Description
Technical field
Tapping hole is the utility model is related to, especially a kind of elliptical aperture thickeies formula tapping hole.
Background technology
Converter and electric furnace need to pour out molten steel using tapping hole when toppling over molten steel, are circular hole in existing tapping hole,
Liquid steel temperature is high, after long-time service, tapping hole can be produced and washed away and corrosion function, the region for passing through tapping hole lower part molten steel
Tolerance reduces, and causes tapping hole to scrap, it is necessary to the tapping hole more renewed could be produced normally, improves the production of enterprise
Cost, it is time-consuming and laborious to remove and install process, reduces production efficiency, adds the labor intensity of worker, therefore, how can extend
The service life of tapping hole, reduces the production cost of enterprise, improves production efficiency, and it is difficult to become insoluble technology for a long time
Topic.
In view of the foregoing, now develop a kind of elliptical aperture and thicken formula tapping hole.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of elliptical aperture thickeies formula tapping
Mouthful, the circular hole in existing tapping hole is changed to elliptical aperture, centre bore is deviated to non-by steel face direction；Tapping hole end face uses inclined-plane
Design；By the improvement of above-mentioned three aspects, the eddy current effect of steel stream is effectively reduced, increases body thickness of the tapping hole by steel face,
Significantly improve the tapping hole service life.
The utility model to achieve these goals, adopts the following technical scheme that：A kind of elliptical aperture thickeies formula tapping hole, is
By：Main pipeline, elliptical aperture, inclined-plane are formed；Elliptical aperture is set in cylinder main pipeline, and the long diameter and main pipeline of elliptical aperture erect
It is located to diameter in same vertical lines, the horizontal direction diameter of the short diameter parallel and main pipeline of elliptical aperture, the center of circle of elliptical aperture
Spacing between the center of circle of main pipeline is a, and a is the 8~15% of main pipe diameter, below elliptical aperture under minimum point and main pipeline
The spacing of square minimum point is more than the spacing of peak and peak above main pipeline above elliptical aperture, and main pipeline front end surface is set
For inclined-plane, the angle on the inclined-plane and vertical plane is 15~20 °, below main pipeline where minimum point in vertical lines and main pipeline
Horizontal direction spacing between vertical lines where square peak is c, c 100-150mm.
The spacing of minimum point and minimum point below main pipeline is more than peak and master above elliptical aperture below the elliptical aperture
More than twice of the spacing of peak above pipeline.
The beneficial effects of the utility model are：Circular hole in existing tapping hole is changed to elliptical aperture, center by the utility model
Kong Xiangfei is deviated by steel face direction；Tapping hole end face uses inclined design；By the improvement of above-mentioned three aspects, steel stream is effectively reduced
Eddy current effect, increase tapping hole by the body thickness in steel face, significantly improve the tapping hole service life.Simple in structure, production cost is low
Honest and clean, using effect is notable, and this product has had been obtained for industry experts favorable comment consistent with users' since coming into operation,
This product wide market, is adapted to popularity application.
Brief description of the drawings

In Fig. 1,2：Main pipeline 1, elliptical aperture 2, inclined-plane 3.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Elliptical aperture 2 is set in cylinder main pipeline 1, and the long diameter of elliptical aperture 2 is with the vertical diameter of main pipeline 1 positioned at same
In vertical lines, the short diameter parallel of elliptical aperture 2 and the horizontal direction diameter of main pipeline 1, the center of circle and the main pipeline 1 of elliptical aperture 2
Spacing between the center of circle is a, and a is the 8~15% of 1 diameter of main pipeline, and 2 lower section minimum point of elliptical aperture and the lower section of main pipeline 1 are minimum
The spacing of point is more than the spacing of 2 top peak of elliptical aperture and 1 top peak of main pipeline, and 1 front end surface of main pipeline is arranged to
Inclined-plane 3, the angle on the inclined-plane 3 and vertical plane is 15~20 °, vertical lines and main pipeline 1 where 1 lower section minimum point of main pipeline
Horizontal direction spacing between vertical lines where the peak of top is c, c 100-150mm.
The spacing of the 2 lower section minimum point of elliptical aperture and 1 lower section minimum point of main pipeline be more than 2 top peak of elliptical aperture with
More than twice of the spacing of 1 top peak of main pipeline.
