Description
Technical field
The utility model belongs to blast furnace ironmaking equipment technical field, and in particular to a kind of blast furnace ironmaking skimming device.
Background technique
Blast furnace ironmaking is to apply coke, natural rich lump ore and sinter and pellet and flux in vertical reactor blast furnace
The method of continuous production liquid pig iron.It is the important link of modern steel production.
After blast furnace refinery, hot metal flow enters sow, in sow, the skimming devices such as big lock is usually arranged and carry out pushing off the slag,
In the process, molten iron temperature is up to 1450-1570 °C, and big lock is continually washed away by high temperature liquid iron and slag repeatedly, ground
Damage and corrosiveness, operating condition is quite severe, especially the corrosion function that is subject to of the lower part great Zha castable more very, for a long time
Erosion under, the lower part great Zha and furrow bank lower part castable melting loss, and then big lock prefabricated component is caused to loosen, fall off, so as to cause big
Lock service life reduces.
Utility model content
To solve the above-mentioned problems, the utility model proposes a kind of blast furnace ironmaking skimming device, specific technical solutions
It is as follows:
A kind of blast furnace ironmaking skimming device comprising: play the big lock prefabricated component of pushing off the slag and to be cast in big lock prefabricated
Part periphery, the big lock castable for fixing big lock prefabricated component,
The big lock prefabricated component is provided with disconnecting prevention structure, and the disconnecting prevention structure is set in big lock castable.
Further, the disconnecting prevention structure is anticreep protrusion.
In one preferred scheme, the anticreep protrusion be long 180-200mm, width 180-200mm, thick 80-120mm dash forward
It rises.
The utility model has the beneficial effects that:
The utility model improves big lock preform structure, increases disconnecting prevention structure, and disconnecting prevention structure is embedded in big lock
In castable, the span of big lock prefabricated component is increased, while making the combination of big lock prefabricated component and castable even closer, effectively
Big lock prefabricated component loose phenomenon caused by furrow bank and big lock cast bed of material lower part melting loss is reduced, service life is increased.

Specific embodiment
With reference to the accompanying drawing and the embodiments of the present invention make a kind of blast furnace ironmaking skimming device of the utility model
Further details of explanation.
Molten blast furnace molten iron flows through the process of sow, as shown in figure 5, sow bottom is disposed with steel from top to bottom
Shell 6, clay brick 8, main iron runner pouring material 7, are molten iron channel 3 above castable 7, and molten iron enters sow through blast furnace iron notch 5
Molten iron channel 3,3 top of molten iron channel is provided with skimming device and slag notch 4, and the clinker in molten iron stops heap through skimming device
Product, is discharged by slag notch 4.
Traditional blast furnace ironmaking skimming device is as shown in Figure 1 and Figure 2, and skimming device is big lock shape comprising plays pushing off the slag and makees
Big lock prefabricated component 1 and it is cast in big lock prefabricated component periphery, the big lock castable 2 for fixing big lock prefabricated component, big lock
Big lock prefabricated component is fixed on 3 top of molten iron channel by castable 2, and in the course of work, big lock is repeatedly continually by high temperature liquid iron
With the washing away of slag, wear and corrosiveness, operating condition is quite severe, and the erosion that especially lower part great Zha castable is subject to is made
With more very, under prolonged corrode, the lower part great Zha castable melting loss, and then big lock prefabricated component is caused to loosen, fall off, to lead
Big lock service life is caused to reduce.
The utility model has carried out Curve guide impeller to skimming device, and as shown in Figure 3, Figure 4, the big lock prefabricated component is provided with
Disconnecting prevention structure 101, the disconnecting prevention structure are set in big lock castable and furrow bank castable.The disconnecting prevention structure 101 is preferably
Anticreep protrusion.In one preferred scheme, the anticreep protrusion be long 180-200mm, width 180-200mm, thick 80-120mm's
Protrusion.
Disconnecting prevention structure is embedded in big lock castable and furrow bank castable, is increased the span of big lock prefabricated component, is made simultaneously
The combination of big lock prefabricated component and castable is even closer.During Practical Project, even if invading of being subject to of the lower part great Zha castable
Erosion acts on melting loss, and under the action of disconnecting prevention structure 101, big lock prefabricated component will not generate loose phenomenon, increases service life.
It is all made according to the patent scope of the utility model the foregoing is merely the better embodiment of the utility model
Equivalent changes and modifications should all belong to the covering scope of the utility model.
