Abstract
The utility model discloses a refined steel ladle double-layer air brick. The refined steel ladle double-layer air brick comprises an air brick core (1), an iron sheet lining (2), an outer seating brick (3) and a breather pipe (4), and ventilating pores (10) are arranged on the air brick core (1). The refined steel ladle double-layer air brick is characterized in that a second layer iron sheet lining (5) is arranged on the outer side of the iron sheet lining (2), and a refractory material (6) is poured between the iron sheet lining (2) and the second layer iron sheet lining (5). According to the refined steel ladle double-layer air brick, the double-layer seal is formed so as to prevent liquid steel coming from craze position on the outer seating brick (3) from directly permeating into the iron sheet lining (2) of the air brick core (1), simultaneously when ventilating points of the outer layer iron sheet lining (5) occur to be ventilated, the inner layer iron sheet lining (2) forms a protecting layer so as to guarantee that air can normally enter into the steel ladle, and the blowing success rate of refining is guaranteed.
Description
Technical field
The air supply brick that uses on the metallurgy steel-making industry refining ladle that the utility model relates to is for the gas permeable brick from ladle bottom nitrogen blowing or argon gas.
Background technology
The gas permeable brick of at present metallurgy industry refining ladle use is made of gas permeable brick core 1, iron sheet lining 2, ectosome brick cup 3, ventpipe 4, offers ventilating slit 10 at gas permeable brick core 1.Air brick of steel ladle such as the CN2004201083253 patent disclosure.In use, because what ladle adopted is that mould brick is built by laying bricks or stones, and ectosome brick cup 3 is casting, may produce the cracking seam after ectosome brick cup 3 bakings of gas permeable brick, molten steel in the ladle can flow downward along the crack on the ectosome brick cup 3, cause the gas permeable brick iron sheet to serve as a contrast 2 middle and upper parts and produce local melting and gas leakage, lost the closed protective effect to gas after 2 fusings of iron sheet lining, gas also has portion gas to flow in the ladle by the crack on iron sheet lining 2 and the ectosome brick cup 3 simultaneously except flowing in the ladle from the ventilating slit 10 that gas permeable brick core 1 is offered; After simultaneously iron sheet lining 2 fusings, gas also can be by the fusing point reverse flow to Ladle Bottom, air-back after forming, cause tolerance deficiency in the ladle, to blow out effect bad or can't blow out at all and make, cause the interior molten steel of ladle to need ladle-to-ladle processing or degradation to use, reduced rhythm of production, cause production loss.
The utility model content
The purpose of this utility model is to improve for the shortcoming deficiency of above-mentioned prior art, provides a kind of simple for production, work reliability, the refining ladle gas permeable brick that security is good.
The utility model comprises that gas permeable brick core 1, iron sheet lining 2, ectosome brick cup 3, ventpipe 4 consist of, offer ventilating slit 10 at gas permeable brick core 1, it is characterized in that serving as a contrast 2 outsides at iron sheet is provided with second layer iron sheet lining 5, is that 5 of outer iron sheet linings are cast with refractory materials 6 at iron sheet lining 2 and the second layer.
The outer iron sheet lining 5 of the utility model and refractory materials 6 form protective; reach the purpose of double-layer seal; the one, the iron sheet that the molten steel at cracking place can not directly penetrate into gas permeable brick core 1 on the protection ectosome brick cup 3 serves as a contrast 2 places; the 2nd, when the improper ventilative point of outer iron sheet lining 5 appearance is ventilative; iron sheet lining 2 by internal layer forms the double shielding layer, guarantees that gas can normally enter in the ladle, can guarantee the rate of blowing out of refining; it is ladle-to-ladle to reduce ladle molten steel, and the product degradation that does not become to cause uses with blowing.

Embodiment
The utility model refining ladle gas permeable brick is made of gas permeable brick core 1, iron sheet lining 2, ectosome brick cup 3, ventpipe 4, offer ventilating slit 10 at gas permeable brick core 1, it is characterized in that serving as a contrast 2 outsides at iron sheet is provided with second layer iron sheet lining 5, is cast with refractory materials 6 at iron sheet lining 2 and 5 of second layer iron sheet linings.
Claims (1)
1. refining ladle double-layer air-permeable brick, comprise gas permeable brick core (1), iron sheet lining (2), ectosome brick cup (3), ventpipe (4), offer ventilating slit (10) at gas permeable brick core (1), it is characterized in that being provided with second layer iron sheet lining (5) in iron sheet lining (2) outside, is to be cast with refractory materials (6) between outer iron sheet lining (5) at iron sheet lining (2) and the second layer.
