Description

Technical Field

[0001] This utility model relates to the field of refractory brick material production, specifically a tooling for producing bottom-blown argon-permeable refractory bricks. Background Technology

[0002] Bottom-blown argon permeable bricks are key functional components used in steel ladle refining in iron and steel metallurgy. They are primarily used to agitate molten steel by blowing inert gas (such as argon) from the bottom, thereby homogenizing composition and temperature and removing inclusions. (See attached instruction manual.) Figure 1 As shown, the brick structure of a bottom-blown argon permeable brick generally includes an inner permeable brick core and an outer shell. The permeable brick core is vented through air channels, and the permeable brick core and the outer shell are often connected by an intermediate adhesive layer. In the existing technology, the installation of the permeable brick core and the outer shell involves placing the inner permeable brick core inside the outer shell and manually clamping it to lift it a certain distance, creating a cavity between the shell and the permeable brick core. Refractory mortar is injected into the cavity, and then the connection between the two is strengthened by manual pressing, thus forming the intermediate adhesive layer. This installation method requires multiple people to work together and consumes a lot of manpower; pressing the permeable brick core requires continuous work by a dedicated person, which is inefficient; and due to differences in pressing pressure and the lifting distance of the permeable brick core, there are large errors between the products. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tooling for producing bottom-blown argon permeable bricks. This tooling can replace manual labor and improve labor efficiency, and through standardized manufacturing, it can effectively improve the stability of product quality.

[0004] To address the existing technical problems, this utility model discloses a tooling for producing bottom-blown argon-permeable refractory bricks, including an outer fixed barrel and an inner fixed ring. The outer fixed barrel and the inner fixed ring are concentrically arranged. A fixing groove is provided on the top of the outer fixed barrel wall, and a vertically upward connecting rod is inserted and fixed in the fixing groove. The vertical connecting rod is connected to a horizontal connecting rod in the direction of the center of the outer fixed barrel. The inner fixed ring is fixed by the horizontal connecting rod.

[0005] A fixing cover is provided directly above the inner fixing ring, and upper fixing blocks are provided on both sides of the fixing cover. Lower fixing blocks are provided on both sides of the outer fixing barrel wall. The upper and lower fixing blocks are positioned correspondingly, and fasteners are provided between the upper and lower fixing blocks.

[0006] Preferably, the inner fixing ring is positioned at a higher height than the top of the outer fixing barrel.

[0007] Preferably, the diameter of the inner fixing ring is smaller than the diameter of the outer fixing barrel.

[0008] Preferably, the diameter of the fixing cover is larger than the diameter of the inner fixing ring.

[0009] Preferably, the fastener includes a fastening bolt and a fastening nut, and threaded holes are pre-drilled on both the upper and lower fixing blocks. The fastening bolt passes through the threaded holes of the upper and lower fixing blocks and is fixed to the upper and lower fixing blocks respectively by the fastening nut.

[0010] Preferably, the fastener is a fixing clip, which clamps the upper fixing block and the lower fixing block.

[0011] Preferably, the inner fixing ring is a hollow annular structure, and the inner fixing ring is integrated with the vertical connecting rod and the horizontal connecting rod.

[0012] The method of using this utility model is as follows: First, remove the inner fixing ring and the vertical connecting rod and horizontal connecting rod connected to it. Then, place the shell of the bottom-blown argon permeable brick into the outer fixing barrel. Next, insert the vertical connecting rod connected to the inner fixing ring into the fixing groove on the wall of the outer fixing barrel, so that the inner fixing ring is fixedly suspended directly above the outer fixing barrel. Then, place the permeable brick core of the bottom-blown argon permeable brick into the inner fixing ring. Since the permeable brick core has not yet been shaped, when it is placed into the inner fixing ring, the position of the permeable brick core is higher than the inner fixing ring. Finally, tighten the fasteners on the upper fixing block and the lower fixing buckle, so that the permeable brick core and the shell are tightly pressed together, improving the connection strength.

