Abstract
The invention discloses a kind of prefabricated part of embedded swing nozzle, including prefabricated part body, the prefabricated part body end surface shape is arc-shaped corresponding with swing nozzle.One end end face of the prefabricated part body is in curved bottom one step of outstanding formation.The height of the step is the half of prefabricated part body floor height.The prefabricated part body bottom surface is provided with two grooves for running through both sides end face.The groove is shaped as triangle.The good swing nozzle prefabricated component of high temperature sintering is embedded into swing nozzle position by the present invention, then upper material is poured into a mould around it makes swing spout form composite construction, and one end end face of prefabricated part body is poured into a mould by castable in the step of curved bottom and covered, make being integrated into a whole for prefabricated component and swing nozzle.With energy-conservation, it is durable and easy to maintenance the advantages of.
Description
Technical field
The present invention relates to a kind of swing nozzle prefabricated component.
Background technology
Big-and-middle-sized one iron mouth of blast furnace need to contain two or three of hot-metal bottles, and molten iron can not be interrupted when tapping a blast furnace, and the ditch body of oscillating channel can
Hot-metal bottle is changed to tilt to swing within the specific limits, oscillating channel is generally 1.5 meters or so away from iron runner grease head highness, molten iron pair
The impact of oscillating channel belly is very big.Much use integrated poured swing nozzle in the prior art, its technical disadvantages is as follows：1, baking
Time is grown, and cured effect is bad.Both ends can not be covered tightly completely because swing nozzle both ends open, when baking.Allow to
A little is covered, the temperature of the baking of mouthpiece still has larger gap compared with oscillation center, causes mouthpiece baking incomplete, so as to lead
Castable various aspects of performance is caused to reduce.It is as far as possible better to want baking, that just has to extend baking time, but consumes coal gas, increases
Add baking cost.2 service lifes are short.Swing nozzle easily cracks due to expanding with heat and contract with cold frequently.Once crack, such as
Fruit does not have material to be obstructed, and will extend.Molten iron erosiveness is strong simultaneously, causes Crack Extension to accelerate, last until burning
Swing nozzle.Oscillating channel of the prior art also has using resistance to using having at the big position of tap drain melting loss or oscillating channel impact site
Fiery prefabricated component combined and alternatively is built by laying bricks or stones, and fire-resistant prefabricated member is combined together with swinging mouth with castable refractory cast, but is not had
Prefabricated component is designed exclusively for swing nozzle.
The content of the invention
The technical problems to be solved by the invention, which are just to provide a kind of swing nozzle prefabricated component, makes prefabricated component and swing nozzle
Be integrated into a whole, safe, durability is good.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of prefabricated part of embedded swing nozzle, its
It is characterised by：Including prefabricated part body, the prefabricated part body end surface shape is arc-shaped corresponding with swing nozzle.
Preferably, one end end face of the prefabricated part body is in curved bottom one step of outstanding formation.It is described
The height of step is the half of prefabricated part body floor height.
Preferably, the prefabricated part body bottom surface is provided with two grooves for running through both sides end face.The shape of the groove
Shape is triangle.In order to castable with chelating stronger between prefabricated component together, formed one it is similar overall.
Preferably, the heteropleural end face that the prefabricated part body sets the end face of step is inclined as one from bottom to top-direction
Oblique inclined-plane.
The present invention by the good swing nozzle prefabricated component of high temperature sintering by adopting the above-described technical solution, be embedded into swing mouth
Oral area position, upper material is then poured into a mould around it makes swing spout form composite construction, and one end end face of prefabricated part body
Poured into a mould and covered by castable in the step of curved bottom, make being integrated into a whole for prefabricated component and swing nozzle.It is beneficial to knot
Fruit is：
1, energy-conservation.The use of prefabricated part of embedded swing nozzle after high temperature sintering, shorten baking time 2 days or so, save energy
Source consumes, and reduces baking cost.
2, it is durable.Integrated poured swing nozzle iron is repaiied once at 40,000 tons with regard to needs, pre- using embedded swing nozzle
After product, lead to iron to 80,000 tons, just need to change once.Improve iron and reach 100%.Durable main cause has two：When
Swing spout prefabricated component have already passed through high temperature sintering possess higher intensity can be resistant to molten iron discharging first flush；Second, swing
Stem bar prefabricated component can prevent Crack Extension, increase the service life.
3, it is easy to maintenance.Only need to take out swing nozzle prefabricated component during maintenance, be put into new prefabricated component；Then in its week
Construction castable is enclosed, it is bonded together with original liner body, then can lead to iron with big fire 3 hours of baking.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description：
Fig. 1 is the structural representation of one end end face of the present invention；
Fig. 2 is the side view of the present invention；
Fig. 3 is the top view of the present invention.
Embodiment
As shown in Figure 1 to Figure 3, it is a kind of embodiment of prefabricated part of embedded swing nozzle of the present invention, including prefabricated component sheet
Body 1, the end surface shape of prefabricated part body 1 are arc-shaped corresponding with swing nozzle, one end end face of the prefabricated part body 1
In curved bottom one step 2 of outstanding formation.The height of the step 2 for the floor height of prefabricated part body 1 two/
One.The bottom surface of prefabricated part body 1 is provided with two grooves 3 for running through both sides end face.The groove 3 is shaped as triangle.
The prefabricated part body sets the heteropleural end face 4 of the end face of step as one from bottom to the inclined inclined-plane of top-direction.
The manufacturing process of swing nozzle prefabricated component of the present invention is：Branch mould → stirring cast → vibratory compaction → health 24 is small
When → demoulding → 1000 DEG C baking → packaging → finished product.
