provided when the former wear Outlet opening (10) can be put into operation.
- the replacement outlet opening (10 ') is expediently arranged diametrically to the outlet opening (10).
- the outlet opening is located (10) on the center line (M) of the outlet block (5).
- the 6 has the outlet opening (10) a distance (a) from the center line (M).
- the 8 is the outlet opening (10) in a distance (b) to the center line (M).
- the center line (M) of the discharge block (5) is in each case Longitudinal direction of the recesses (2,3,4).
- the recesses (2,3,4) are each longer than the total length of two Outlet blocks (5) in the direction of the center line (M).
- Which when installing the outlet blocks (5) in the recesses (2,3 or 4) resulting gaps are with fitting plates (13) filled out.
- the fitting plates (13) are on the distribution vessel (1) held by support elements (14) from below (see Fig. 1).
- the outlet blocks (5) fit into the Recesses (2, 3 or 4).
- appropriate guidance can help be provided or the rectangular perforated brick (6) deviate from the square basic shape.
- the profile (P1) be poured. Its ideal center line (m1) or the The center line of the associated mold coincides with the Center line (M) of the outlet block (5) together. That's why are two outlet blocks (5) with setting the 4 on the marking "0" used, the nozzle block of the right discharge block is set to the left mark "0" in FIG. 4.
- the profile (P2) should be poured. Its ideal center line (m2) deviates from the center line (M) of the discharge block (5) around the width (a) from. So that the outlet openings (10) on the ideal Center line (m2), two outlet blocks (5) used, in which the nozzle stones (7) in the 6, the nozzle block the left discharge block at the upper right marking "25” and the nozzle block of the right discharge block at the upper left marking "25” stands.
- a double T profile is intended (P3) can be poured.
- Its ideal center line (m3) lies around the width (b) next to the center line (M) of the Outlet blocks (5).
- FIGS. 5, 7, 9 are shown in FIG. 1 and 2 shown in the recesses (2,3 and 4).
- the Distribution vessel (1) can thus be three different ones Cast double T profiles. Should be on one or the other Place a different profile of the distribution vessel (1), for example a profile for which an outlet block (5) is enough to be poured, then will be in the appropriate Recess (2, 3 or 4) with only one outlet block (5) corresponding angular position of its nozzle block (7) used. The remaining space is with Fitting plates (13) closed.
- Distribution vessel (1) in the area of the outlet blocks (5) and Fitting plates (13) with a continuous lining layer (15).
