Definitions

  • the invention relates to a refractory ceramic Gas Crowelement, that is, a gas purging device, especially for metallurgical vessels with which metal melts are treated, for example, for a ladle or a tundish.
  • a gas purging device especially for metallurgical vessels with which metal melts are treated, for example, for a ladle or a tundish.
  • These vessels / aggregates include those for non-ferrous metals such as lead.
  • a generic gas purging device as shown in the DE 197 55 199 C1 is known, has a refractory, ceramic gas purging plug and a, arranged at the bottom of the gas purging gas distribution chamber from which gas-permeable areas extend through the gas purging plug to the gas outlet end of the gas purging plug.
  • the gas purging device comprises a gas supply line, which opens into the gas distribution chamber with a gas outlet side opening.
  • a treatment gas or a gas / solid mixture is injected into the molten metal.
  • the known gas purging device has basically proven, but requires a flexible (flexible) cover, for example, from a thin sheet. Frequent changes in gas pressure or at higher temperatures in the gas distribution chamber may limit the functionality of the cover.
  • a gas purging device in which a plate-shaped closure member is guided spring-loaded in Gaszu melt.
  • the closure member can move between corresponding stops in the gas supply pipe. In the end positions, the gas supply is interrupted.
  • the invention is based on the object to offer a refractory ceramic Gas Crowelement the generic type, which also has a high reliability even if the gas pressure fluctuates and / or the ceramic part of the Gas Kunststoffenses is partially worn.
  • the main difference to the gas flushing device according to DE 197 55 199 C1 is that in the Gasverteilhunt a plate is arranged loosely, while in the known device, a cover is fixed to the chamber.
  • the plate moves within the gas distribution chamber between a first end position (when the gas is off, for example) and a second end position (at regular gas pressure) substantially in the axial direction of the gas purging element, that is, in the main direction in which the gas is ceramic Part of the gas purging element flows through.
  • the gas may flow through the gas distribution chamber into the gas permeable portion of the refractory ceramic body even when the plate is in its (raised) second end position.
  • the plate should have in the second end position at a distance from the part of the refractory ceramic body, which is flowed through by the gas.
  • the upper part of the Gasverteilhunt (viewed in the direction of the fundamental gas flow) remains free and prevents the plate is applied directly to the bottom of the refractory ceramic body.
  • the chamber extends over at least 90% of the cross-sectional area of the body at the first end.
  • the Gasverteilhunt has a nearly identical cross-section as the adjacent refractory body, that is, both aligned in the axial direction.
  • the gas distribution chamber may be formed by a metal housing.
  • the gas supply conduit opens into a portion of the chamber opposite the refractory ceramic body. If one considers the gas purging element in a position as it is usually installed in the bottom of a metallurgical vessel, then the gas supply line in this case opens from below into the chamber. This orientation of the gas purging element also applies below, unless otherwise indicated.
  • the movable plate covers the gas supply line when the gas pressure is below a minimum value to push the plate upwards. In this lower position, the plate thus fulfills a safety function against a possible molten metal infiltration. If molten metal penetrates into the chamber, it is initially held back by the plate.
  • the plate in a porous plate, in particular an open-pored plate, the plate can even absorb molten metal. In addition, melt is prevented from flowing into the gas supply pipe 30.
  • the second end position, so the raised position of the plate can be defined by one or more attacks, training a clearance between the plate and the first (lower) end of the refractory ceramic body.
  • This at least one stop may project from the first end of the refractory ceramic body in the direction of the plate, it is also possible that the at least one stop is formed on the inside of the chamber, preferably in the vicinity of the ceramic body. It is also possible to form the stop or stops on the plate, for example by projecting nubs or webs on the side facing the ceramic body.
  • the cross-sectional area (base area) of the plate is regularly slightly smaller than the internal cross-section of the chamber in order to allow said movement of the plate in the axial direction of the gas purging device.
  • the plate is designed so that circumferentially a substantially uniform gap to the inner wall of the chamber remains.
  • the gap is dimensioned so that a good mobility of the plate results without these tilted.
  • the ceramic body may be aligned with so-called undirected porosity and / or with directed porosity.
  • Undirected porosity can be characterized by a “sponge-like structure” in which the gas is zig-zag-shaped along open pores flows through the ceramic.
