Description

Technical Field

[0001] This utility model relates to the field of refractory bricks, specifically a composite steel ladle refractory brick. Background Technology

[0002] In the complex and critical industrial process of steel smelting, the steel ladle, as an important container, undertakes important tasks such as holding and transferring high-temperature molten steel and carrying out necessary refining processes. The refractory bricks of the steel ladle, as a key component of the ladle lining, directly affect the service life of the steel ladle, the quality of the molten steel, and the safety and economy of the entire steel smelting process.

[0003] Traditional steel ladle refractory bricks mostly adopt a simple solid structure. Therefore, under high-temperature environments, the thermal stress distribution inside the refractory bricks is uneven, which easily leads to cracks. These cracks gradually expand over time, eventually causing the refractory bricks to break and fail. Moreover, the single-pore structure cannot effectively disperse and transfer stress, making the refractory bricks prone to localized breakage when subjected to mechanical impact, affecting the overall service life of the steel ladle. Furthermore, under the action of high temperature and mechanical vibration, the mortar is prone to drying, cracking, and falling off, causing the connections between refractory bricks to loosen and reducing overall stability. This not only creates gaps in the steel ladle lining, increasing the risk of molten steel leakage, but also affects the thermal insulation performance of the steel ladle, leading to heat loss and increased energy consumption. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a composite steel ladle refractory brick to solve the technical problems of traditional steel ladle refractory bricks, which are prone to cracking and expansion due to uneven thermal stress distribution at high temperatures caused by simple solid structure, the inability of single-pore structure to effectively disperse and transfer stress leading to local breakage under mechanical impact, and the easy drying and falling off of slurry under high temperature and mechanical vibration, resulting in loosening of refractory brick connections, reduced overall stability, increased risk of molten steel leakage, and impact on thermal insulation performance and increased energy consumption.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite steel ladle refractory brick, comprising a refractory brick, wherein the refractory brick comprises an arc-shaped brick body, wherein the back of the arc-shaped brick body is provided with a plurality of equally spaced circular holes, and reinforcing ribs are provided in the plurality of circular holes, and the reinforcing ribs are arranged in a honeycomb structure.

[0006] The top of the arc-shaped brick body is provided with a reinforcing ring groove, and multiple refractory bricks are provided. The multiple refractory bricks are arranged in a ring array at equal intervals, and the multiple reinforcing ring grooves are connected in a circular structure.

[0007] By adopting the above technical solution, the back of the arc-shaped brick body is provided with multiple equidistant circular holes and honeycomb-shaped reinforcing ribs, and a reinforcing ring groove is opened at the top. Multiple refractory bricks are arranged in a ring to connect the reinforcing ring grooves. This design enhances the strength of the masonry, facilitates the assembly into a ring-shaped masonry, and improves the overall stability.

[0008] Furthermore, reinforcing rings are installed in the reinforcing ring grooves on the plurality of arc-shaped bricks, and the reinforcing rings are made of heat-resistant stainless steel.

[0009] By adopting the above technical solution, a heat-resistant stainless steel reinforcing ring is installed in the reinforcing ring groove of the arc-shaped brick body. The heat-resistant stainless steel has stable performance at high temperature and can tighten multiple refractory bricks, enhance the overall connection of the ring masonry, and prevent the refractory bricks from loosening.

[0010] Furthermore, one end of the arc-shaped brick is provided with an arc-shaped protrusion, and the other end of the arc-shaped brick is provided with an arc-shaped groove. Multiple refractory bricks are connected to the arc-shaped protrusions of adjacent refractory bricks through their arc-shaped grooves to form a ring-shaped masonry.

[0011] By adopting the above technical solution, an arc-shaped protrusion is provided at one end of the arc-shaped brick body, and an arc-shaped groove is provided at the other end. Multiple refractory bricks are joined together to form a ring-shaped masonry. This structure makes the refractory bricks tightly connected, facilitates assembly, and enables the rapid construction of a masonry structure that conforms to the shape of a steel ladle.

