Abstract
The utility model relates to a kind of blast furnace metallurgy incidence mounts, including ejection or injection apparatus and set on ejection or the injection component of injection apparatus discharge port, injection component is set to above trough, injection component includes bending part, when so that the powdery or block material that spray into trough entering trough, incident path is in the liquid level point of intersection tangent line of trough and the liquid level normal angle of trough less than 60 °.The utility model can save acceleration and be taken up space, and be sufficiently mixed solid material and molten iron further；Simultaneously avoid accelerating it is excessive, solid material impact or destroy trough refractory material the phenomenon that occur.Production cost is reduced, resource utilization is improved, improves economic results in society.Safety and environmental protection, relieve has unfavorable factor in the prior art, but also solid material utilization rate is more abundant, reduces production cost.
Description
Technical field
The utility model relates to a kind of incidence mount, especially a kind of blast furnace metallurgy incidence mount belongs to field of metallurgy.
Background technique
Since blast furnace metallurgy is increasingly paid attention to by Ferrous Metallurgy researcher, the qualification of iron-smelting process production molten iron is improved
Rate accomplishes that the advance for improving blast furnace ironmaking has become the emphasis of blast fumance to improve blast furnace Effective capacity.It is de-
Silicon, desulfurization, dephosphorization (referred to as three de-) depend primarily on the mixing of the pulvis and molten iron of entrance in pretreated abundant react of molten iron
It degree and residence time, is easy to be absorbed by the scum above molten iron there are pulvis and package, and molten iron mixed effect is bad asks
Topic.Dephosphorization, desiliconization and desophorization for hot metal widely uses torpedo tank car at present, although this method using effect is preferable, in production cost controlling party
It there is a problem that certain in face.
Utility model content
In order to solve the above-mentioned technical problem, the present invention is de- from powder or blocks of solid metalliferous effective three or increases iron or tune
It requires preferably to mix with molten iron when warm material (hereinafter referred to as solid material) sprays into trough, and pulvis is avoided to contact with scum
From the point of view of, propose a kind of blast furnace metallurgy incidence mount.
The technical solution of the utility model is as follows:
A kind of blast furnace metallurgy incidence mount, including ejection or injection apparatus and set on ejection or injection apparatus discharge port
Injection component, injection component are set to above trough, and injection component includes bending part, so that spraying into the powdery or block in trough
When shape material enters trough, incident path is less than in the liquid level point of intersection tangent line of trough and the liquid level normal angle of trough
60°。
Further, injection apparatus includes taper tank body, the feeding inlet above taper tank body, is set under taper tank body
Injection pipe, air supply pipe and several gas control valves of side, gas control valve are set on air supply pipe, with the blow vent of taper tank body,
Taper tank body lower end is connected to injection pipe, and ejector pipe is connect with injection pipe.
Further, the angle of bending part is 100-150 °.
Further, injection component being capable of any bending.It is made of existing high-temperature-resistant flexible material.
Further, blow vent, air supply pipe, be equipped with pressure gauge on several gas control valves.
Compared with prior art, the utility model has the following beneficial effects:
1, the speed when solid material after the utility model accelerates enters molten iron level, which is greater than, uses equal height condition
It is lower using gravity accelerated method obtain speed solid material, can save acceleration taken up space, make solid material and molten iron into
One step is sufficiently mixed；Simultaneously avoid accelerating it is excessive, solid material impact or destroy trough refractory material the phenomenon that occur.
2, the solid material that the utility model is flown into trough enters molten iron or containing multi-motions or non-fortune such as slag irons
Dynamic fluid incident path, less than 60 °, makes full use of the characteristic of injection steel pipe in liquid level point of intersection tangent line and liquid level normal angle, adjusts
Whole solid material entry angle improves resource utilization to reduce production cost, improves economic results in society.
3, safety and environmental protection, relieve has unfavorable factor in the prior art, but also solid material utilization rate is more abundant, drop
Low production cost.
4, replaceable solid after injection member forward end scaling loss, it is easy to operate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, the technical solution in the present embodiment is carried out it is clear, complete
Site preparation description, it is clear that described embodiment is only the example to a part of example of the utility model, rather than whole.Base
In the embodiments of the present invention, those of ordinary skill in the art institute obtained under that premise of not paying creative labor
There are other embodiments, fall within the protection scope of the utility model.
As shown in Figure 1, the blast furnace metallurgy incidence mount of the present embodiment, including injection apparatus 1 and go out set on injection apparatus 1
The ejector pipe 2 of material mouth, ejector pipe 2 are set to tapered 3 top of trough, and ejector pipe 2 includes bending part, so that spraying into trough
In powdery or block material when entering trough, incident path is in the liquid level point of intersection tangent line of trough and the liquid level of trough
Normal angle is less than 60 °, in case material and the molten iron level direction projected, close to parallel, raw material is not easily accessible in molten iron, simultaneously
It may cause the waste of the risk and raw material in production.
Injection apparatus 1 includes taper tank body 1.2, the feeding inlet 1.1 above taper tank body 1.2, is set to taper tank body
Injection pipe 1.4, air supply pipe 1.5 and first gas regulating valve 1.6, the second gas regulating valve 1.7, third gas tune of 1.2 lower sections
Save valve 1.8, three gas control valves are set on air supply pipe 1.5, and 1.4 one end of injection pipe is horizontally disposed, respectively with taper tank body
Blow vent, taper tank body lower end 1.3 are connected to the horizontal segment of injection pipe 1.4, and ejector pipe 2 is connect with injection pipe 1.4.Ejector pipe 2
It being capable of any bending.The angle of bending part is 100-150 °.Blow vent, air supply pipe are equipped with pressure on several gas control valves
Table adjusts powder flow rate.
After powdery or block-like solid material are accelerated by injection or ejection, into the trough for having molten iron, change
Solid material enters the entrances state of blast-melted ditch, the residence time increase for contacting solid material with molten iron, mixing journey
Degree increases, to adapt to improve three requirements that are de-, increasing iron, temperature adjustment efficiency, to reduce the usage amount of solid material.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
