Definitions

  • the invention relates to a closing and / or regulating element for an elongated spout of a container containing molten metal, with a refractory, tubular, immovable closure part and a refractory, tubular closure part rotatable relative to this in a metal-tight manner, the one closure part being mounted in the other closure part and both closure parts are each provided with an outlet opening designed as a longitudinal slot.
  • Inlet parts are provided on the closure parts which, like the outlet openings, are slit-shaped and diametrically opposite the outlet openings with respect to the common longitudinal axis of the two tubular closure parts.
  • the melt flows radially through the cavity of the internal closure part.
  • the cavity does not contribute to the distribution of the melt over the slot-shaped outlet openings.
  • the longitudinal slots weaken the closure parts, since each closure part is provided with two longitudinal slots.
  • DE 38 09 071 A1 describes a twist lock in which radial and diametrical breakthroughs of the movable closure part are avoided.
  • a recess in the outer surface of this closure part forms the connecting channel between the inlet opening and the outlet opening.
  • the outer, tubular closure part is weakened by two slots.
  • the cavity of the tubular inner closure part does not support to distribute the melt to the outlet opening.
  • the recess is exposed to the sealing surface of the outer closure part, so that it is exposed to wear from the melt.
  • Another control device for a slit-shaped spout is described in DE 35 08 218 A1.
  • the melt flow rate can be adjusted there by thermal influence on its viscosity.
  • a shut-off device is not shown.
  • CH 671 716 A5 describes a device for casting thin strips or foils made of metallic material.
  • a longitudinal slot is provided in a tubular nozzle body. One end of the nozzle body is closed. The melt flows in at the other end.
  • the level of the melt in the vessel can be regulated, or the melt is pressurized, the nozzle body being arranged above the melt level.
  • the nozzle body does not form a closing and / or regulating element.
  • the object of the invention is to propose a closing and / or regulating member of the type mentioned, in which it is avoided that the melt radially through to the longitudinal axis of the tubular closure parts the internal cavity flows to the outlet openings and in which the stability of the tubular closure parts is improved.
  • the above object is achieved in a closing and / or regulating member of the type mentioned at the outset in that the cavity of the inner, tubular closure part is closed on one end face and is open on the other end face and forms an inlet opening thereon which extends over the cavity of the inner closure part is connected to its slit-shaped outlet opening, a flow zone being formed in the cavity on the one hand between the inlet opening and the slit-shaped outlet opening of the inner closure part and, on the other hand, a storage space between the above-mentioned outlet opening and the closed end face.
  • the melt enters the cavity on the face side. There is therefore no need for an inlet slot parallel to the slot-shaped outlet opening on the inner, tubular closure part. Likewise, an inlet slot extending parallel to the slot-shaped outlet opening on the outer tubular closure part is superfluous.
  • the stability of the two closure parts is considerably improved. This is particularly important because the two closure parts, which are mounted one inside the other, must be able to be easily rotated about their common longitudinal axis in order to ensure the desired closing and / or control function. It is thus achieved that the thickness of the melt strip leaving the slit-shaped outlet opening of the outer closure part can be sensitively controlled by rotating the two outlet openings and, if necessary, the melt outlet can be interrupted. The width of the melt strip flowing out can be control by moving the closure parts in the direction of the longitudinal axis.
  • the molten metal does not enter the cavity diametrically or radially, but rather flows into it in the longitudinal direction, because the flow zone aligns the inflowing molten metal in the direction of the closed end face.
  • the cavity forms a buffer which ensures that the melt is under the same pressure practically over the entire length of the slot-shaped outlet openings. It is achieved in that the emerging melt strip leads to metal strips or sheets of uniform thickness, the uniformity of the thickness also existing in the edge regions.
  • the closing and / or regulating element described is therefore suitable for continuous casting close to the final dimensions, in particular strip casting, or thin slab casting, with the otherwise necessary rolling operations being eliminated. Due to the controllability of the emerging melt belt, the need to control the speed of a cooling drum or cooling belt which takes over the melt belt and is arranged downstream of the closing and / or regulating member takes a back seat.
  • melt present in the cavity can also be in direct connection with the melt in the vessel when the closing member is closed, since this counteracts blockage of the cavity. It is also advantageous that the closure parts can be pulled off and replaced in the axial direction when worn.
  • a plant for casting sheet metal or thin strips has a container (2) containing molten metal (1).
  • a closing and / or regulating element (3) is arranged at the bottom of this at an outlet (4).
