Definitions
- the invention relates to a method for closing a in the bottom of a metallic melt filled vessel, especially for steel Tap opening, with a tubular closing element arranged in the furnace vessel, which is vertically movable to and from the entrance of the tap hole, and one shut-off device and a device arranged below the bottom of the vessel to carry out the procedure.
- a closure device for a tap hole in Bottom of a metallurgical vessel known in which outside the vessel, in particular a metallic heating furnace, a shut-off device is provided in which a lower shut-off device can be moved from the outside against the tap opening.
- a tube is arranged inside the vessel, which extends from a release position into the Locking position can be lowered and its mouth is against the edge of the Tap hole. In the lowered locking position, pourable filling material becomes brought through the tube into the tap hole.
- the invention has set itself the goal of a method and a corresponding Device for the repeatable closing of a tap opening of a to create a metallurgical vessel with a long overall life safe shut-off even without tipping the Vessel is possible.
- the invention achieves this goal by the characterizing features of Process claim 1 and device claim 6.
- a compressible material is on the forehead of the closing element provided for closure when it comes into contact with the bottom of the vessel is compressed in the area of the tap hole.
- This gas can come from a solid or liquid medium that is on the compressible material is brought and gasified under the influence of heat. It can be continuously supplied as a gas in a further advantageous embodiment or a gas is used, which during the residence time of the compressible material in the melt pool, experience has shown that it takes less than 30 seconds, expands when heated and displaces the melt as it expands, its total volume being sufficient for this process all the time maintain.
- the overall process of closing is such that the im Upright furnace through the slag and liquid melt the tubular Closing element is guided until it touches the inner wall of the vessel bottom and seals them tightly to prevent the melt from flowing out. At that time it is Tap hole still open, so that the inside of the tubular element and melt or slag in the tap hole leaves the furnace vessel. Then the shut-off device arranged outside the vessel is turned on Slider or a flap, closed. There is now the possibility that Inspect tap hole. This can be done by direct inspection, however done by a camera or an endoscope. Furthermore, by the tubular closing element a tool with which the tap hole can be treated, for example by hitting bears or the like.
- a device for example a goalie machine, through the tubular Closing element are brought into the tap hole, with which a repair of the Refractory material is carried out.
- a free-flowing material is known in the tap hole brought. This serves to protect the shut-off device and to facilitate Pour on after opening the barrier.
- the head of the closing element is used as Exchange part trained.
- This exchange part is, if necessary, for one or exchanged several closing processes and with a new sealing lip, i.e. one Groove and the compressible refractory material.
- This interchangeable part can have a wall thickness that is significantly larger than that of the remaining tubular closing element.
- the walls of the groove have the task of the sealing material during the Protect driving through the melt. If the sealing material, for example, 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 is said Do not interfere with the compression of the sealing material.
- a material is an option metallic material, which is designed as a compensator. Furthermore, a metallic material are used, which after passing through the melt, ie in about 15 to 30 seconds, at least softens, melts or chars. For example, one Cardboard are used, which has a sufficient service life and which Charred contact with the melt.
- the Reason i.e. the forehead of the interchangeable part, have a conical surface leading to Center axis tapers to a point.
- a corresponding shape of the bottom of the groove can be used with the result that the thickness of the later compressed sealing compound, ie the refractory fibers, is kept almost constant. In this way, one particularly high tightness safely achieved.
- FIG. 1 shows a section through part of a metallurgical vessel 10 the metallic vessel jacket 11 and the refractory vessel lining 12.
- Im Vessel bottom 13 is a tap opening 14 is provided, the mouth 16 through a Shut-off device 20 is closed, here by a flap 21.
- the tap opening 14 has a refractory lining 17, which in the region of the Entrance 15 may have a conical bevel.
- a tubular closing element 31 guided, on the end face 32 a groove 33 is provided.
- Compressible material F is in the groove interior 34 brought in.
- a detachable Connection 36 on the main body 39 attachable interchangeable part 37 is provided.
- the inner diameter d i of the closing element 31 is equal to or larger than the diameter D i of the tap opening 14.
- FIG. 2 shows a metal melt M on which slag S floats, filled metallurgical vessel 10, which is covered by a lid 19 by 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 is moved by a displacement drive 41 is vertically movable. Furthermore, the closing element 31 is by a rotary drive 43 rotatable about its main axis l.
- a filling funnel 45 is located on the main body 39 of the closing element 31 applied to facilitate the flow of pourable material into the Tap opening 14. There is also a feed 44 for repair compounds, for example the Torkret Masse T.
- the head 37 of the closing element 31 is designed as an interchangeable part.
- the base 35 is chamfered, the walls 36 are guided axially parallel to the main axis l.
- the Base area 35 On the left side of the picture is the Base area 35 the current state of the entry 15 of the refractory lining 17 reproduced the tap opening 14.
- the walls 26 are also axially parallel to Main axis l guided.
- the compressible material F is shown how it is deformed and one tight seal between the molten metal M and the tap opening 14 forms.
- the mouth 16 of the tap opening 14 is through a Shut-off device 20, here can be closed by a slide 22.
- the inside diameter d i of the closing element 31 is smaller than the inside diameter D i of the tap opening 14.
- Figure 3 shows 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 one arranged at a right angle to the main axis 1
- Base 35 on and has walls 36 which in the left side as Compensator is formed and in the right side made of cardboard, for example is constructed.
- In the inner region 34 of the groove 33 is compressible material F intended.
- a free space is left up to the mouth of the walls 36, in which gas that can accumulate from a liquid or solid medium H after Transition to the gas phase due to heat accumulates.
- the base 35 of the walls 36 having groove 33 arranged obliquely.
- this sloping base 35 In front of this sloping base 35 that is compressible material F introduced in the form of a molded part.
- a gas through a bore through the main body 39 and the interchangeable part 37 G feedable.
