Description

Casting mold for electric smelting AZS bubbling brick

Technical Field

The utility model relates to a technical field is made to glass kiln refractory material, specifically is a casting die utensil that is used for electric smelting AZS bubbling brick.

Background

With the continuous progress of glass furnaces, most glass furnaces adopt a bubbling technology in order to improve the melting efficiency of glass and enhance the melting uniformity of glass liquid. The bubbling technology brings substantial benefits to glass production enterprises, but puts higher requirements on the quality of the electric melting bricks. Especially, the bubbling brick at the bottom of the furnace tank adopts the bubbling technology to accelerate the flow of glass liquid, and the erosion of the electric melting brick is also intensified continuously. If the bubbling brick has quality problems, the material leakage at the bottom of the kiln and the service life of the kiln can be reduced. The bubbling brick material is generally AZS41# with high grade, and has higher requirement on the compactness of the brick material. In order to consider the safety of the kiln, part of glass kilns even do not adopt domestic AZS bubbling bricks, which indicates that the quality of the bubbling bricks of domestic fused cast refractory material production enterprises still needs to be improved.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a casting die utensil for electric smelting AZS bubbling brick, this mould can improve the density of bubbling brick, reduce appearance defect, improve the whole quality of bubbling brick.

The utility model provides a technical scheme that its technical problem adopted is:

a casting mould for an electric smelting AZS bubbling brick comprises a casting inner core, wherein the inner cavity of the casting inner core is matched with the shape of the bubbling brick, a cutting loosening belt is arranged at the top of the casting inner core, and a casting riser is arranged at the top of the cutting loosening belt; the hot working body of the bubbling brick corresponding to the inner cavity of the casting inner core faces downwards, and the cold working body faces upwards; the hot working body of the bubbling brick corresponding to the inner cavity of the casting inner core is in a trapezoid table shape;

the volume ratio of the casting riser to the casting inner core is 1.3:1, and the volume ratio of the cutting loose belt to the casting inner core is 1: 1.

The utility model has the advantages that the casting direction of the inner core is changed, the cold working body of the bubbling brick is cast towards the hot working body, the volume ratio of the casting riser, the inner core and the cut loose belt is limited, the density of the bubbling brick is improved, and the appearance defect is reduced; the obtained thermal working body of the bubbling brick is in a trapezoid table shape, and four edges are cut according to needs to obtain a rectangular block shape, so that four vertical edges of the thermal working body of the bubbling brick can be prevented from cracking, and the quality of the bubbling brick is improved.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic view of the initial bubble brick cast by the present invention;

fig. 3 is a schematic view of the bubble block of fig. 2 after cutting.

Detailed Description

With reference to fig. 1 and 2, the utility model provides a casting mold for an electric smelting AZS bubbling brick, which comprises a casting inner core 1, wherein the inner cavity of the casting inner core 1 is adapted to the shape of the bubbling brick, a cutting loosening belt 2 is arranged on the top of the casting inner core 1, and a casting riser 3 is arranged on the top of the cutting loosening belt 2; the hot working body 4a of the bubbling brick corresponding to the inner cavity of the casting inner core 1 faces downwards, and the cold working body 4b faces upwards; the bubbling brick hot working body 4a corresponding to the inner cavity of the casting inner core is in a trapezoid table shape; the volume ratio of the casting riser to the casting inner core is 1.3:1, and the volume ratio of the cutting loose belt to the casting inner core is 1: 1.

When in casting, injecting the molten AZS41# material liquid from a casting riser 3, wherein the casting temperature is 1820-1840 ℃, the casting speed is 25kg/s, and the casting is finished when the material liquid reaches the upper edge of the overflowing riser; after casting, the whole is stored in an insulation box for 15 days, then the product is taken out when the temperature is reduced to room temperature, a casting riser is cut off, and a loose belt part is cut off, so that the initial bubbling brick shown in figure 2 is obtained; referring to fig. 3, the four edges of the thermal operating body 4a of the bubbling brick are cut as needed to obtain a rectangular block-shaped thermal operating body of the bubbling brick, and finally the required bubbling brick is obtained.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the invention is not limited to the embodiments described herein, but is capable of other embodiments according to the invention, and may be used in various other applications, including, but not limited to, industrial. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments by the technical entity of the present invention all still belong to the protection scope of the technical solution of the present invention.
