Abstract
The invention discloses a prefabricated part of an embedded swing nozzle, which comprises a prefabricated part body. The end face of the prefabricated part body is in a shape of an arc corresponding to the swing nozzle; one end face of the prefabricated part body protrudes outward to form a step at the bottom of the arc; the height of the step is one second that of the bottom of the prefabricated part body; and two triangular grooves passing through the end faces on two sides are reserved at the bottom of the prefabricated part body. The high-temperature-sintered prefabricated part of the swing nozzle is embedded into the swing nozzle part; a pouring material is poured around the prefabricated part to form a composite structure of the swing nozzle; and the step at the bottom of the arc on one end face of the prefabricated part is covered by pouring the pouring material so that the prefabricated part and the swing nozzle are integrated. The prefabricated part of the invention has the advantages of energy conservation, durability and convenient maintenance.
Description
Technical field
The present invention relates to a kind of swing nozzle prefabricated component.
Background technology
Iron mouth of big-and-middle-sized blast furnace need be contained iron ladle two or three, molten iron can not be interrupted when tapping a blast furnace, the ditch body of swing ditch can tilt within the specific limits to swing and change iron ladle, and the swing ditch is generally about 1.5 meters apart from iron runner head height degree, and molten iron is very big to the impact of swing ditch belly.The integrated poured swing nozzle of a lot of employings in the prior art, its technical disadvantages is as follows: 1, storing time is long, and cured effect is not good.Because the swing nozzle both ends open can't cover two ends completely in the time of baking fully.Promptly allow to cover a little, the temperature of the baking of mouth mouth still has big gap than oscillation centre, causes the baking of mouth mouth not exclusively, thereby causes the mould material various aspects of performance to reduce.It is better as far as possible to want baking, and that just must prolong storing time, but consumes coal gas, increases the baking cost.2 work-ing lifes are short.Swing nozzle is easy to generate crackle owing to expand with heat and contract with cold frequently.In case crack,, will expand if there is not material to intercept.The molten iron erosional competency is strong simultaneously, causes crack propagation to be quickened, at last until burning swing nozzle.Swing ditch of the prior art also has employing to have fireproof prefabricated combined and alternatively to build by laying bricks or stones in tap drain melting loss big position or the employing of swing ditch impact site, and make fireproof prefabricated to combine, but do not design prefabricated component for swing nozzle specially with the swing mouth with refractory castable cast.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of swing nozzle prefabricated component makes prefabricated component as a whole with combining of swing nozzle, safe, and wearing quality is good.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of prefabricated part of embedded swing nozzle is characterized in that: comprise prefabricated part body, described prefabricated part body end surface shape is corresponding with swing nozzle circular-arc.
As preferably, an end end face of described prefabricated part body is outwards outstanding in the circular arc bottom to form a step.The height of described step is 1/2nd of a prefabricated part body bottom surface height.
As preferably, described prefabricated part body bottom surface is provided with two grooves that run through the both sides end face.Described groove be shaped as trilateral.In order to be that mould material is followed stronger being sequestered in together between the prefabricated component, form a similar integral body.
As preferably, the heteropleural end face that described prefabricated part body is established the end face of step be one by the bottom to inclined-plane that top-direction tilts.
The present invention is owing to adopted technique scheme, the swing nozzle prefabricated component that high temperature sintering is good is embedded into the swing nozzle position, mould material makes swinging flow jet form composite structure in cast around it then, and the step of an end end face of prefabricated part body in the circular arc bottom covered by the mould material cast, makes prefabricated component as a whole with combining of swing nozzle.Its useful result is:
1, energy-conservation.The use of the prefabricated part of embedded swing nozzle behind the high temperature sintering was shortened storing time about 2 days, and save energy consumption reduces the baking cost.
2, durable.Integrated poured swing nozzle iron influx just need be repaiied once at 40,000 tons, adopts after the prefabricated part of embedded swing nozzle, and ten thousand tons of logical iron to 8 just need to change once.Improve iron influx and reach 100%.Durable major cause has two: one, and the swinging flow jet prefabricated component possesses higher intensity through high temperature sintering can be born out the initial stage of molten iron and wash away; The 2nd, the swinging flow jet prefabricated component can prevent crack propagation, increases the service life.
3, easy to maintenance.Only the swing nozzle prefabricated component need be taken out during maintenance, put into new prefabricated component; In its mould material of constructing, itself and original lining body were bonded together on every side then, can lead to iron in 3 hours with the big fire baking then.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is further described:
Fig. 1 is the structural representation of an end end face of the present invention;
Fig. 2 is a side-view of the present invention;
Fig. 3 is a vertical view of the present invention.
Embodiment
As shown in Figure 1 to Figure 3, embodiment for a kind of prefabricated part of embedded swing nozzle of the present invention, comprise prefabricated part body 1, described prefabricated part body 1 end surface shape is corresponding with swing nozzle circular-arc, and an end end face of described prefabricated part body 1 is outwards outstanding in the circular arc bottom to form a step 2.The height of described step 2 is 1/2nd of prefabricated part body 1 a bottom surface height.Described prefabricated part body 1 bottom surface is provided with two grooves 3 that run through the both sides end face.Described groove 3 be shaped as trilateral.The heteropleural end face 4 that described prefabricated part body is established the end face of step be one by the bottom to inclined-plane that top-direction tilts.
The making processes of swing nozzle prefabricated component of the present invention is: mould → stirring cast → vibratory compaction → 24 hours → demoulding of health → 1000 ℃ of baking → packing → finished products.
