Definitions
- the invention relates to a pouring device for metallurgical vessels, in particular for steel melts, with slide plates which can be placed in series one behind the other and pushed out again, into which filters can be inserted, and a dip tube protruding into a mold, and a method for controlling the flow rate of a melt.
- a ceramic filter for cleaning metallurgical melts, in particular steel melts, which can be installed in refractory wear parts through which melt flows.
- several slide plates performing different functions are designed as slide-through closures, individual plates being arranged on rails one behind the other under a vessel opening and being pushed out again.
- the spout closure known from this document is intended to enable a fast, reliable replacement of clogged filters during the casting operation.
- Replacing a filter is only intended as a complete component. Replacing the filter element is associated with an interruption in the melt supply into the mold. Depending on the duration of this fault, the casting speed must be reduced significantly in order to be able to continue the casting process Chill mold, which leads to a significant loss in quality of the strand concerned
- the invention has set itself the goal of creating a pouring device for metallurgical vessels, in which the outflowing liquid metal is constantly filtered with uniform flow conditions in the dip tube
- the immersion pouring tube is closed by a slide plate which has a filter part which can be displaced transversely to the pouring direction and which keeps the free passage cross section constant in the immersion pouring tube.
- the flow rate of the melt flowing through the immersion pouring tube is recorded, which at the same time is a measure of the clogging of the filter openings represents, and the slide plates are moved in a suitable manner
- slide plates are used, which have a filter part that has openings arranged in the casting direction and have at least one full-walled plate part.
- actuators are provided with which the slide plates in the direction of travel (x direction), and additionally in the same plane, but perpendicular to this These actuators can be moved (ie in the y direction) are connected via control devices with measuring elements with which the flow through the immersion pouring tube can be detected.
- the free cross-section can be enlarged or reduced during the casting operation.
- the device according to the invention enables a constant operating sequence over any length of time, since the filter segments can be exchanged without influencing the operating sequence.
- FIG. 1 An example of the invention is shown in FIG. 1.
- FIG. 1 shows a distributor 11, not shown in detail, which has a distributor pouring stone 12 with a pouring channel 13.
- the distributor pouring stone 11 is with an upper guide plate 21 and one in the
- Slide plates 23 can be pushed between the upper guide plate 21 and the lower guide plate 22.
- the individual slide plates have two full-walled plate parts 24, which are arranged on both sides of a filter part 25. Openings 27 are provided in the filter part 25, which are still completely open in the left part of the figure and are at least partially added as a filter part 26 in the right part of the figure.
- the slide plate 23 are connected to actuators 31 acting in the conveying direction (x direction) and actuators 32 acting transversely to the conveying direction (i.e. in the y direction).
- the actuators 31 and 32 are connected to a control device 33, which with measuring elements 34 for flow rate detection and with measuring elements 35 for
- the distributor pouring stone 12 has a pouring channel 13 which continues below the slide plates as an immersion pouring tube 28, which projects into a mold 41 (not shown).
- the slide plate 23 can be moved, as indicated.
- a partial area of the filter part 26 and a partial area of the full-walled plate part 24 can be located under the pouring tube.
- Actuator acting in the conveying direction (x-direction) 32 Actuator acting perpendicular to the conveying direction (i.e. in the y-direction)
