Definitions
- Shaped component made of refractory material
- the invention relates to a shaped component made of refractory material having the features in the preamble of claim 1 protection.
- the area of the stitch hole channel of a melting furnace, in particular a shaft furnace such as e.g. a cupola, is subject to heavy wear. Therefore, the taphole channel must be rebuilt from time to time. For this purpose, the melting furnace has to be shut down and cleared so that the area surrounding the taphole channel can be re-lined not only from the outside, but also from the inside. The newly introduced refractory material must then dry before operation can continue. Since operation of the shaft furnace is not possible in the dry season, considerable malfunctions occur.
- the taphole channel is located within a larger tap hole of the shaft furnace.
- the tapping opening is also referred to in the jargon as a chapel.
- an arrangement for lining a chapel of a blast furnace is known, wherein molded components made of refractory material are used. It is a first prefabricated mold component and least another prefabricated mold component provided. The mold components engage each other in a form-fitting manner and are configured in such a way that the lining of the chapel can be made simple and time-saving.
- the taphole channel is located in the middle region of a larger of the mold components.
- the invention is based on the object to show a molded component of refractory material to lining a tap hole of a shaft furnace, the service life of the tap hole and thus the entire lining of the tap hole is increased.
- the innovation consists in that the tap hole channel is arranged on the underside of the molding component, wherein the width of the prefabricated tap hole channel increases from the furnace interior to the outside of the furnace.
- the furnace-outer side has a central portion and recessed relative to the central portion side portions.
- flank portions are arranged, which include an angle in the range of 20 ° to 70 °, in particular in a range of 30 ° to 60 ° with the central longitudinal axis of the needle hole channel ,
- the taphole channel itself is preferably not wider at its outer opening than the central portion and preferably as wide as the central portion. Due to the coordinated width of the turbulent flow areas of the side of the central portion or side of the taphole channel is minimized as far as possible, the flank sections also prevent premature leaching in the area of the broad sides of the needle hole channel.
- the tap hole channel has a rectangular cross-section, wherein its width in each cross-sectional plane is at least twice as large as its height.
- Figures 1 and 2 show in plan view and in a perspective view of a molded component 1 made of refractory material for lining a non-illustrated tapping opening of a shaft furnace.
- the molded component is formed in its geometry substantially parallelepiped with a length L of 1,400 mm, a width B of 700 mm and a height H of also 700 mm.
- Essential is the configuration of the tap hole 2, which is shown in Figures 1 and 2 with a broken line.
- the tap hole channel 2 has on its side facing the furnace interior side 3 a width B1 of 150 mm, which increases in the direction of the oven-side 4 to 400 mm.
- the middle side 5 and the side sections 6 extend parallel to one another in their orientation, the middle section 5 protruding from the side section 6 in this exemplary embodiment by approximately 200 mm or, as the case may be, in FIG .,
- the side portions 6 are set back relative to the central portion 5 by 200 mm.
- flank sections 7 which with the central longitudinal axis of the needle hole channel 2 an angle in a range of 20 ° to 70 °, preferably in a range of 30 ° to 60 °.
- the taphole channel 2 at its outer opening 8 is not wider than the middle section 5, but is virtually as wide as the central section 5. In this embodiment, that would be 400 mm, with the side sections 6 and the flank sections 7 total 300 mm omitted.
- the flank sections 7 are approximately as wide as the side sections 6.
- the tap hole channel 2 has a rectangular cross section, as can be seen in Figure 2.
- the width B1 of the taphole channel is at least twice as large as its height H1 in each cross-sectional plane.
- FIGS. 1 and 2 also show a groove which, with the exception of the underside of the molded component 1 receiving the taphole channel 2, extends over all three sides of the molded component in the region of the outer circumference.
- the groove serves to introduce refractory material in order to cast the molded component 1 within the chapel or the tapping opening of the shaft furnace and thus to anchor the molded component.
- the remaining between the mold part 1 and the wall of the tap not shown free spaces are poured with refractory material. This applies both to the area of the groove 9 and to the other long sides.
- the free spaces to be poured out can be relatively narrow.
- the molded component 1 according to the invention is also distinguished by the fact that it has a significantly greater length in relation to the height and width, which contributes significantly to the improvement in service life. While conventional molded components have a length of, for example, 500 mm, the length L of the molded component is at least twice as large, ie it is at least 1,000 mm. With regard to the height and width of the molded component 1, it can be said that the length L is at least twice as large as the height H or width B of the molded component 1.
