Description

Technical Field

[0001] This utility model relates to the field of magnesia-carbon brick technology, specifically to an easy-to-assemble low-carbon magnesia-carbon brick. Background Technology

[0002] Low-carbon magnesia-carbon bricks are a type of improved magnesia-carbon refractory material. Their core characteristic is that the carbon content is significantly lower than that of traditional magnesia-carbon bricks. They are mainly used for the lining of converters, AC electric arc furnaces, DC electric arc furnaces, and slag lines in ladles.

[0003] Existing magnesia-carbon bricks all adopt a standard cuboid structure. The bricks are not easy to fit together when stacked, and they are prone to sliding against each other. Furthermore, the connection strength between adjacent magnesia-carbon bricks is poor, which makes assembly difficult and affects the performance of the furnace bottom and ladle.

[0004] Therefore, it is necessary to design an easy-to-assemble low-carbon magnesia-carbon brick to improve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs an easy-to-assemble low-carbon magnesia-carbon brick. This magnesia-carbon brick aims to solve the technical problems of existing magnesia-carbon bricks, such as difficulty in fitting the bricks together when stacked, poor connection strength, and reduced ease of assembly and efficiency of use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easily assembled low-carbon magnesia-carbon brick includes a magnesia-carbon brick body. A set of trapezoidal slots is provided on both sides of the magnesia-carbon brick body. A set of insertion holes is provided on one side of the magnesia-carbon brick body above and below the trapezoidal slots. A set of insertion rods is fixedly connected to the other side of the magnesia-carbon brick body at positions corresponding to the insertion holes. A pair of mating slots are provided on the top of the magnesia-carbon brick body. A mating strip is fixedly connected to the bottom of the magnesia-carbon brick body at positions corresponding to the mating slots. A wear-resistant shell is inserted into the front of the magnesia-carbon brick body.

[0008] Preferably, the inner wall of the insertion hole and the corners of the insertion rod are both designed with a rounded arc shape, and the insertion rod and the magnesium carbon brick body are an integral structure.

[0009] Preferably, the depth of the insertion hole is the same as the length of the insertion rod, and the two sets of magnesia-carbon bricks are connected by insertion holes and insertion rods.

[0010] By adopting the above technical solution, two adjacent sets of magnesia-carbon bricks are spliced ​​and assembled by inserting a rod into the insertion hole, which improves the connection strength and assembly convenience between the two sets of magnesia-carbon bricks.

[0011] Preferably, both the docking slot and the docking strip have a T-shaped cross-sectional design, and the docking strip and the magnesia-carbon brick body are an integral structure.

[0012] Preferably, the depth of the mating slot is the same as the length of the mating strip, and the two sets of magnesia-carbon bricks in the longitudinal direction are connected by the mating slot and the mating strip.

[0013] By adopting the above technical solution, two longitudinally adjacent groups of magnesia-carbon bricks are spliced ​​and assembled by inserting butt strips into butt slots, thereby improving the connection strength and assembly convenience between the two longitudinal groups of magnesia-carbon bricks.

[0014] Preferably, the wear-resistant shell has a U-shaped cross-section design, and a set of trapezoidal inserts are fixedly connected to both sides of the inner wall of the wear-resistant shell at positions corresponding to the trapezoidal slots. The wear-resistant shell is connected to the trapezoidal slots by inserting the trapezoidal inserts.

[0015] By adopting the above technical solution, the wear-resistant shell is inserted into the trapezoidal slots on both sides of the magnesia-carbon brick body through trapezoidal inserts, so that the wear-resistant shell wraps around the outside of the magnesia-carbon brick body, improving the wear resistance of the magnesia-carbon brick body, and facilitating the replacement of the wear-resistant shell in the later stage.

[0016] Preferably, a through hole is provided on one side of the wear-resistant shell at a position corresponding to the insertion hole, and the internal contour size of the through hole corresponds to the insertion hole. A clearance groove is provided on the other side of the wear-resistant shell at a position corresponding to the insertion rod.

[0017] By adopting the above technical solution, when splicing and assembling two sets of magnesia-carbon bricks in the horizontal direction, the insert rod passes through the through hole and is inserted into the insertion hole to improve the stability of the wear-resistant shell installed on the outside of the magnesia-carbon brick after the magnesia-carbon brick is assembled, and prevent the wear-resistant shell from loosening and falling off. When the wear-resistant shell is installed on the outside of the magnesia-carbon brick, the insert rod is avoided by the avoidance groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The two groups of magnesia-carbon bricks in the horizontal direction are connected by inserting holes and inserting rods, and the two groups of magnesia-carbon bricks in the vertical direction are connected by inserting slots and inserting strips, which improves the connection strength and assembly convenience between the magnesia-carbon bricks.

[0020] 2. The wear-resistant shell is connected to the trapezoidal slot by a trapezoidal insert block, so that it wraps around the outside of the magnesia-carbon brick body, improving the wear resistance of the magnesia-carbon brick body and facilitating the replacement of the wear-resistant shell later. The two sets of magnesia-carbon brick bodies in the horizontal direction are connected by insert rods passing through the through holes and inserting into the holes, which improves the stability of the wear-resistant shell installed on the outside of the magnesia-carbon brick body after the magnesia-carbon brick bodies are assembled, and prevents the wear-resistant shell from loosening and falling off.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] This utility model provides an easy-to-assemble low-carbon magnesia-carbon brick, which aims to solve the technical problems of existing magnesia-carbon bricks, such as difficulty in fitting the bricks together when stacked, poor connection strength, and impact on assembly convenience and usage efficiency.