  • directed porosity the gas flow is largely linear based on defined channels, slots or the like. The channels usually run in the axial direction of the purifier.
  • the plate may also be at least partially gas permeable.
  • the plate can also have a kind of sponge structure, that is a kind of "undirected porosity".
  • the plate may for example consist of a sintered metal or of a refractory ceramic part with undirected porosity.
  • an embodiment provides to cool the chamber.
  • the chamber may have a valve to which a cooling gas line is connected.
  • the chamber may have at least one wall which is part of a cooling device, for example, the bottom of the chamber may be double-walled and flowed through by a coolant.
  • the plate has at least one opening, which is penetrated by a rod which extends in the axial direction of the gas purging device, wherein the opening has a cross section which is slightly larger than the rod cross section.
  • This rod can perform several functions: First, the rod serves to guide the plate in the axial direction of the gas purging element.
  • the rod can also fulfill additional functions.
  • the rod may be a thermocouple with which the temperature in the gas purging element is measured.
  • the rod can serve as a residual strength indicator.
  • the rod may be a hollow rod whose end is closed in the ceramic body. If the hollow rod is charged with gas and the ceramic body is worn so far that the closed end of the hollow rod melts the gas escapes, the gas pressure drops accordingly and indicates the wear.
  • A-A run channels 12 through the ceramic body 10, which thus has a directed porosity.
  • a chamber 20 which extends over the entire cross-sectional area of the body 10 at the lower end 10u and is made of metal.
  • the chamber 20 has a closed bottom 20b, a circumferential wall 20w and a ceiling 20d with openings 20o in extension of the channels 12th
  • a further gas supply line 40 can be seen, which is closed to the interior of the chamber 20 out, in particular FIG. 2 shows, but also can be open.
  • a refractory ceramic plate 50 is arranged according to FIG. 1 is located on the bottom 20b of the chamber 20 and is dimensioned so that circumferentially there is a gap between the plate 50 and wall 20w.
  • the plate 50 has a so-called non-directional porosity, that is, a sponge-like internal structure, so that gas flowing in via the conduit 30 can flow through the open porosity of the plate 50.
  • the plate 50 is simultaneously raised ( FIG. 2 ) until it reaches its maximum upper position when the plate 50 abuts against the stopper 20a.
  • FIG. 2 Fig. 2 shows that there is still a distance between the top of the plate 50 and the top 20d of the chamber 20, so that the gas which has flowed through the plate 50 or between the plate 50 and the wall 20w into the space 20r, from there through the Openings 20o and the channels 12 can flow in the direction of the (not shown) molten metal.
  • the distance between the plate 50 and body 10 can be achieved by nubs extending from the bottom of the body 10 between the channels 12 and projecting downwards.
  • the axial mobility of the plate 50 is supported by a rod-shaped thermocouple 70, which by corresponding
  • Openings in the bottom 20b, in the plate 50, in the ceiling 20d extends into the ceramic body 10 and ends there at a distance from the upper end 10o of the Gas Standiatas (not shown).
  • the opening in the plate 50 is so large that the plate 50 easily moves in the axial direction A, when the gas pressure is increased or decreased.
  • FIG. 2 shows the gas purging device in the functional state, FIG. 1 the case that no gas flows; the plate 50 then fulfills a safety function by covering the gas supply line 30.
  • the closure of the gas line 40 can be dimensioned so that it melts or is destroyed when a certain temperature is exceeded in the gas distribution chamber 20, so that, for example, in the case of an unexpected increase in temperature, for example by infiltrating molten metal, a cooling gas via line 40 in the chamber can be passed to freeze the melt.
  • thermocouple 70 With the thermocouple 70, the temperature at corresponding locations in the ceramic body 10 can be measured. This also indicates indicative of a particular state of wear or molten metal infiltration
  • the embodiments of the Figures 3 . 4 differ from the embodiments according to the FIGS. 1, 2 in that adjoining the chamber 20 is an additional cooling chamber 60 which, like the chamber 20, extends over the entire cross section of the lower end 10u of the body 10, the gas conduit 40 being open at the upper end in this embodiment. This makes it possible to continuously cool the space 60 and thus also the bottom 20b of the chamber 20.
  • the cooling space 60 like the chamber 20, is formed by a metal box.
