Definitions

  • the invention relates to a device for guiding a metallurgical melt, in particular a molten steel, with one adjoining a metallurgical vessel Drain tube.
  • the invention has for its object a change in the inflow of Molten metal from a metallurgical vessel into a downstream vessel below to enable favorable flow conditions.
  • the object is achieved in that in the bottom of the vessel an outlet nozzle is arranged with a spherical surface formed at the lower end is that protrudes sealingly into the entrance of the pouring pipe, which is articulated on the bottom of the vessel is stored.
  • This allows the flow of the molten metal in one subsequent vessel can be influenced, so that on the one hand unfavorable flow conditions be avoided and secondly horizontal mixing is achieved.
  • the direction can be changed by moving the pouring spout the movement impulse of the melt flowing into the lower vessel to be changed. Due to additional constructive measures, too a horizontal displacement of the pouring pipe must be taken into account. Associated with it is an improvement in the degree of purity and the surface quality of the Continuous casting product. In addition, an alignment error when mounting Spout pipes are corrected.
  • the movability of the pouring pipe becomes such achieved that the pouring spout is gimbal-mounted on the bottom of the vessel.
  • the motion drive is achieved according to other features in that a bearing shaft for a first outer gimbal connected to a rotary actuator is.
  • the movement of the pouring pipe results from that in the first, outer gimbal a second, inner gimbal by means of a shaft running parallel or perpendicular to the bearing shaft is stored.
  • the bearings for the pivotable bearing shaft of the first, outer gimbal arranged on the bottom of the vessel.
  • the sealing effect when the spherical shape rolls off is achieved by that the entrance of the pouring pipe in its cross-sectional shape with a straight Section begins by way of an arc section in the cylindrical flow channel merges, the spherical surface of the spout partly on the straight section partly lies tightly against the arch section.
  • the application of the invention is advantageously such that the metallurgical Vessel consists of a distributor vessel for a continuous caster. Thereby can the flow into the deeper arranged vessel with the mentioned horizontal Mixing can be introduced.
  • pouring tube is made of there is a dip tube for a continuous casting mold.
  • the only figure represents an axial cross section through a vessel bottom metallurgical vessel with discharge nozzle and pouring pipe.
  • a metallurgical vessel 1 with a vessel bottom 1a has a device for Guiding the flow of a metallurgical melt, e.g. a steel melt, and a pouring pipe 2 adjoining the metallurgical vessel 1.
  • a metallurgical melt e.g. a steel melt
  • a pouring pipe 2 adjoining the metallurgical vessel 1.
  • the articulated movement of the pouring spout 2 is e.g. through a gimbal Suspension on the bottom of the vessel 1a allows.
  • the movement is via a bearing shaft 4 generated for a first, outer gimbal 5, the bearing shaft 4th is connected to a (only indicated) rotary actuator 6.
  • outer gimbal 5 is a second, inner gimbal 7 by means of a parallel or perpendicular to the bearing shaft 4 shaft 7a pivotally mounted.
  • the pivot bearing 13 for the pivotable bearing shaft 4 of the first outer gimbal 5 are arranged on the vessel bottom 1a.
  • Carbon fiber seal 2e inserted to seal against negative pressure.
  • the outlet nozzle 3 can also cut an annular groove 8 that cuts the flow channel 2d to supply inert gas, which also counteracts the outside air.
  • the entrance 2c of the pouring tube 2 begins symmetrically in its cross-sectional shape 9 each with a straight section 10, which has a curved section 11 in passes over the cylindrical flow channel 2d, the spherical surface 3b of the outlet nozzle 3 partly on the straight section 10 partly on the curved section 11 fits tightly even during an angular movement.
  • the metallurgical vessel 1 consists of one Distributor 12 for a continuous caster. It is also assumed that the pouring tube 2 consists of an immersion tube 2a for a continuous casting mold, with its mouth 2b immersed below the melt level.
  • the dip tube 2a can be moved such that the direction of the movement pulse of the in the continuous casting mold flowing melt, which the flow field in the Continuous casting mold is significantly influenced, changed. With a horizontal one Shifting arrangement can be due to a combination of both movement paths the position and orientation of the pipe piece immersed in the melt are independent from each other.
  • the flow in the continuous casting mold through a Measurement of a physical quantity assessed and in the form of a descriptive Key figure can be fed to a control unit.
  • a measuring system e.g. on Speed measuring system for continuous casting molds or in a simple case can also use only several sensors to record the surface profile in the Continuous casting molds are used.
