Abstract
The utility model discloses an iron runner residual iron hole for discharging blocked residual iron, which belongs to the technical field of blast furnace tapping. The residual iron hole comprises a cone-shaped hole and a column-shaped hole, the column-shaped hole is communicated with the cone top end of the cone-shaped hole, corundum silicon carbide blocking materials are filled in the column-shaped hole, and cone-shaped prefabricated pieces matched with the shape of the cone-shaped hole is filled in the cone-shaped hole. The iron runner residual iron hole for discharging the blocked residual iron can discharge a blocked residual iron hole fast and safely, shortens residual iron discharging time from half an hour to ten minutes, materials including drills, thin-wall iron pipes are not consumed, and ferric oxide yellow smoke can not be generated by burning the residual iron hole through blowing oxygen.
Description
Technical field
The utility model relates to a kind of residual iron of iron runner hole that is used to put stifled residual iron, belongs to the blast furnace casting technical field.
Background technology
Handle in the residual iron of iron runner hole is a great problem in each ironworks always, and common mode is the mode that oxygen blast hole burning or machinery are punchinged at present.The mode that the oxygen blast hole burning is to use the thin-walled iron pipe to blow industrial oxygen is burnt the original material of blocking up in position, residual iron hole; Misoperation caused the reaming of residual iron mouth or produces special-shaped residual iron hole when this mode may be owing to perforate; Cause cramming once more unreal, can cause leaking iron when serious.And the Kong Ze that leaves through mechanical perforate mode is comparatively regular; But sizable defective is also arranged, because more than under the hot soak condition, it is fairly obvious that the refractory materials burning is melted the agglomerating phenomenon altogether; Especially near the position of molten iron; Sintering is more thorough, and drill bit is at high temperature often powerless in the face of the agglomerating refractory materials when holing in this case, and drill bit consumption is very big.So it is very necessary to seek a kind of perforate mode quickly and easily.
The utility model content
The utility model provides a kind of residual iron of iron runner hole that is used to put stifled residual iron, and this residual iron hole is a kind of multi-layer compound structure, realization perforate and plug-hole operation that can be safely and fast.
The utility model has been taked following technical scheme.The utility model comprises tapered hole and cylindrical hole two portions, and said cylindrical hole is connected with the vertex of a cone end of tapered hole, is filled with the corundum carborundum matter material of blocking up in the said cylindrical hole, is filled with the taper prefab that adapts with tapered bore profile in the said tapered hole.Said taper preform surfaces is provided with the carbonaceous mud layer.Be provided with the reinforcing bar inner core in the said taper prefab, the awl bottom is provided with draw ring.
In terms of existing technologies, the utility model can fast and safely be put stifled residual iron mouth, will put the residual iron time by shortening to 10 minutes half a hour, and do not consume drill bit in the process, material such as thin-walled iron pipe, can not produce the red stone tobacco that residual iron hole is burnt in oxygen blast yet.

Embodiment
For above-mentioned purpose, the feature and advantage that make the utility model can be more obviously understandable, the utility model is done further detailed explanation below in conjunction with accompanying drawing and embodiment.
The utility model comprises tapered hole 1 and cylindrical hole 2 two portions, and cylindrical hole 2 is connected with the vertex of a cone end of tapered hole 1, is filled with the corundum carborundum matter part 4 of blocking up in the cylindrical hole 2, is filled with the taper prefab 3 that adapts with tapered hole 1 shape in the tapered hole 1.Taper prefab 3 surfaces are provided with carbonaceous mud layer 5.Be provided with reinforcing bar inner core 6 in the taper prefab 3, the awl bottom is provided with draw ring 7.
Embodiment:
The utility model is a kind of residual iron of the iron runner hole that can put residual iron fast, and this residual iron mouth passes the iron runner sidewall, is is main composite structure with the taper.Pyramidal structure uses when building die modeling to form; Use funnel shaped residual iron punch die when building iron runner, make residual iron hole constitute the moulding that designs, the residual iron hole that is configured to is divided into two sections; As shown in Figure 1; One section is the tapered hole 1 near the pyramidal structure outer wall of iron runner outer wall, and an end diameter of tapered hole 1 is about 400mm, and the other end diameter is about 100mm.Another section is the cylindrical hole 2 near the equal aperture of iron runner inner wall section, and cylindrical hole 2 is connected with vertex of a cone end in the tapered hole 1, and cylindrical hole 2 is the circular hole of long 150mm, diameter 100mm.In tapered hole 1, be provided with taper prefab 3, in cylindrical hole 2, be filled with corundum carborundum matter blocking piece 4.Adopt taper prefab 3 to block tapered hole 1 when blocking up, the shape of taper prefab 3 and tapered hole 1 shape adapt, and an end diameter of taper prefab 3 is about 400mm, and the other end diameter is about 100mm.Cylindrical hole 2 parts in isometrical duct then use corundum carborundum matter mould material to cram; Because corundum carborundum matter mould material easy-sintering not under this environment, so and have that to chisel residual iron comparatively easily under the situation that good corrosion resistance can guarantee not leak iron empty.As shown in Figure 2, present embodiment uses the taper prefab 3 of casting material prefabricated band reinforcing bar inner core 6, and the diameter of reinforcing bar is 15mm, and the awl bottom face of taper prefab 3 is provided with draw ring 7.
After pour mass is built and is finished; At first use the corundum carborundum matter part 4 of blocking up to cram cylindrical hole 2 parts; This corundum carborundum matter part 4 of blocking up is to use corundum carborundum matter mould material to fill moulding, then uses carbonaceous mud to smear taper prefab 3 surfaces, forms carbonaceous mud layers 5 on taper prefab 3 surfaces; Again taper prefab 3 is filled in the tapered hole 1 in residual iron hole, and compacting.
During perforate; Use manpower or machinery to extract the taper prefab of blocking up,, can use the more or less freely brill of hawkbill to open isometrical duct part because corundum carborundum matter is blocked up and expected not easy-sintering; Whole perforate process is estimated ten minutes, and the red stone tobacco that produces when not having the oxygen blast hole burning.
Taper prefab 3 uses the steel plate mould when making, and utilizes the cast of cleek mould material to process, and wherein rebar surface wraps up one deck 2mm plastics film, to alleviate metal and the inconsistent cracking problem that causes of the mould material coefficient of expansion.
More than a kind of residual iron of iron runner hole that is used to put stifled residual iron described in detail to the utility model provides; Used specific embodiment among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, part all can change on embodiment and range of application.In sum, this description should not be construed as the restriction to the utility model.