[0030] Please see Figures 1-5 This embodiment provides an easy-to-assemble low-carbon magnesia-carbon brick, including a magnesia-carbon brick body 1. A set of trapezoidal slots 101 are provided on both sides of the magnesia-carbon brick body 1. A set of insertion holes 102 are provided on one side of the magnesia-carbon brick body 1 above and below the trapezoidal slots 101. A set of insertion rods 103 are fixedly connected to the other side of the magnesia-carbon brick body 1 at the position corresponding to the insertion holes 102. The inner walls of the insertion holes 102 and the corners of the insertion rods 103 are all designed with a rounded cross-sectional shape. The insertion rods 103 and the magnesia-carbon brick body 1 are an integral structure. The depth of the insertion holes 102 is the same as the length of the insertion rods 103. The two sets of magnesia-carbon brick bodies 1 in the horizontal direction are connected by insertion holes 102 and insertion rods 103, which improves the connection strength and assembly convenience between the two sets of magnesia-carbon brick bodies 1 in the horizontal direction.

[0031] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The top of the magnesia-carbon brick body 1 is provided with a pair of mating slots 104. The bottom of the magnesia-carbon brick body 1 and the position corresponding to the mating slots 104 are fixedly connected with mating strips 105. The cross-sectional shape of the mating slots 104 and the mating strips 105 are both T-shaped structures. The mating strips 105 and the magnesia-carbon brick body 1 are integral structures. The depth of the mating slots 104 is the same as the length of the mating strips 105. The two sets of magnesia-carbon brick bodies 1 in the longitudinal direction are connected by mating slots 104 and mating strips 105, which improves the connection strength and assembly convenience between the two sets of magnesia-carbon brick bodies 1 in the longitudinal direction.

[0032] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 A wear-resistant shell 2 is inserted into the front of the magnesia-carbon brick body 1. The wear-resistant shell 2 has a U-shaped cross-section. A set of trapezoidal inserts 201 are fixedly connected to both sides of the inner wall of the wear-resistant shell 2 at positions corresponding to the trapezoidal slots 101. The wear-resistant shell 2 is connected to the trapezoidal slots 101 through the trapezoidal inserts 201, so that it wraps around the outside of the magnesia-carbon brick body 1, improving the wear resistance of the magnesia-carbon brick body 1 and facilitating the replacement of the wear-resistant shell 2 later. A through hole is opened on one side of the wear-resistant shell 2 at a position corresponding to the insertion hole 102. 202. The internal contour size of the through hole 202 corresponds to that of the insertion hole 102. The two sets of magnesia-carbon brick bodies 1 are connected by inserting rods 103 through the through hole 202 and inserting them into the insertion hole 102. This improves the stability of the wear-resistant shell 2 after the magnesia-carbon brick bodies 1 are assembled and installed on the outside of the magnesia-carbon brick bodies 1, and prevents the wear-resistant shell 2 from loosening and falling off. On the other side of the wear-resistant shell 2, at a position corresponding to the inserting rod 103, a clearance groove 203 is provided. When the wear-resistant shell 2 is installed on the outside of the magnesia-carbon brick body 1, the clearance groove 203 avoids the inserting rod 103.

[0033] In addition, it should be noted that both the magnesia-carbon brick body 1 and the wear-resistant shell 2 are existing technologies, and their internal working principles and operating procedures will not be described in detail here.

[0034] The working process of this utility model is as follows: First, the wear-resistant shell 2 is connected to the trapezoidal slot 101 through the trapezoidal insert 201. When the wear-resistant shell 2 is installed on the outside of the magnesia-carbon brick body 1, the insert rod 103 is avoided by the avoidance groove 203, so that the wear-resistant shell 2 wraps around the outside of the magnesia-carbon brick body 1, thereby improving the wear resistance of the magnesia-carbon brick body 1. The two sets of magnesia-carbon brick bodies 1 in the horizontal direction are connected to the insert rod 103 through the insertion hole 102. The two sets of magnesia-carbon brick bodies 1 in the vertical direction are connected to the butt joint slot 104 and the butt joint strip 105 through the butt joint slot 104, thereby improving the connection strength and assembly convenience between the two sets of magnesia-carbon brick bodies 1 in the adjacent direction. While the two sets of magnesia-carbon brick bodies 1 in the horizontal direction are being assembled, the magnesia-carbon brick bodies 1 are connected to each other through the insertion rod 103 passing through the through hole 202 and inserting it into the insertion hole 102, thereby improving the stability of the wear-resistant shell 2 installed on the outside of the magnesia-carbon brick body 1 after assembly, and preventing the wear-resistant shell 2 from loosening and falling off.

[0035] The entire operation process is simple and convenient. Compared with existing magnesia-carbon bricks, this utility model improves the ease of splicing and assembling of magnesia-carbon bricks and the connection strength, enhances the wear resistance of magnesia-carbon bricks, and improves the overall practicality.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
