Abstract
A kind of penetration preventing steel ladle air brick, its be mainly technically characterized by by durability preferably, finer and close seam self-flowing material it is all or part of substitution porous core body refractory material and metal shell between seam chamotte, during air brick use, particularly air brick uses the later stage, the situation that steel is oozed by chamotte position for preventing air brick from relatively frequently occurring is played, there is safety, easily make, stable structure.
Description
Technical field
Refractory for Ladle field is the utility model is related to, particularly a kind of antiseepage in external refining bottom blowing ar system
Steel air brick of steel ladle.
Background technology
Refinement outside-furnace technique can complete the smelting of many steel items physicochemical properties, its key position is BOTTOM ARGON BLOWING system
System, core element is BOTTOM ARGON BLOWING air brick.
Steel ladle bottom argon blowing air brick is generally made of ventilating seat brick and porous core two parts, used in steel industry at present
Air brick is divided into two kinds of monolithic devices and fitted outside by composition form, and the meaning of ventilating seat brick is to be effectively protected porous core, and
Porous core is then the medium element that argon gas is provided into ladle.
Porous core is made of body refractory material, metal shell, seam chamotte, rear cover and several parts of tail pipe, main to make
Technique is to make body refractory material using the method for moulding by casting, pass through seam after drying, 800 DEG C -1700 DEG C are burnt till
Chamotte is assembled in metal shell, then welds rear cover and tail pipe is completed to make.If monolithic devices air brick, it is also necessary to will be saturating
Gaseous core is prefabricated inside brick cup or to be assembled in inside brick cup.
Seam chamotte is made of various refractory powders and chemical bond needed for porous core manufacturing process, in fluid
Shape, contained humidity is more, therefore the performance such as the consistency of seam chamotte, intensity is poor compared with castable, in body fire proofed wood
In material and metal shell assembling process, it is easy to larger bubble occur, or even length occur up to the other void defects of Centimeter Level.
Air brick faces larger temperature gradient in use, by oxygen corrode and mechanical erosion when oxygen rifle cleans,
Air brick uses the later stage, and porous core shortens, and at this time, under the working condition that porous core is faced, seam chamotte is if there is some
The defects of bubble, gap, during when oxygen rifle cleans, molten steel is easy to along gap into air inlet chamber, ooze after melting rear cover and tail pipe
Go out, it is also higher in steel industry site of deployment, the probability for this accident occur.
The content of the invention
To solve the problems, such as in steel industry that air brick uses to the later stage and occurs oozing steel, this practicality because of seam chamotte position
Technical solution is used by new：
1, at least in porous core bottom, the structure of porous core by body refractory material, seam self-flowing material, cone-shaped metal outside
Shell, rear cover and several parts of tail pipe are formed.
2, the thickness of seam self-flowing material is 5mm-20mm.
3, chamotte of the seam self-flowing material substitution porous core bottom at least in 50mm altitude ranges.
4, seam gravity flow pouring material can be all arranged to around porous core body refractory material.
5, the optimal selection of seam self-flowing material material is the self-flowing material with porous core body refractory material same material.
The beneficial effects of the utility model are：
1, intensity and the higher seam self-flowing material of consistency instead of traditional seam chamotte, effectively prevent molten steel to ooze
The possibility gone out, seam self-flowing material are approached with body refractory material material, and structure is stablized relatively in application process.
2, traditional seam chamotte contains substantial amounts of chemical bond, some influences, but seam can be caused on production environment
The above problem is then not present in self-flowing material.
3, the utility model implements simple, easy system.

Embodiment
1, according to designing porous core body refractory material 1. shape specification Fig. 2 or 3 Suo Shi.
2, porous core body refractory material is made 1., by taking corundum spinelle as an example：
2.1 by specification for the plate diamond spar 30% of 3-6mm, the plate diamond spar 24% of 1-3mm, 0-1mm plate diamond spar
16%th, 70 pure calcium aluminate cements 5%, alumina powder 5%, spinel powder 20%, additional water-reducing agent FS10 are 0.15% mixing
The cleaning tap water for adding 4.0% stirs evenly rear vibration moulding.
2.2 conserve 12h under the conditions of 30-60 DEG C.
It is dry under the conditions of 250 DEG C of highest after 2.3 form removals tool.
2.4 burn till adobe at 1600 DEG C of highest.
2.5 make when region of interest set secure ID 4., gas chamber 5..
3, according to the topology example of Fig. 2：
1. 3. 2. adobe after burning till i.e. body refractory material is assembled in one by 3.1 with metal shell by seam chamotte
Rise, ensure that 2. thickness is 1-1.5mm to seam chamotte.
3.2 remove perfusion seam self-flowing materials 8. site residues seam chamotte 2..
3.3 plate diamond spar 48% by specification for 1-3mm, the plate diamond spar 24% of 0-1mm, 70 pure calcium aluminate cements 6%,
Alumina powder 6%, spinel powder 16%, additional water-reducing agent FS10 are 0.15%, add 4.1% the mixing of cleaning tap water it is equal
Required position is poured in after even.
Natural curing is to curdled appearance 8. 3.4 seam self-flowing materials irrigate after.
It is dry under the conditions of up to 250 DEG C after 3.5 solidifications.
3.6 welding rear covers are 6. and tail pipe is completed porous core and made.
Porous core is fixed on ventilating seat brick by 3.7, and 7. moulding by casting ventilating seat brick is 7. in mould.