  • a cooling roller (5) or a cooling belt is arranged downstream of the closing and / or regulating element (3) in the melt outflow direction. The melt strip emerging from the closing and / or regulating member (3) is drawn off from the cooling roll (5) or the cooling belt.
  • the closing and / or regulating member (3) has an immovable closure part (6) fastened to the container (2).
  • This is tubular and consists of a refractory, ceramic material.
  • the closing and / or regulating member (3) has a movable closure part (7).
  • This is also tubular and consists of a refractory, ceramic material.
  • the closure part (7) is rotatable relative to the closure part (6) about the common longitudinal axis (L). It can also be axially displaceable in the direction of the longitudinal axis (L).
  • the immovable closure part (6) has a longitudinal slot (8) as an outlet opening.
  • the closure part (7) is provided with a longitudinal slot (9) as an outlet opening.
  • Both longitudinal slots (8,9) have the same length (A) and the same width (B).
  • the longitudinal slots (8, 9) together form the melt strip emerging on the cooling roll (5).
  • the closing and / or regulating element (3) is arranged at the bottom, laterally outside the container (2).
  • the closing and / or regulating member (3) is arranged at the bottom inside the container (2), so that it requires a longitudinal slot (10) which continues the longitudinal slots (8, 9) and which the cooling roller ( 5) is subordinate.
  • the closing and / or regulating member (3) is arranged below the container (2).
  • the closure part (7 or 6) lying inside the outer closure part (6, 7) forms an internal cylindrical cavity (11). This is closed on one end (12). There is a storage space (13) between the closed end face (12) and the end of the longitudinal slot (8, 9) near it. If necessary, this can have a vent hole. Opposite the closed end face (12) in the direction of the longitudinal axis (L), an inlet opening (14) is formed on the inner closure part (6, 7). Between the inlet opening (14) and the end of the longitudinal slot (8 or 9) close to it, the cavity (11) forms a flow zone (15) which directs the melt flowing in through the inlet opening (14) towards the closed end face (12). aligns.
  • the movable closure part (7) has an extension (16) which is guided outwards.
  • a control element (not shown in more detail) engages the extension (16), with which the closure part (7) can be rotated in the direction (D) about the longitudinal axis (L) and, if appropriate, can also be displaced axially to the longitudinal axis (L) in the direction of the arrow (E) is.
  • the movable closure member (7) is the internal closure member. Accordingly, the external closure part (6) is on a side connection (17) of the container (2) by means of a flange (18) attached. Since the outer closure part (6) is fixed in this embodiment, its longitudinal slot (8) is firmly assigned to the cooling roller (5).
  • the closure part (6) which is fixed to the socket (17) by means of its flange (18), is the inside closure part.
  • the outer closure part (7) is movable.
  • the closure part (6) attached to the container (2) is the external closure part. It is inside the container (2).
  • the movable closure part (7) is arranged inside the closure part (6).
  • the outer closure part (6 or 7) is in each case open on the end face in which the open end face or the inlet opening (14) of the inner closure part lies.
  • the outer closure part (6 or 7) does not interfere with the flow of the melt into the inlet opening (14) of the inner closure part (6 or 7).
  • support webs (19) can be provided in the container (2).
  • the inlet opening (14) of the internal, movable closure part (7) is formed by an edge (20) which is inclined to the longitudinal axis (L).
  • the edge delimiting the inlet opening (14) runs perpendicular to the longitudinal axis (L).
  • the external, fixed closure part (6) arranged inside the container (2) has an inlet opening (21) corresponding to the inlet opening (14) delimited by the edge (20). This lies radially to the longitudinal axis (L). However, it does not face the longitudinal slots (8.9).
  • the flow zone (15) exists between it and the end of the longitudinal slots (8, 9) near it.
  • the inlet opening (21) allows the outer closure part (6) to be supported on the container (2) also at its end close to the inlet opening (21). This improves the stability of the arrangement.
  • the edge (20) could also be stepped.
  • the closing and / or regulating member (3) is arranged below the container (2) at its outlet (4).
  • the internal, movable closure part (7) has the inlet opening (14) described in FIG. 7 with the inclined edge (20).
  • the outlet (4) opens into the inlet opening (21).
  • the static pressure of the melt in the closing and / or regulating member (3) is increased compared to the embodiment according to FIG. 1 or 5. This can improve the even pressure distribution over the length (A) of the longitudinal slots (8,9).
  • a spatially more compact structure is achieved than in the embodiment according to FIG. 1.
  • the longitudinal slots (8, 9) are shown as being open at the bottom. It is also possible to provide the slots (8, 9 or 10) laterally.
