Abstract
Stifled iron notch device and preparation and application under a kind of blast furnace taphole state of emergency belong to before State of Blast Furnace technical field of tapping a blast furnace.Stifled iron notch device is made of iron notch opening drill and conical molten iron ingot bar.Iron notch opening drill is got out during preparation；Molten iron is poured into and molding is condensed in mould, obtains conical molten iron ingot bar by the pre-production cone mould in sand drift；Before the solidification of conical molten iron ingot bar, iron notch opening drill is placed on ingot bar surface, condensation is bonded to single piece.Stifled iron notch device is mounted on opening driver drilling rod during use, stifled iron notch device is sent into duct and pushes up reality；Then reversion opening driver drilling rod, unloads stifled iron notch device, stands 20 ± 5min；Drilling rod is finally exited into iron mouth pore passage.The advantage is that scene can quick Fabrication stifled iron notch device, can be sealed in the case of blast furnace not blowing-out stifled iron notch ensure blast fumance do not interrupt.
Description
Technical field
The invention belongs to technical field of tapping a blast furnace before State of Blast Furnace, stifled iron notch fills under more particularly to a kind of blast furnace taphole state of emergency
It puts and preparation and application.More particularly to the stifled iron notch device before a kind of State of Blast Furnace under stifled iron cement big gun fault condition, make blast furnace
Stokehold with pressure can be blocked up, and stifled iron notch device is simple, easy to operate.
Background technology
Blast furnace casting configuration open device (tapping machine) and equipment of blocking up (clay gun), in normal productive process, when providing
In, it needs to be carried out boring the operation of iron mouth with opening machine equipment, liquid molten iron and clinker be discharged, when iron needs to use clay gun after rolling
Iron mouth is blocked fire clay press-in iron mouth pore passage by equipment, is opened so as to complete normal iron mouth, stifled work, is ensured that blast furnace is continuously given birth to
Production.
And when tapping-hole clay gun breaks down, after stifled iron notch can not being sealed, since blast furnace is all operation with high pressure, occurrence of equipment event
After barrier, blast furnace is needed to carry out work of manually blocking up after changing normal pressure even blowing-out, blast fumance band of discontinuance is caused to carry out larger economic damage
It loses, while safety of workers composition great threat, labor intensity can also be greatly increased.
Invention content
The purpose of the present invention is to provide stifled iron notch device and preparation and application under a kind of blast furnace taphole state of emergency,
It solves the problems, such as to change under blast furnace tapping-hole clay gun failure after normal pressure even blowing-out using manually blocking up.Make the process of blocking up simple, fast
It is prompt, safe efficient, ensure that blast fumance does not interrupt.
Stifled iron notch device under a kind of blast furnace taphole state of emergency is made of iron notch opening drill 1 and conical molten iron ingot bar 2.
Iron notch opening drill 1 is bonded together on conical molten iron ingot bar 2 by condensation.The specification of iron notch opening drill 1 is DN45,
DN50, DN60, DN70 or DN80；The specification of conical molten iron ingot bar 2 is corresponding with drill for tapping machine specification, is DN55 ± 2, DN60
± 2, DN70 ± 2, DN80 ± 2 or DN90 ± 2.
The preparation method of stifled iron notch device, is as follows under a kind of blast furnace taphole state of emergency：
1st, iron notch opening drill 1 is got out；
2nd, the pre-production cone mould in sand drift, cone bottom diameter increase by 10 ± 2mm by the specification of iron notch opening drill 1,
Deep 100 ± the 10mm of circular cone；
3rd, molten iron is poured into the mould that pre-production is good in step 2 condensation molding to get to conical molten iron ingot bar 2；
4th, before the solidification of conical molten iron ingot bar 2, iron notch opening drill 1 is placed on ingot bar surface, slighter compress 2mm is allowed to
Single piece is bonded to the condensation of conical molten iron ingot bar 2.
The application method of stifled iron notch device, is as follows under a kind of blast furnace taphole state of emergency：
1st, the stifled iron notch device made is mounted on opening driver drilling rod, starts opening machine equipment by the stifled iron notch device
It is sent into duct and pushes up reality；
2nd, opening driver drilling rod is then inverted, the stifled iron notch device is unloaded and holding position stands 20 ± 5min；
3rd, drilling rod is finally exited into iron mouth pore passage.
It is an advantage of the current invention that scene can quick Fabrication stifled iron notch device, can not block up feelings in stemming failure of blocking up
Under condition, the stifled iron notch device of making is loaded onto using tapping machine, stifled iron notch can be sealed in the case of blast furnace not blowing-out, compared to artificial
Whole process of blocking up is simple, quick, safe efficient, ensures that blast fumance does not interrupt.
