Definitions
- the invention relates to a method for closing a vessel located in the bottom of a vessel filled with metallic melt, in particular for steel
- closure devices are used with which it is possible to retain a remainder of the molten metal and the slag in the vessel Metal or slag is exposed
- DE 34 37 810 discloses a closure device for a tap opening in the bottom of a metallurgical vessel, in which a shut-off device is provided outside the vessel, in particular a metallic heating furnace, in which a lower shut-off device can be moved from the outside against the tap opening in the interior of the vessel a tube is arranged which can be lowered from a release position into the blocking position and the mouth of which lies against the edge of the tap opening. In the lowered blocking position, ⁇ eselfbare full material is brought through the tube into the tap opening
- the invention has set itself the goal of providing a method and a corresponding device for the repeatable closing of a tap opening of a metallurgical vessel with which, with a high overall service life, a secure shut-off even without the tilting of the swamp which is necessary for a bottom-up procedure
- the invention achieves this goal by the characterizing features of method claim 1 and device claim 6
- a compressible material is provided on the forehead of the closing element, which is pressed together in the region of the tap hole when it contacts the bottom of the vessel
- the sealing material is protected against influences from the melt and from the molten metal.
- this compressible material used for sealing purposes from a refractory material and in the inner region facing away from the mouth, one provided on the forehead of the closing device Insert groove The remaining inner area of the groove is left free and serves as a chamber for a gas which is held in this chamber to protect the sealing material as it passes through the melt
- This gas can originate from a solid or liquid medium which is brought onto the compressible material and gasified under the action of heat.
- it can be added as a gas or a gas is used which during the residence time of the compressible material in the molten bath, experience has shown that it takes less than 30 seconds to expand when heated and to displace the melt during expansion, the total volume of which is sufficient to maintain this process all the time.
- the entire process of closing takes place in such a way that the tubular closing element is guided through the slag and liquid melt in the upright furnace until it touches the inner wall of the vessel bottom and seals it tightly to prevent the melt from flowing out.
- the tap hole is still open, so that the melt or slag in the interior of the tubular element and in the tap hole leaves the furnace vessel.
- the shut-off device, a slide or a flap, which is arranged outside the vessel is closed.
- a tool can be guided through the tubular closing element with which the tap opening can be treated, for example by cutting off bears or the like.
- a device for example a goalie machine, can be brought through the tubular closing element into the tap hole, with which the refractory material is repaired. If the tap opening is considered to be usable, a nebulizable material is introduced into the tap opening in a known manner. This serves to protect the shut-off device and to facilitate pouring after the shut-off has been opened
- the head of the closing element is used as
- This interchangeable part is replaced if necessary after one or more closing operations and is fitted with a new sealing lip, i.e. a groove and the compressible refractory material.
- This interchangeable part can have a wall thickness that is significantly greater than that of the remaining tubular closing element.
- the walls of the groove have the task of protecting the sealing material as it passes through the melt. If the sealing material, such as a mat or a molded part made of fibers, the bottom of the has reached the metallurgical vessel, the material of the walls of the groove should not interfere with the compression of the sealing material.
- a metallic material that is designed as a compensator can be used as a material.
- a metallic material can be used that after passing through the melt, that is to say approximately 15 up to 30 seconds, at least softens, melts or chars
- Cardboard can be used, which has a sufficient service life and which chars on contact with the melt
- the bottom ie the forehead of the interchangeable part, has a conical surface that tapers towards the center axis.
- a corresponding shape of the bottom of the groove can be used, with the result that the thickness of the sealing compound that is later compressed the refractory fibers, is kept almost constant in this way, a particularly high level of tightness is reliably achieved
- Figure 1 shows a section through the furnace barrel with a straight base of the
- Closure element Figure 2 A section with an adapted base area of the closure element
- FIG. 3 A sketch of an interchangeable part
- FIG. 1 shows a section through part of a metallurgical vessel 10 with the metallic vessel jacket 11 and the refractory vessel lining 12.
- a tap opening 14 is provided in the vessel bottom 13, the mouth 16 of which is closed by a shut-off device 20, here by a flap 21
- the tap opening 14 has a refractory lining 17 which may have a conical bevel in the area of the inlet 15
- a tubular closing element 31 is guided, on the end face 32 of which a groove 33 is provided.
- a groove 33 is provided in the groove interior 34 there is compressible material F introduced
- an interchangeable part 37 is provided which can be attached to the main body 39 via a releasable connection 36
- a bore is provided in the left part of the closing element 31, through which a gas G can be conveyed into the groove region 34 of the groove 33
- Inner diameter d f of the closing element 31 is equal to or larger than the diameter D of the tap opening 14
- FIG. 2 shows a metallurgical vessel 10 filled with metallic melt M, on which slag S floats, which is covered by a lid 19 through which the main body 39 of the closing element 31 can be guided.
- the closing element 31 is held by a support arm 42 which can be moved vertically by a displacement drive 41. Furthermore, the closing element 31 can be rotated about its main axis I by a rotary drive 43
- a filler 45 is applied to the main body 39 of the closing element 31 to facilitate the supply of material capable of being fed into the tap opening 14. Furthermore, there is a supply 44 for repair compounds, for example the gate paste compound T.
- the head 37 of the closing element 31 is designed as an interchangeable part.
- the base 35 is chamfered, the walls 36 being guided axially parallel to the main axis I.
- the base surface 35 is the current state of the entrance 15 of the Refractory lining 17 of the tap opening 14 is also reproduced.
- the walls 26 are axially parallel to the
- the mouth 16 of the tap opening 14 can be closed by a shut-off device 20, here by a slide 22
- the inside diameter d of the closing element 31 is smaller than the inside diameter D of the tap opening 14
- FIG. 3 shows a part of the closing element 31, namely the main body 39 and the interchangeable part 37 fastened via a detachable connection 38.
- the groove 33 has a base surface 35 arranged at right angles to the main axis I and has walls 36, which is designed as a compensator in the left-hand side and, for example, is made of cardboard in the right-hand side.
- Compressible material F is provided in the inner region 34 of the groove 33.
- a space is left up to the mouth of the walls 36, in which gas can accumulate a liquid or solid medium H accumulates after the transition to the gas phase due to the action of heat
- the base surface 35 of the groove 33 having the walls 36 is arranged obliquely.
- the compressible material F is introduced in the form of a molded part in front of this inclined base surface 35.
- the groove 33 is guided through a through the main body 39 and the interchangeable part 37 Bore a gas G can be supplied