[0012] Furthermore, the cross-sections of the arc-shaped protrusion and the arc-shaped groove are adapted to each other in an arc-shaped structure, and the outer surface of the arc-shaped protrusion and the inner surface of the arc-shaped groove are closely fitted together.

[0013] By adopting the above technical solution, the arc-shaped protrusion and the arc-shaped groove cross section are adapted to each other and fit tightly. This structure further enhances the connection between refractory bricks, effectively prevents molten steel leakage, reduces heat loss, and improves the safety and heat preservation performance of the ladle.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] A composite steel ladle refractory brick, such as Figure 1-4 As shown, it includes a refractory brick 1, which includes an arc-shaped brick body 101. The back of the arc-shaped brick body 101 is provided with a plurality of equally spaced circular holes 104, and reinforcing ribs 105 are provided in the plurality of circular holes 104, and the reinforcing ribs 105 are arranged in a honeycomb structure.

[0030] The top of the arc-shaped brick body 101 has a reinforcing ring groove 106. Multiple refractory bricks 1 are arranged in a ring array at equal intervals. The multiple reinforcing ring grooves 106 are interconnected in a circular structure. Multiple equally spaced circular holes 104 are opened on the back of the arc-shaped brick body 101, and honeycomb-shaped reinforcing ribs 105 are installed within these holes. This design effectively disperses stress, enhances the strength of the brick body, and prevents cracking. Simultaneously, the reinforcing ring grooves 106 on the top of the arc-shaped brick body 101, when multiple refractory bricks 1 are arranged in a ring array at equal intervals, connect in a circular structure, providing a foundation for subsequent installation of reinforcing rings. This helps connect multiple refractory bricks into a whole, improving the overall stability of the ring masonry and meeting the requirements for ladle use.

[0031] See Figure 1 Reinforcing rings 2, made of heat-resistant stainless steel, are installed within the reinforcing ring grooves 106 on multiple arc-shaped bricks 101. Due to the excellent high-temperature stability and strength of heat-resistant stainless steel, the reinforcing rings 2 are not easily deformed under the high-temperature working environment of the ladle, and can continuously apply clamping force to the multiple refractory bricks 1. The reinforcing ring grooves 106 cooperate with the reinforcing rings 2, ensuring the reinforcing rings 2 are securely embedded, forming a reliable clamping constraint, effectively preventing the refractory bricks 1 from loosening under high temperature and mechanical vibration, enhancing the overall connection and stability of the annular masonry, and ensuring the normal operation of the ladle.

[0032] See Figure 3 , Figure 4One end of the arc-shaped brick body 101 is provided with an arc-shaped protrusion 102, and the other end is provided with an arc-shaped groove 103. Multiple refractory bricks 1 are connected to the arc-shaped protrusions 102 of adjacent refractory bricks through their arc-shaped grooves 103 to form an annular masonry. This design makes the connection between refractory bricks simpler and more precise. During assembly, only the protrusions and grooves of adjacent refractory bricks need to be aligned, which greatly improves assembly efficiency. At the same time, this structure can ensure the integrity and continuity of the annular masonry, so that the refractory bricks are tightly bonded to form an organic whole, which can better withstand various stresses in the ladle.

[0033] See Figure 1 , Figure 4 The cross-sections of the arc-shaped protrusion 102 and the arc-shaped groove 103 are adapted to each other in an arc-shaped structure, and the outer surface of the arc-shaped protrusion 102 is tightly fitted to the inner surface of the arc-shaped groove 103. This tight fit design effectively reduces the formation of gaps when connecting the refractory bricks 1. During the use of the ladle, it can prevent molten steel from leaking through the gaps between the refractory bricks, avoiding safety accidents. At the same time, the tight connection can reduce heat loss through the gaps, improve the heat preservation performance of the ladle, reduce energy consumption, extend the service life of the ladle, and improve the overall safety and economy of the ladle.

[0034] See Figure 1 The circular holes 104 are evenly distributed along the back of the arc-shaped brick body 101, and the reinforcing ribs 105 penetrate multiple circular holes 104 to form a continuous support structure. When the refractory brick is subjected to external force, the evenly distributed circular holes 104 and the continuous reinforcing ribs 105 can evenly distribute the stress throughout the entire brick body, avoiding stress concentration in a localized area. This structure enhances the overall strength and deformation resistance of the arc-shaped brick body 101, making the refractory brick less prone to damage under harsh environments such as high temperatures and mechanical impacts, improving the reliability and service life of the refractory brick, and reducing the cost of using the ladle.

