Abstract
The invention discloses a blast furnace iron notch blocking device in an emergency state as well as preparation and using methods of the blast furnace iron notch blocking device in the emergency state and belongs to the technical field of blast furnace cast house tapping. The iron notch blocking device comprises an iron notch drill bit and a conical molten iron ingot. When the iron notch blocking device is prepared, the iron notch drill bit gets ready; a conical mould is manufactured in a sandpile in advance, molten iron is poured into the mould, and condensation formation is carried out to obtain the conical molten iron ingot; and before the conical molten iron ingot is solidified, the iron notch drill bit is placed on the surface of the ingot and is adhered to the ingot to form a whole piece in a condensation manner. When being used, the iron notch blocking device is installed on a tapping machine drill rod, is sent into a hole path and is compactly propped; then, the tapping machine drill rod is reversed, and the iron notch blocking device is unloaded for standing for 20 plus/minus 5min; and finally, the drill rod quits the iron notch hole path. The iron notch blocking device has the advantages that the iron notch blocking device can be rapidly manufactured in field and can block the iron notch under the condition without blowing out of a blast furnace so as to ensure non interruption of blast furnace production.
Description
Technical field
The invention belongs to technical field of tapping a blast furnace before State of Blast Furnace, stifled iron notch dress under more particularly to a kind of blast furnace taphole state of emergency
Put and preparation and application.More particularly to the stifled iron notch device blocked up under iron cement big gun fault condition before a kind of State of Blast Furnace, 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, in regulation
In, need to be carried out boring the operation of iron mouth with opening machine equipment, liquid molten iron and slag are discharged, when iron needs to use clay gun after rolling
Iron mouth is blocked by equipment by fire clay press-in iron mouth pore passage, is opened so as to complete normal iron mouth, is blocked up work, it is ensured that blast furnace is continuously given birth to
Produce.
And when tapping-hole clay gun breaks down, it is impossible to after sealing stifled iron notch, as blast furnace is all operation with high pressure, there is equipment event
After barrier, need blast furnace manually to be blocked up after changing normal pressure even blowing-out work, cause blast fumance to interrupt and bring larger economic damage
Lose, while also great threat, labour intensity can be constituted to safety of workers greatly increasing.
The content of the invention
It is an object of the invention to provide stifled iron notch device and preparation and application under a kind of blast furnace taphole state of emergency,
Adopt after solving the problems, such as to change normal pressure even blowing-out under blast furnace tapping-hole clay gun failure and manually block up.Make the process of blocking up simple, fast
It is prompt, safe efficient, it is ensured that blast fumance does not interrupt.
Stifled iron notch device under a kind of blast furnace taphole state of emergency, is made up of iron notch opening drill 1 and conical molten iron ingot bar 2.
Iron notch opening drill 1 is bonded together by condensation on conical molten iron ingot bar 2.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.
Under a kind of blast furnace taphole state of emergency, the preparation method of stifled iron notch device, comprises the following steps that：
1st, get out iron notch opening drill 1；
2nd, the pre-production cone mould in sand drift, cone bottom diameter presses the specification of iron notch opening drill 1 increases by 10 ± 2mm,
Deep 100 ± the 10mm of circular cone；
3rd, pour molten iron in step 2 condensation shaping in the good mould of pre-production, that is, obtain 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 into ingot bar surface, slighter compress 2mm is allowed to
Single piece is bonded to the condensation of conical molten iron ingot bar 2.
Under a kind of blast furnace taphole state of emergency, the using method of stifled iron notch device, comprises the following steps that：
1st, the stifled iron notch device made is arranged on opening driver drilling rod, starts opening machine equipment by the stifled iron notch device
Send into duct and push up reality；
2nd, opening driver drilling rod is subsequently inverted, unloads the stifled iron notch device and holding position stands 20 ± 5min；
3rd, drilling rod is exited into iron mouth pore passage finally.
It is an advantage of the current invention that scene can quick Fabrication stifled iron notch device, cannot block up feelings in stemming failure of blocking up
Under condition, the stifled iron notch device of making is loaded onto using tapping machine, can seal stifled iron notch in the case of blast furnace not blowing-out, compare artificial
Whole process of blocking up is simple, quick, safe efficient, it is ensured that blast fumance does not interrupt.
