Abstract
The utility model discloses a built-in air-permeable brick formed by blowing argon at the bottom of a steel ladle, which comprises a brick cup sleeve and an air-permeable brick core, wherein the brick cup sleeve and the air-permeable brick core are independently formed, the air-permeable brick core is assembled in the brick cup sleeve, the air-permeable brick core and the brick cup sleeve are combined through refractory mortar material, and the surface of the brick cup sleeve, which is combined with the air-permeable brick core, is a curved surface. The brick cup sleeve and the air-permeable brick core are combined through the refractory mortar material, thereby avoiding the high-temperature cracking situation caused by different expansion coefficients of an iron piece and the refractory material, greatly improving the finished product rate of production of the built-in air-permeable bricks, and simultaneously prolonging the service life. In addition, the curved surface is formed in the brick cup sleeve, and the bottom of the air-permeable brick core is sealed with self-flow castable, thereby preventing high-temperature molten steel from infiltrating between a brick cup and the air-permeable brick and upgrading the using safety.
Description
Technical field
The utility model relates to a kind of steel ladle bottom argon blowing built-in type air brick.
Background technology
The built-in type air brick adopts the mode moulding of global formation at present, and promptly the air brick core directly is assembled into global formation in the brick cup mould.Because the brick cup cover is refractory material, and air brick core outer wrapping is iron sheet (or stainless steel sheet|), different owing to two kinds of material coefficients of expansion in high-temperature baking or use, often because air brick core parcel expands bigger with iron sheet, cause brick cup cover serious cracking, finally make the brick body scrap or use in brick cup cover cracking, molten steel infiltrates by the crack and causes security incident.In addition, existing brick cup cover is that straight line combines with air brick core faying face, and is inconsistent owing to the coefficient of expansion between air brick core and the brick cup cover in the high temperature use, forms the gap easily, and high-temperature molten steel infiltrates by the gap, causes security incident.
Summary of the invention
In order to address the above problem, the utility model provides a kind of steel ladle bottom argon blowing built-in type air brick, and effectively solving in the baking of built-in type air brick or the use easily, cracking and built-in type air brick brick cup cover combine the problem of oozing steel easily with air brick core straight line.
To achieve these goals, the technical solution adopted in the utility model is: a kind of steel ladle bottom argon blowing built-in type air brick, comprise brick cup cover and air brick core, described brick cup cover and the independent moulding of air brick core, described air brick core is assembled in the brick cup cover, and combine by refractory clay between air brick core and the brick cup cover, the brick cup cover is a curved surface with air brick core faying face.
Advantage of the present utility model is: the brick cup cover combines by refractory clay with the air brick core, avoided because of ironware and the different high temperature cracking situation that causes of the refractory material coefficient of expansion, the rate of manufacturing a finished product of built-in type air brick increases substantially, and also is improved service life simultaneously.In addition, form curved surface in the brick cup cover, and seal with gravity flow pouring material bottom the air brick core, avoided high-temperature molten steel to infiltrate between brick cup and air brick, safety in utilization gets a promotion.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Referring to Fig. 1, a kind of steel ladle bottom argon blowing built-in type air brick, comprise brick cup cover 1 and air brick core 2, described brick cup cover 1 and the 2 independent moulding of air brick core, described air brick core 2 is assembled in the brick cup cover 1, and combine by refractory clay between air brick core 2 and the brick cup cover 1, brick cup cover 1 is a curved surface with air brick core 2 faying faces.
The utility model when brick cup overlaps the assembling of 1 production mould, overlaps the rubber ring of 1 core rod apart from the about 20mm of diameter of scope cover of major part direction 30～50mm at brick cup in use, and assembling is produced in the usual way then; When brick cup overlaps the 1 maintenance demoulding rubber ring is taken out, just formed the groove of the about 20mm of a loop diameter in the brick cup cover 1, brick cup cover 1 baking in the usual way after the demoulding; During the assembling of brick cup cover 1 and air brick core 2, after being cooled to below 50 ℃, can assemble by brick cup cover 1 after the baking with air brick core 2, deployed refractory clay is spread upon air brick core 2 drum surfaces equably, its THICKNESS CONTROL is between 1～2 mm, then air brick core 2 is vertically put into brick cup cover 1, both hands knock the air chamber base plate with wooden mallet at last and overlap 1 upper surface level up to silk seat upper end with brick cup firmly toward pressing down; After 2 extruding of air brick core put in place, remove the seam pug 3 in air brick core 2 big or small two ends and the locating slot, and beat whole clean; The gravity flow pouring material 4 that mixes is poured in the locating slot.
Claims (1)
1. steel ladle bottom argon blowing built-in type air brick, comprise brick cup cover and air brick core, it is characterized in that: described brick cup cover and the independent moulding of air brick core, described air brick core is assembled in the brick cup cover, and combine by refractory clay between air brick core and the brick cup cover, the brick cup cover is a curved surface with air brick core faying face.