[0035] See Figure 3 , Figure 4The cross-sectional shape of the reinforcing ring groove 106 is adapted to the outer contour of the reinforcing ring 2. The reinforcing ring 2 is embedded in the reinforcing ring groove 106 and forms a clamping constraint. This adapted design allows the reinforcing ring 2 to be securely installed in the reinforcing ring groove 106, preventing it from loosening due to vibration or temperature changes during the use of the ladle. The reinforcing ring 2 applies a uniform clamping force to multiple refractory bricks 1, tightly connecting the refractory bricks together to form a stable annular masonry structure. This effectively prevents the refractory bricks from shifting, enhances the overall structural strength of the ladle, and ensures the safe operation of the ladle under high temperature and high stress environments.

[0036] See Figure 1 , Figure 4 Refractory brick 1 is made of alumina-carbon or magnesia-carbon composite refractory material. Both alumina-carbon and magnesia-carbon composite refractory materials possess excellent high-temperature resistance, maintaining stable physical and chemical properties in the high-temperature environment of the ladle, and are not easily softened or deformed. Simultaneously, they also possess good corrosion resistance, effectively resisting the erosion of various chemicals in molten steel and reducing refractory brick wear. Refractory brick 1 made from these two materials can operate stably for a long time in the complex working environment of the ladle, reducing the frequency of refractory brick replacement, lowering the operating cost of the ladle, and improving the production efficiency of the ladle.

[0037] The implementation principle of this embodiment is as follows: First, in view of the structural strength problem of the refractory brick 1 itself, multiple equally spaced circular holes 104 are opened on the back of the arc-shaped brick body 101, and reinforcing ribs 105 with a honeycomb structure are set in the circular holes 104. Since the circular holes 104 are evenly distributed along the back of the arc-shaped brick body 101, the reinforcing ribs 105 penetrate multiple circular holes 104 to form a continuous support structure. When the refractory brick is in a high-temperature environment or is subjected to mechanical impact, the honeycomb structure of the reinforcing ribs 105 can effectively disperse and transfer stress, avoid stress concentration in a certain part, thereby enhancing the structural strength of the refractory brick 1 and preventing cracks caused by uneven thermal stress distribution and local breakage when subjected to mechanical impact.

[0038] Secondly, to address the overall stability issue of the annular masonry composed of multiple refractory bricks 1, a reinforcing ring groove 106 is formed at the top of the arc-shaped masonry 101. When multiple refractory bricks 1 are arranged in an equidistant annular array, the multiple reinforcing ring grooves 106 form a circular interconnected structure. Reinforcing rings 2 made of heat-resistant stainless steel are installed within the reinforcing ring grooves 106. The cross-sectional shape of the reinforcing ring groove 106 matches the outer contour of the reinforcing ring 2. The reinforcing ring 2, embedded within the reinforcing ring groove 106, forms a clamping constraint. Under high temperature and mechanical vibration conditions, the reinforcing ring 2 maintains stability, providing a clamping effect on the refractory bricks 1 and enhancing the overall stability. On the one hand, an arc-shaped protrusion 102 is provided at one end of the arc-shaped brick body 101, and an arc-shaped groove 103 is provided at the other end. The cross-sections of the arc-shaped protrusion 102 and the arc-shaped groove 103 are adapted to each other in an arc-shaped structure. Multiple refractory bricks 1 are connected to the arc-shaped protrusions 102 of adjacent refractory bricks through the arc-shaped grooves 103 to form an annular masonry. The outer surface of the arc-shaped protrusion 102 and the inner surface of the arc-shaped groove 103 are closely fitted and matched, which further ensures the tightness and stability of the connection between the refractory bricks 1, prevents gaps, reduces the risk of molten steel leakage, improves thermal insulation performance, and reduces energy consumption.
