Definitions
- the invention relates to a sealing plug for a metallurgical melting vessel.
- Such plugs serve to regulate the outflow quantity of a molten metal in the region of an outlet opening of an associated melting vessel, for example a tundish.
- Such a sealing plug is usually constructed as follows: It has a rod-shaped body of at least one refractory ceramic material, which has a first upper end and a second lower end respectively. From the first end, a bag-like opening extends in the axial direction of the rod-shaped body towards the second end, this opening terminating at a bottom spaced from the second end of the body. A gas outlet channel having a smaller cross-sectional area than the opening connects the bottom of the opening to a surface portion in the region of the second end of the body. Adjacent to the first end, the opening has peripherally fixing means which for fixing a corresponding holding device, usually a support rod serve, via which the closure plug is attached to a manipulator. With the help of the manipulator, the plug is moved up and down to either seal the outlet opening of the melting vessel or release to an adjustable opening width.
- a known plug of the generic type is known from EP 0 358 535 B2 known. The disclosure is referred to.
- the opening and the subsequent gas outlet channel serve (also) to guide a gas through the closure plug into the molten metal.
- the gas serves for the secondary metallurgical treatment of the melt. For example, it is intended to remove metallic inclusions in the melt by flotation. Important in this context is a constant flow of the treatment gas.
- sealing plug If the sealing plug is in a position away from the outflow opening of the melting vessel, molten metal flows out. In this case, by the flow of the molten metal, a negative pressure below the lower end of the sealing plug arise. This negative pressure can become so great that the gas flow breaks off. At the same time, air can be sucked in. Both are undesirable.
- the EP 1 401 600 B1 describes a generic plug (there called monoblock plug), in which a calibration device is installed in the gas outlet. This consists of a rod which has one or more axial gas channels. In this way, a certain flow resistance should be set.
- the known device is complicated to manufacture. In addition, it is difficult to set a certain flow resistance.
- the post-published WO 2005/059185 describes a plug with an insert in the plug opening through which a tube is passed. From the FR 2787045 a stopper is known in the sack-shaped opening a Venturi nozzle is designed for a gas passage.
- the invention has for its object to offer a sealing plug, which is easy to manufacture and with the transport and the supply of gas, in particular inert gas, can be done effectively and safely in a molten metal.
- the aforementioned bag-like opening in the plug body usually has a circular cross-sectional area with a diameter of several centimeters.
- the gas outlet channel adjoining the opening has a much smaller cross-sectional area, usually with a diameter of only a few millimeters.
- the large opening usually extends over much more than half the total length of the plug body, while the gas outlet channel extends only in the second lower end portion and is correspondingly short.
- the invention is based on the idea to move the means for adjusting the gas flow resistance from the region of the gas outlet channel at the lower, second end of the sealing plug in the overlying opening.
- the opposite the gas outlet very much larger opening must be at least partially filled with a corresponding filler.
- This filler body can extend over a corresponding partial length of the opening (viewed in the axial direction of the plug body) and thereby fills the entire cross-sectional area of the opening.
- the displacement of the means for adjusting the gas flow resistance in the opening provides numerous opportunities to adjust the flow resistance individually, depending on where the opening over which Length of the filling body is formed and how many channels are arranged in which form within the filling body.
- the invention in its most general embodiment relates to a sealing plug for a metallurgical melting vessel having the features of claim 1.
- the said bottom of the opening can be designed arbitrarily. It can be more or less perpendicular to the axial direction of the body. It can also be curved, for example concave or convex. It is also possible, funnel-shaped view of the bottom portion - viewed in the axial direction of the sealing plug, with direct connection to the following gas outlet.
- the filler (with the gas channels running therein) can - as stated - have almost any length. Its length will depend on, among other things, how large the flow resistance is, which is desired for the gas flow in the particular application. Normally, the filler - viewed in the axial direction of the body - have a length which is at least 5% of the length of the opening. This value can be increased according to various embodiments also> 10%,> 15%, to values> 25%.
- the arrangement of the filling body within the opening is almost arbitrary.
- the packing may be tight except for the gas passage area.
- An arrangement of the filling body immediately adjacent to the bottom of the opening has fluidic advantages. For this purpose, it is to be ensured that the bottom-side opening of the gas channel, which runs in the filler body or in the contact region between filler body and body of the sealing plug, is in fluid communication with the gas inlet-side opening of the gas outlet channel at the bottom end of the plug body (at the so-called plug head).
- closure plugs of the type mentioned are produced by isostatic pressing.
- the opening and the gas outlet channel is formed in situ.
- the filler can be subsequently poured. A possible manufacturing method for this is shown in the context of the subsequent description of the figures.
- the filler may also be a pressed part, which is used during manufacture or subsequently in the opening of the pre-pressed stopper body.
- the gas channel can run through the filler. It can also be formed on the outer wall of the filler in the form of a groove.
- the wall of the opening delimits the gas channel on the outside.
- the wall of the opening may have a groove and the filler (its peripheral surface) then bounds the groove on the inside, so that a gas channel is formed.
- the gas channel may be arranged spirally around the central longitudinal axis.
- the length of the filling body can be increased.
- a particular advantage of the design according to the invention is that the filler is disposed within the large opening and thus has a considerable cross-sectional area, which makes it possible to guide the gas channel, for example, meandering or helical through the filler or between filler and body. Thus, its length is sometimes much greater than the shortest distance between its end (bottom and top) outlet openings.
- a porous filter such as a porous, temperature-resistant filter paper or with a porous plug.
- a porous, sponge-like element can also be provided as part of the filling body.
- FIG. 1 is to recognize a lower portion 10 of a rod-shaped body of a sealing plug.
- the rod-shaped body consists of a refractory material of conventional type.
- an opening 12 extends in the body 10 and extends from an upper end (not shown) of the body 10 towards a second lower end 14 and at a distance to this end in the area of a floor 16 ends.
- a gas outlet channel 20 extends coaxially to the central longitudinal axis M - M as far as the lowermost section of the second end 14.
- FIG. 1 shows a step of producing the closure body, wherein the body 10 was first prepared in a conventional manner by isostatic pressing.
- a wire 22 is drawn in via the gas outlet channel 20, wherein the wire 22 at its free lower end has a thickening 22 d, while the portion in the gas outlet channel 20 rests, has a larger diameter (the gas outlet channel 20 largely fills) than the overlying portion 22a, which extends through the opening 12 to the first upper end of the closure body and is temporarily fixed there in a manner not shown.
- a refractory concrete is poured into the opening 12 and advanced by means of a plunger until about the hatched area above the gas outlet channel 20 is filled with the still viscous concrete, which encloses the wire 22 in the section 22a.
- the wire 22 is again removed against its feed direction. For this purpose, the wire 22 can be gripped on the thickening 22d and pulled down.
- a corresponding gas channel 26 is formed which continues into the gas outlet channel 20.
- burnable bodies can also be used. During the subsequent firing of the sealing plug, burning out of these inserts results in the formation of the desired gas channels in the desired arrangement and geometry.
- the pressed filler insert 24 has a spiral-shaped gas channel 26, whose lower outlet-side end extends coaxially to the central longitudinal axis M-M of the body 10.
- the gas channel 26 is formed in the transition region of packing 24 and body 10.
- the filling body 24 has a helical groove 26n on its circumferential surface 24u, which is bounded on the outside by the boundary wall 12i of the opening 12. Together of filler 24 and body 10 while the gas channel 26 is formed, which creates a fluidic connection from the opening 12 to the gas outlet 20.
