The slag and iron discharging structure of the titanium slag electric-arc furnace comprises a pore passage main body and further comprises a slag discharging nozzle and an iron discharging nozzle which are high temperature-resistant and corrosion-resistant, wherein a slag discharging port is formed on the slag discharging nozzle; an iron discharging port is formed on the iron discharging nozzle; the slag discharging nozzle and the iron discharging nozzle are installed at two outlet ends of the pore passage main body respectively; and the slag discharging port and the iron discharging port are communicated with the pore passage main body.
Description
Technical field
The utility model relates to a kind of iron construction of slagging tap of titanium slag electric arc furnaces, belongs to the metallurgical production equipment technical field.
Background technology
The tapping hole of slagging tap of titanium slag electric arc furnaces is mainly used in deslagging and row's iron.During the titanium slag electric arc furnace smelting, titanium slag and molten iron be slagging tap and the tapping hole outflow from the furnace wall bottom discontinuously.The existing tapping hole of slagging tap is formed by magnesite-chrome brick and corundum-mullite brick masonry respectively.Owing to slag tap when tapping a blast furnace, the temperature of titanium slag and molten iron respectively up to 1800 ℃ and 1650 ℃ about, titanium slag has extremely strong erosiveness under this temperature, the erosiveness of molten iron is stronger, and the resistance to thermal shocks of magnesite-chrome brick and corundum-mullite brick is poor, is at high temperature very easily corroded by titanium slag and molten iron, therefore the tapping hole of slagging tap is shorter service life, about average out to 15 heats, not only repair and maintenance difficulty, and cost height.
The utility model content
Technical problem to be solved in the utility model is: the iron construction of slagging tap that a kind of titanium slag electric arc furnaces of long service life is provided.
For solving the problems of the technologies described above the technical scheme that adopts be: a kind of iron construction of slagging tap of titanium slag electric arc furnaces, comprise the duct main body, also comprise the high temperature resistant erosion resistant mouth and go out embolum of slagging tap, mouth is provided with slag notch slagging tap, tapping hole is set going out embolum, slag tap mouth and going out on two ports of export that embolum is installed in respectively the duct main body, slag notch and tapping hole all are communicated with the duct main body.
Further be that the vertical height of slag notch is greater than the vertical height of tapping hole.
The optimal way of such scheme is: the vertical range of slag notch and tapping hole is 350 ㎜～450 ㎜.
Further be, the slag notch that arranges at the mouth of slagging tap is two, also is two going out the tapping hole that embolum arranges, and the line of the centerline points of two slag notches is parallel to the line of the centerline points of two tapping holes.
Further be that the diameter of slag notch is greater than the diameter of tapping hole.
Further be that the duct main body is formed by magnesite-chrome brick and corundum-mullite brick masonry.
The beneficial effects of the utility model are: by the high temperature resistant erosion resistant mouth and go out embolum of slagging tap is installed respectively at the port of export of duct main body.Mouth is to be made by high temperature resistant erosion resistant material with going out embolum owing to slag tap, like this, in use, just can resist the erosion of high temperature titanium slag, molten iron, thereby effectively prolong the titanium slag electric arc furnaces, particularly the titanium slag electric arc furnaces is slagged tap mouth and the service life that goes out embolum, thereby saves maintenance cost and operating cost.The described high temperature resistant erosion resistant mouth and to go out embolum can be by high temperature resistant erosion resisting of slagging tap, and cheap carborundum, graphite powder and silica flour material are built separately and are formed; Also can be that carborundum, graphite powder and silica flour material are passed through manual integrated poured moulding at the port of export of duct main body.
Description of drawings
Fig. 1 is the structure cutaway view of duct main body of the iron construction of slagging tap of a kind of titanium slag electric arc furnaces of the utility model;
Fig. 2 is a left side (right side) half side view of the iron construction of slagging tap of a kind of titanium slag electric arc furnaces of the utility model.
Be labeled as among the figure: duct main body 1, the mouth 2 of slagging tap, go out embolum 3, slag notch 4, tapping hole 5.
The specific embodiment
The iron construction of slagging tap of the titanium slag electric arc furnaces of a kind of long service life of providing of the utility model as shown in Figure 1 and Figure 2.The iron construction of slagging tap of described titanium slag electric arc furnaces comprises duct main body 1, also comprise the high temperature resistant erosion resistant mouth 2 and go out embolum 3 of slagging tap, mouth 2 is provided with slag notch 4 slagging tap, tapping hole 5 is set going out embolum 3, slag tap mouth 2 and going out on two ports of export that embolum 3 is installed in respectively duct main body 1, slag notch 4 and tapping hole 5 all are communicated with duct main body 1.Mouth 2 is to be made by high temperature resistant erosion resistant material with going out embolum 3 owing to slag tap, like this, in use, just can resist the erosion of high temperature titanium slag, molten iron, thereby effectively prolong the titanium slag electric arc furnaces, particularly prolong the service life that the titanium slag electric arc furnaces is slagged tap mouth 2 and gone out embolum 3, thereby save maintenance cost and operating cost.The described high temperature resistant erosion resistant mouth 2 and to go out embolum 3 can be by high temperature resistant erosion resisting of slagging tap, and cheap carborundum, graphite powder and silica flour material are built separately and are formed; Also can be that carborundum, graphite powder and silica flour material are passed through manual integrated poured moulding at the port of export of duct main body 1.Simultaneously, owing to slag tap mouth 2 and go out embolum 3 can high temperature resistant anti-erosion, can also play insulation effect to magnesite-chrome brick and corundum-mullite brick, thereby greatly slow down the damage that magnesite-chrome brick and corundum-mullite brick cause because of rapid heat cycle, and then further make slag tap mouth and the life that goes out embolum.
In the above-mentioned embodiment, for the ease of not affecting row's iron when the deslagging, simultaneously, and the mouth 2 and go out the inspection and maintenance of embolum 3 of being convenient to slag tap, the vertical height of institute's slag notch 4 is greater than the vertical height of tapping hole 5; And best difference in height is 350 ㎜～450 ㎜; The slag notch 4 that arranges at the mouth 2 of slagging tap is two, also is two at the tapping hole 5 that goes out embolum 3 settings, and the line of the centerline points of two slag notches 4 is parallel to the line of the centerline points of two tapping holes 5; And the diameter of slag notch 4 is greater than the diameter of tapping hole 5.
