Definitions
- the invention relates to a tapping channel for a metallurgical furnace, in particular for an electric reduction furnace, comprising at least one tapping stone and a cooling device in the region of the tapping channel.
- a tapping channel is known in which the cylindrical tapping channel is made by a made of copper, provided with cooling channels, jacket tube.
- This jacket tube is inserted into a bore in the side wall of the furnace with a filling material for positioning such that the end wall of the jacket tube is flush with the inner wall of the furnace.
- the tap holes can be offered in conventional design. For use under higher loads, water - cooled elements are available for metal, CU - stone and slag tapping.
- tapping channels the tapping channels are cooled directly, wherein the cooling medium, preferably water, is guided in the tapping channels into the interior of the oven and forwarded to the area of the Ofenausmautation.
- the cooling medium preferably water
- the invention has for its object to improve the known tapping channels, in particular their stability and durability, and to avoid the above-mentioned disadvantages. With an improved design of the tapping channel also the necessary maintenance is to be simplified and the safety can be improved.
- the cooling device is designed as a sleeve enclosing the tapping stones in the region of the furnace wall.
- tapping channel result from the relevant subclaims.
- the decisive advantage of the tapping channel according to the invention is that the tapping stones are not surrounded by the sleeve over the entire length.
- the tapping stone facing the interior of the oven (in the case of multipart design) or tapping stone section (with one - part tapping stone) is not surrounded by the sleeve.
- This tapping stone is flush with the lining of the furnace.
- the cooling medium is passed only from the outside in or on the sleeve made of copper.
- the tapping channel is cooled indirectly, due to the high thermal conductivity of the copper sleeve. No cooling medium is conducted into the interior of the oven, since the cooling channels in the sleeve are located only outside the furnace shell.
- the natural leaching by hot slag / metal, etc. are minimized and the tapping channel is retained in the preconfigured form.
- the position / position of the tap hole is defined.
- the lining around the tap hole remains intact.
- the used / worn tapping stones can be easily removed.
- the cooling device according to the invention enables easy / easy installation of the new tapping stones, whereby inexpensive standard stone formats can be used.
- Fig. 1 in a sectional side view of a tapping channel in a known
- FIG. 2 is a sectional plan view of the tapping channel of Figure 1, Fig. 3 in a sectional side view of a tapping channel according to the invention and
- FIG. 4 is a sectional plan view of the tapping channel of FIG. 3rd
- a tapping channel 1 is shown in a known embodiment, which is arranged in a taphole 2 of a furnace consisting of furnace wall 3 and lining 4.
- FIG. 2 shows the tapping channel 1 from FIG. 1 in a sectional top view.
- the tapping channel 1 consists of several tapping stones 5, 6, 7, 8.
- the tapping stone 1 points towards the interior of the furnace and the tapping stones 7, 8 are located outside the furnace wall 3 and are of a sheet metal construction 9 Surrounded by stabilization.
- FIG. 3 shows the tapping channel 1 according to the invention in a sectional side view.
- Three tapping stones 10, 11, 12 are arranged in a tapping hole 2, wherein the tapping stone 10 pointing into the interior of the furnace terminates flush with the lining 4 of the furnace.
- the outer tapping stone 12 facing away from the furnace projects beyond the furnace wall 3 of the furnace.
- a projection 13 is attached to the furnace wall to support the tapping stone 12.
- the tapping stones 11, 12 are surrounded by a cooling device in the form of a sleeve 14.
- the sleeve 14 is flush with the end face of the tapping stone 12 on the outside of the furnace.
- the sleeve 14 protrudes partially into the lining 4 of the furnace.
- the direct area on the furnace inner wall is not included by the sleeve 14.
- the last tapping stone 10 pointing into the interior of the oven is not enclosed by the sleeve.
- the tapping channel 1 is shown in a sectional plan view.
- the sleeve 14, which consists for example of solid copper, is in their from the Furnace wall 3 outwardly projecting region with a cooling channel 15 which is annular in the embodiment shown.
- ports 16, 17 are provided for the cooling water supply and the cooling water discharge.
