Description
Technical field
The present invention relates to a kind of desulfurizing iron blowing slag-removing device, particularly a kind of molten iron for being related to desulfurization pretreatment field
Desulfurization blowing slag-removing device.
Background technology
After molten iron pretreatment, there is substantial amounts of desulfurization slag in hot-metal bottle, in order to avoid returning sulphur, prevent molten iron to be lost in, to lead to
Some means are crossed to remove these bits.Desulfurization is two molten iron pretreatment works that are separate and being closely connected again with skimming
Skill, sulfur removal technology determine the level of processing terminal molten iron sulfur-bearing, and skim, and is from molten iron by the high sulphur slag after desulfurization process
The important means of middle removal, it is to determine the principal element into stove sulphur total amount.Comparatively speaking, slag skimming process seems to excessively program control sulphur
It is even more important.If desulfurization product cannot be removed effectively, then good sulfur removal technology can not play one's part to the full, therefore use
Advanced slagging-off equipment is very necessary with reducing production cost to system control sulphur with technique.
In steel industry, liquid slag is skimmed, is just low typically by the position of hot-metal bottle tipping to slag removal device
Realized in the position at iron/slag interface.But common issue existing for Slagging-off device is slag removal device can not reach hot-metal bottle after
At the slag blanket of wall, so the bits only started around skimming gate could be pulled down quickly, it is decreased obviously the rate of skimming.For
Dregs are made ceaselessly to be flowed out with slag removal device, it is desirable to which in hot-metal bottle the bits of distant place have to move to the domain of walk of slag removal device
It is interior.
Although having long been known that the necessity skimmed, seldom talk about this science of skimming, take off slag operation more according to
By the intuition and experience of operator, rather than the application of science.As a result cause to skim ineffective, under converter oxidizing atmosphere,
The sulphur remained in slag is again introduced into molten iron, desulfurization is failed.
The content of the invention
It is high the invention provides a kind of stabilization of equipment performance, it is easy to safeguard and changes, the iron of desulfurized effect can be significantly improved
Water desulfurization blowing slag-removing device.
The present invention is desulfurizing iron blowing slag-removing device used by solving the above problems, including desulfurization air blow gun, work
Platform, through hole is provided with the workbench, the desulfurization air blow gun passes through from the through hole of workbench, desulfurization air blow gun
Connected with desulphurization system, insufflation channel, described insufflation channel one end and desulfurization air blow gun are provided with the desulfurization air blow gun
Table wall is connected, and the other end is connected with blowing pipe, and cutoff device is provided with the blowing pipe.
It is further, in addition to drag chain, the drag chain are connected with the top of desulfurization air blow gun.
Be further, when the desulfurization air blow gun is in desulfurization state, insert the depth of iron bath for hot-metal bottle with
Upper 100mm~400mm；When the desulfurization air blow gun is in desulfurization state, the depth of iron bath is inserted as below molten iron level
800mm~1000mm.
It is further that the cutoff device is blowing slag-removing function valve.
The beneficial effects of the invention are as follows：Using the desulfurizing iron blowing slag-removing device of the application, in hot metal pre process procedures
On the basis of original layout, structure is more reasonable, realizes blowing desulfurization and blowing slag-removing dual-use function, and phase is required to hall space
To not strict, while it is easy to maintenance and replacing to spray gun, stabilization of equipment performance is high, and air blowing auxiliary effect of skimming is good.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Parts, position and numbering in figure：Desulfurization air blow gun 1, workbench 2.The drag chain 4 of insufflation channel 3.
Embodiment
As shown in figure 1, desulfurizing iron blowing slag-removing device used by the application, including desulfurization air blow gun 1, workbench
2, through hole is provided with the workbench 2, and the desulfurization air blow gun 1 passes through from the through hole of workbench 2, desulfurization air blow gun
1 is connected with desulphurization system, and insufflation channel 3 is provided with the desulfurization air blow gun 1, and described one end of insufflation channel 3 is blown with desulfurization
The table wall connection of rifle 1, the other end are connected with blowing pipe, and cutoff device is provided with the blowing pipe.The present invention is original
Desulfurization rifle in integrate blowing slag-removing function, in the table wall of desulfurization air blow gun 1, one hole connected with insufflation channel 3 work can be set
For inflatable mouth, and inflatable mouth is set to be located at molten iron face certain depth once.Pressed gas is sent into insufflation channel 3 by blowing pipe,
Pressed gas sprays from the table wall of desulfurization air blow gun 1 again, realizes the function of blowing slag-removing.When needing blowing desulfurization, cutoff device
Close, desulfurization rifle realizes desulfurizing agent blowing desulfurization function by injection system；When blowing desulfurization terminates to need blowing slag-removing, spray
Blow desulphurization system is closed, and cutoff device is opened, and air-flow can enter desulfurization air blow gun 1 by insufflation channel 3, realize that air blowing is caught up with
Slag.
Also include drag chain 4, the drag chain 4 is connected with the top of desulfurization air blow gun 1.Operating personnel can be by dragging during use
Chain 4 drives desulfurization air blow gun 1 to move up and down, therefore the present invention uses drag chain 4 can be with the spout of flexible modulation desulfurization air blow gun 1 in iron
Depth in water, so as to further improve the effect of desulfurization and blowing slag-removing.When it is implemented, the both ends of drag chain 4 are fixed on work
Make on platform 2, the middle part of drag chain 4 is connected with the top of desulfurization air blow gun 1.
When the desulfurization air blow gun 1 is in desulfurization state, insert the depth of iron bath for hot-metal bottle above 100mm~
400mm；When the desulfurization air blow gun 1 is in desulfurization state, insert the depth of iron bath for 800mm below molten iron level~
1000mm.Air-blowing quantity is 50~60m during specific implementation3/h.The present invention passes through the desulfurization air blow gun 1 to both the above working condition
Position in iron bath is defined, and further increases the effect of desulfurization and blowing slag-removing.
The cutoff device is blowing slag-removing function valve.Cutoff device uses the form of valve, passes through the opening and closing of valve
To realize work(transformation of energy between desulfurization and blowing slag-removing.
Using the desulfurizing iron blowing slag-removing device of the application, on the basis of the original layout of hot metal pre process procedures, structure
More rationally, blowing desulfurization and blowing slag-removing dual-use function are realized, to hall space requirement relatively not strictly, while be easy to pair
The maintenance and replacing of spray gun, stabilization of equipment performance are high, and air blowing auxiliary effect of skimming is good.
