[0006] Preferably, the brick body, the second positioning block and the positioning groove are all designed in a fan-shaped structure, and the first positioning block is designed in a fan-shaped frame structure.

[0007] Preferably, first chamfers are opened at the top edge of the first positioning block, and second chamfers are opened in the positioning groove corresponding to the first positioning block.

[0009] Preferably, the first positioning block and the positioning groove are arranged correspondingly, and the first positioning block and the second positioning block are arranged correspondingly.

[0010] Compared with the prior art, the beneficial effect of the utility model is that through the structural design of the first positioning block, the second positioning block and the positioning groove, the first positioning block, the positioning groove and the second positioning block are fitted in a square structure, so that the fitting between the brick bodies is closer. At the same time, the fan-shaped structure design of the first positioning block, the positioning groove and the second positioning block can make the force of the brick body stacking more uniform and the fitting more stable, effectively improving the stacking strength and stability of the magnesia-carbon brick.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5 , the present utility model provides a technical solution: a magnesia-carbon brick block that can be stably stacked, including a brick body 1, a first positioning block 2 is fixedly connected to the top end of the brick body 1, a plurality of glue overflow grooves 3 are arrayed and opened on the inner wall of the first positioning block 2, a positioning groove 4 is opened at the bottom end of the brick body 1, a second positioning block 5 is fixedly connected to the bottom end of the positioning groove 4, a high-temperature resistant coating 6 is provided on one side of the brick body 1, and an oxidation coating 7 is provided on one side of the high-temperature resistant coating 6.

[0019] The brick body 1, the second positioning block 5 and the positioning groove 4 are all designed with a fan-shaped structure. The first positioning block 2 is designed with a fan-shaped frame structure and is applicable to the ladle. At the same time, the first positioning block 2, the second positioning block 5 and the positioning groove 4 with a fan-shaped structure are more adapted to the brick body, making the force distribution more uniform when the brick bodies 1 are stacked, and the fitting more stable. First chamfers 8 are provided at the top edges of the first positioning block 2, and second chamfers 9 corresponding to the first positioning block 2 are provided in the positioning groove 4, so that the outer side of the first positioning block 2 fits more closely with the positioning groove 4. Reinforcing ribs 10 are fixedly connected to the positioning groove 4 corresponding to the second positioning block 5, and the reinforcing ribs 10 are fixedly connected to the second positioning block 5, which is convenient for further strengthening the second positioning block 5 and at the same time making the inner side of the first positioning block 2 fit more closely with the positioning groove 4. The first positioning block 2 and the positioning groove 4 are arranged correspondingly, and the first positioning block 2 and the second positioning block 5 are arranged correspondingly, which is convenient for the first positioning block 2, the positioning groove 4 and the second positioning block 5 to be fitted in a zigzag structure, making the fitting between the brick bodies 1 more tight.

[0020] Specifically, when using the present utility model, the adhesive is applied to the center position of the top of the brick body 1 corresponding to the first positioning block 2. After aligning the positioning groove 4 and the second positioning block 5 at the bottom of the brick body 1 to be stacked with the first positioning block 2 of the bottom brick body 1 and inserting them, the excess adhesive under extrusion flows into the glue overflow groove 3 along the gap. At the same time, the high-temperature resistant coating 6 and the oxidation coating 7 can endow the brick body 1 with good high-temperature resistance and anti-oxidation performance.
