Abstract
The utility model discloses a take water-cooling pre-buried tubular sediment iron runner sealed apron changes the cast steel spare into by the welding component, and the wholeness of apron is strengthened greatly, and the apron surface is the plane, and "well" word check are cast out to inboard heating surface, not only play the strengthening rib effect, also play very big effect to reinforcing resistant material adhesive force. In addition, on the basis of keeping original labyrinth seal structure form, at the inside pre-buried condenser tube of apron body, the normal during operation of apron leads to water circulative cooling, and the effectual influence that reduces tapping channel high temperature to the apron lets the apron keep normal atmospheric temperature operating condition for a long time and avoids the deformation that the high temperature influence produced to effectively guarantee the sealing performance of apron, prolonged the life of apron.
Description
Technical Field
The utility model relates to a take pre-buried tubular sediment iron runner of water-cooling to seal up apron.
Background
The iron-making blast furnace can produce a large amount of smoke and dust in the tapping process and pollute the production field, so that steel enterprises can reduce the pollution of the production process to the environment in order to meet the requirement of clean production, and a sealing cover plate is additionally arranged on a slag iron runner. Because the cover plate is formed by welding steel structures, in practical application, the welding members are often subjected to thermal deformation, welding failure and frequent repair, and the normal use is influenced by the wavy deformation and large-area defect. Due to the manufacturing precision and deformation of the welding components, gaps between the cover plates are large, smoke and dust often emerge from the gaps between the cover plates, and a good sealing effect cannot be achieved.
SUMMERY OF THE UTILITY MODEL
For solving the defect that the sediment iron runner apron exists and not enough, the utility model discloses a take water-cooling pre-buried tubular sediment iron runner sealed apron changes the cast steel spare into by the welding component, and the wholeness of apron is strengthened greatly, and the apron surface is the plane, and "well" word check are cast out to inboard heated surface, not only play the strengthening rib effect, also play very big effect to reinforcing resistant material adhesive force. In addition, on the basis of keeping original labyrinth seal structure form, at the inside pre-buried condenser tube of apron body, the normal during operation of apron leads to water circulative cooling, and the effectual influence that reduces tapping channel high temperature to the apron lets the apron keep normal atmospheric temperature operating condition for a long time and avoids the deformation that the high temperature influence produced to effectively guarantee the sealing performance of apron, prolonged the life of apron.
The sealing cover plate is composed of a plurality of cover plate units which are connected with each other along the length direction of the slag iron runner and used for covering the slag iron runner, and is different from the cover plate units formed by welding components in the prior art, the cover plate units are all formed by steel castings, and the cover plate units are identical in shape.
Furthermore, a ceramic fiber blanket is paved on the steel surface of the cover plate unit, and a light heat-insulating fireproof spray coating is sprayed outside the ceramic fiber blanket.
Further, the cover plate unit is respectively combined with a plurality of slag iron runner embedded steel pieces arranged along the length direction of the slag iron runner, and a sealing structure is formed at the combination position.
Drawings
Fig. 1 is a cross-sectional view of a sealing cover plate of the present invention;
fig. 2 is a side sectional view of the sealing cover plate of the present invention;
fig. 3 is a partially enlarged schematic view of fig. 2.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
In the figure: 1-cover plate body, 2-cooling water pipe, and 3-reinforcing rib plate.
Examples
As shown in the figure, the water-cooled embedded pipe type slag iron runner sealing cover plate consists of a plurality of cover plate units which are mutually connected along the length direction of a slag iron runner; the whole cover plate unit is made of steel castings, the outer surface of the cover plate is a plane, and the heating surface on the inner side is cast with a 'well' -shaped grid; and a cooling water pipe 2 is embedded in the cover plate body 1.
And a ceramic fiber blanket is paved on the steel surface of the cover plate unit, and a light heat-insulating fireproof spray coating is sprayed outside the ceramic fiber blanket.
The first combination portion of the cover plate unit is respectively combined with a plurality of slag iron runner embedded steel pieces arranged along the length direction of the slag iron runner, and a sealing structure is formed at the combination position. Specifically, pre-buried steel spare is provided with the fourth joint portion, the fourth joint portion includes fourth horizontal part and fourth vertical part. Wherein the fourth horizontal portion extends horizontally outward from the sidewall of the slag iron runner along the width direction of the slag iron runner; a fourth vertical portion extending upwardly from the fourth horizontal portion, the fourth vertical portion being longer than the first vertical portion.
The lower surface of the first horizontal part of each cover plate unit is in contact with the upper surface of the fourth vertical part of the pre-buried steel piece of the iron slag runner corresponding to the lower surface of the first horizontal part of each cover plate unit, a gap is formed between the lower surface of the first vertical part of the first combining part and the upper surface of the fourth horizontal part of the pre-buried steel piece of the iron slag runner, and three seals are formed between the first combining part of each cover plate unit and the fourth combining part of the pre-buried steel piece of the side wall of the iron slag runner corresponding to the first combining part of each cover plate unit: a first seal formed at a contact surface between a lower surface of the first horizontal portion and an upper surface of the fourth vertical portion, the first seal being a rigid hard seal; a second seal formed at a gap between the lower surface of the first vertical portion and the upper surface of the fourth horizontal portion and sealed by cellucotton; and the third seal is formed between the first horizontal part and the slag iron runner side wall and is filled by asbestos packing.