[0013] The beneficial effects of this utility model are: the preparation of special tooling and standardized operation can effectively improve the uniformity of product quality, and free up a large amount of manual labor, thereby improving production efficiency. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] like Figure 1 As shown, the brick structure of the bottom-blown argon permeable brick includes an inner permeable brick core 1 and an outer shell 2. The permeable brick core 1 is ventilated through the air channel 3, and the permeable brick core 1 and the outer shell 2 are often connected by an intermediate adhesive layer 4.

[0023] like Figure 2-4 As shown, a tooling for producing bottom-blown argon-permeable refractory bricks includes an outer fixed barrel 5 and an inner fixed ring 6, which are concentrically arranged. The top of the outer fixed barrel 5 is provided with a fixing groove 7, and a vertically upward vertical connecting rod 8 is inserted and fixed in the fixing groove 7. The vertical connecting rod 8 is connected to a horizontal connecting rod 9 pointing towards the center of the outer fixed barrel 5, and the inner fixed ring 6 is fixed by the horizontal connecting rod 9.

[0024] The inner fixing ring 6 is positioned higher than the top of the outer fixing barrel 5. The diameter of the inner fixing ring 6 is smaller than the diameter of the outer fixing barrel 5. The inner fixing ring 6 is a hollow ring structure and is an integral structure with the vertical connecting rod 8 and the horizontal connecting rod 9.

[0025] This design allows the inner fixing ring 6 to be suspended directly above the outer fixing barrel 5. The outer fixing barrel 5 contains the shell 2 of the bottom-blown argon permeable brick, while the permeable brick core 1, which contains the bottom-blown argon permeable brick, is placed inside the inner fixing ring 6. Since the bottom-blown argon permeable brick needs to be shaped after assembly, its current size is higher than the inner fixing ring 6. When the permeable brick core 1 is placed inside the inner fixing ring 6, it will be stuck, forming a cavity 10 between the permeable brick core 1 and the shell 2. After filling this cavity 10 with refractory mortar, an adhesive layer 4 of the bottom-blown argon permeable brick will be formed. Because the inner fixing ring 6 and the outer fixing barrel 5 are connected only by vertical connecting rods 8 and horizontal connecting rods 9 on both sides, there is a large gap between the inner fixing ring 6 and the outer fixing barrel 5, allowing for the pouring of refractory mortar. The concentric arrangement of the outer fixing barrel 5 and the inner fixing ring 6 ensures the alignment between the brick shell 2 and the permeable brick core 1, effectively guaranteeing the quality of the brick.

[0026] A fixing cover 11 is provided directly above the inner fixing ring 6. Upper fixing blocks 12 are provided on both sides of the fixing cover 11. Lower fixing blocks 13 are provided on both sides of the outer fixing barrel 5. The upper fixing blocks 12 and the lower fixing blocks 13 are positioned correspondingly. Fasteners 14 are provided between the upper fixing blocks 12 and the lower fixing blocks 13.

[0027] Because the breathable brick core 1 and the shell 2 need to be tightly connected to improve the integrity and connection strength of the brick body, fasteners 14 are used to connect the fixing cover 11 and the outer fixing barrel 5 together. Applying a downward force to the fixing cover 11 compresses the breathable brick core 1 located between the inner fixing ring 6 and the fixing cover 11, causing it to move downwards. Thus, the breathable brick core 1 and the shell 2 are tightly connected together. To improve the compression effect, the diameter of the fixing cover 11 is set to be larger than the diameter of the inner fixing ring 6.

[0028] Regarding the selection of fastener 14, in Embodiment 1: Fastener 14 includes a fastening bolt and a fastening nut. Threaded holes are pre-drilled on both the upper fixing block 12 and the lower fixing block 13. The fastening bolt passes through the threaded holes in the upper fixing block 12 and the lower fixing block 13, and is fixed to the upper fixing block 12 and the lower fixing block 13 respectively by the fastening nut. During use, the distance between the fixing cover 11 and the lower fixing bucket can also be adjusted by tightening the fastening nut, thereby adjusting the distance between the breathable brick core 1 and the shell 2.

[0029] Obviously, fastener 14 can also be like... Figure 5 The second embodiment shown: The fastener 14 is a fixing clip, such as a C-clamp, which clamps the upper fixing block 12 and the lower fixing block 13.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
