In a high-temperature environment, the brick body 1 will deform due to thermal expansion. The design of the deformation compensation groove 101 cleverly provides additional space to accommodate this expansion, effectively preventing cracking or falling off caused by limited expansion, which not only extends the service life of the magnesia-carbon brick, but also improves its stability and safety in a high-temperature environment; a plurality of expansion joints 103, formed at the bottom of the brick body 1, distributed in a linear array, used to provide the brick body 1 with free expansion space at high temperatures, and the careful arrangement of the expansion joints 103 makes The brick body 1 can expand freely at high temperature without stress concentration due to constraint, which helps to reduce the damage of thermal stress to the brick body 1 and improve the heat shock resistance and overall stability of the brick body 1; the reinforcing rib 2 is arranged in the brick body 1. The setting of the reinforcing rib 2 significantly enhances the mechanical strength and structural stability of the brick body 1. It can not only withstand stress from all directions, but also effectively disperse stress to prevent the brick body 1 from breaking due to uneven force. The presence of the reinforcing rib 2 greatly improves the service life of the magnesia carbon brick under high temperature and heavy load conditions; two support rods 3 are respectively connected to the two ends of the reinforcing rib 2 and are arranged on both sides of the brick body 1. The support rod 3 is used to increase the supporting force of the brick body 1. The ingenious combination of the support rod 3 and the reinforcing rib 2 enhances the supporting force and stability of the brick body 1. They can effectively resist external pressure and prevent the brick body 1 from deformation. The design of the support rod 3 enables the magnesia carbon brick to maintain excellent performance under harsh working conditions.
[0026] The brick body 1 includes: a butt joint 102, which is arranged along the width direction of the brick body 1 and is used to leave space between bricks to accommodate thermal expansion under high temperature. The butt joint 102 not only facilitates the installation and replacement of the brick body 1, but also reduces the extrusion and friction between the brick bodies 1 caused by thermal expansion, thereby extending the service life of the magnesia carbon brick; two grooves 104 are respectively opened on both sides of the brick body 1, and the two support rods 3 are respectively connected to the two grooves 104. The design of the grooves 104 provides a stable connection point for the support rods 3, so that the support rods 3 can be firmly connected to the brick body 1, thereby enhancing the overall stability of the brick body 1 and improving the supporting effect of the support rods 3; a through hole 105 runs through the brick body 1, and its two ends are respectively connected to the two grooves 104. The reinforcing rib 2 is arranged in the through hole 105. The design of the through hole 105 not only facilitates the installation and fixation of the reinforcing rib 2, but also allows heat to be freely transferred and dissipated in the brick body 1, thereby helping to reduce the internal temperature of the brick body 1, reduce the damage to the brick body 1 caused by thermal stress, and improve the heat resistance and service life of the magnesia carbon brick.
[0027] The reinforcement ribs 2 include several support rods 201 mounted on the reinforcement ribs 2 and connected to the brick body 1. The support rods 201 are arranged perpendicular to the reinforcement ribs 2 to disperse and withstand stress from all directions. This perpendicular arrangement of the support rods 201 and the reinforcement ribs 2 forms a stable support network, enabling the brick body 1 to withstand stress from all directions. The presence of the support rods 201 effectively disperses stress and prevents the brick body 1 from cracking due to uneven stress. This improves the mechanical strength and structural stability of the magnesia-carbon brick.
[0028] The cross-section of the deformation compensation groove 101 is arc-shaped, which is used to evenly disperse stress when subjected to thermal expansion, reducing damage to the brick body 1 caused by stress concentration, helping to extend the service life of the magnesia carbon brick and improve its stability and safety in high temperature environments.
[0029] During use, a deformation compensation groove 101 is formed on the top of the brick body 1 to provide additional space to accommodate thermal expansion under high temperature, and a number of expansion joints 103 distributed in a linear array are formed at the bottom of the brick body 1 to allow the brick body 1 to expand freely under high temperature. A reinforcing rib 2 is provided in the brick body 1 to enhance the mechanical strength and structural stability of the brick body 1. Two support rods 3 are respectively connected to the two ends of the reinforcing rib 2 and are provided on both sides of the brick body 1 to increase the supporting force of the brick body 1. A butt joint 102 is provided along the width direction of the brick body 1 to leave space between bricks to accommodate thermal expansion under high temperature. Grooves 104 are respectively provided on both sides of the brick body 1 to firmly connect the support rods 3, and a through hole 105 is provided through the brick body 1, both ends of which are connected to the groove 104 to facilitate the installation and fixation of the reinforcing rib 2 and promote the free transfer and dissipation of heat. The reinforcing rib 2 is installed in the through hole 105 to ensure that the reinforcing rib 2 is firmly fixed It is fixed in the brick body 1, and several support rods 201 are installed on the reinforcement ribs 2, and the support rods 201 are arranged perpendicular to the reinforcement ribs 2 to form a stable support network. When the magnesia carbon brick is in a high temperature environment, the brick body 1 will be deformed due to thermal expansion. The design of the deformation compensation groove 101 and the expansion joint 103 allows the brick body 1 to expand freely at high temperatures to prevent cracking or falling off due to limited expansion. The support network formed by the reinforcement ribs 2 and the support rods 201 effectively disperses and withstands stress from all directions to prevent the brick body 1 from breaking due to uneven force. The support rod 3 is firmly connected to the brick body 1 through the groove 104, which enhances the overall stability of the brick body 1 and effectively resists external pressure. The design of the through hole 105 allows heat to be freely transferred and dissipated in the brick body 1, which helps to reduce the internal temperature of the brick body 1. The effective dissipation of heat reduces the damage to the brick body 1 caused by thermal stress and improves the heat resistance and service life of the magnesia carbon brick.
[0030] In summary, compared with the existing technology, it has the following beneficial effects:
[0031] By designing a deformation compensation groove 101 on the top of the brick body 1 and setting a linear array of expansion joints 103 at the bottom of the brick body 1, sufficient additional space is provided for the thermal expansion of the magnesia carbon brick in a high temperature environment, effectively preventing the brick body 1 from being squeezed, cracked or falling off due to limited expansion, and significantly improving the stability and safety of the brick body 1.
[0032] The reinforcing ribs 2 arranged in the brick body 1 and the supporting rods 3 connected thereto together constitute a stable supporting structure, which not only enhances the mechanical strength and structural stability of the magnesia carbon brick, but also effectively disperses the stress from all directions, preventing the brick body 1 from breaking due to uneven force.
