Description

Technical Field

[0001] This invention relates to the field of refractory materials technology, and in particular to an erosion-resistant refractory material suitable for dry quenching furnaces and its preparation method. Background Technology

[0002] The dry quenching furnace is the core equipment of the dry quenching process in the metallurgical industry. It achieves cooling of red-hot coke and recovery of waste heat through heat exchange between inert gas and hot coke, while simultaneously recovering over 80% of the sensible heat for power generation. It offers advantages such as energy saving, environmental protection, and improved coke quality. The refractory materials for the dry quenching furnace need to operate under extreme conditions, requiring excellent thermal shock resistance, superior wear resistance, sufficient high-temperature strength and load softening temperature, good resistance to chemical attack, and high-temperature volume stability.

[0003] The selection and performance improvement of refractory materials for dry quenching furnaces is a systematic project. The core lies in accurately selecting materials based on the characteristics of each part's operating conditions, and comprehensively improving service life and reliability through optimized formulation, improved structural design, ensuring masonry quality, and stable operation. CN111548164A discloses a continuously self-toughening nitride-bonded silicon carbide refractory material, with silicon carbide as the main crystalline phase, nitride as the binding phase, and zirconium-containing substances dispersed within the nitride binding phase. The nitride content in this continuously self-toughening nitride-bonded silicon carbide refractory material is 10-25%, the zirconium-containing substance content is 1-8%, and the silicon carbide content is 70-82%. This invention fully utilizes the high flexural strength at both normal and high temperatures of nitride-bonded silicon carbide refractory materials, improving their oxidation resistance and thermal shock resistance, enhancing the overall integrity of the furnace body, and extending its service life. However, oxidation of the zirconium-containing substances may cause volume changes, leading to material damage. CN104446561A discloses a high-strength silicon carbide refractory material for dry-quenching coke ovens and its preparation method. The raw materials, by percentage, include: 70-80% black silicon carbide fine powder, 18-25% elemental silicon fine powder, 1-5% silica sol, and 1-3% binder. This invention allows the formation of a thin, dense layer on the surface during firing, which not only reduces further oxidation of silicon carbide but also possesses self-healing properties. However, it does not address the strength degradation of the refractory material during service.

[0004] There is still a need to provide high-performance, erosion-resistant refractory materials suitable for dry quenching furnaces. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides an erosion-resistant refractory material suitable for dry quenching furnaces, comprising, by mass percentage, 70%~90% silicon carbide, 3%~5% titanium disilicide, 5%~25% silicon nitride, and 0.5%~2% zirconium silicate; The method for preparing zirconium silicate includes, A 1-3 mol / L silicate solution and a 1-3 mol / L zirconium salt solution are added to a mixed solution containing 0.1-0.5 mol / L mineralizing agent and 0.05-0.2 mol / L complexing agent to form a reaction system. The reaction is carried out, and the insoluble matter is collected after the reaction is completed. The volume ratio of silicate solution, zirconium salt solution and mixed solution is 0.8-1:0.8-1:1.5-2. Zirconium silicate was obtained by heat treatment of the insoluble material.

[0006] Silicon carbide possesses many excellent properties, such as good wear resistance, creep resistance, and oxidation resistance, high thermal conductivity, and a low coefficient of thermal expansion, making it a leading candidate material for high-temperature structural applications in heat engines, heat exchangers, and many other devices. Titanium disilicide is renowned for its excellent high-temperature stability, outstanding oxidation resistance, and creep resistance, making it a crucial high-temperature structural material. Silicon nitride exhibits extremely high strength, hardness, excellent thermal shock resistance, and oxidation resistance at high temperatures, while maintaining excellent wear resistance and chemical stability. Zirconium silicate, an island-like orthosilicate compound, has a theoretical composition of 67.1% zirconium dioxide and 32.9% silicon dioxide, and possesses advantages such as a high melting point, high thermal stability, high chemical stability, and high thermal shock resistance.

[0007] This invention uses silicon carbide, titanium disilicide, and silicon nitride as the main components of the refractory material. The atmosphere of the dry quenching furnace is mainly nitrogen, supplemented by carbon monoxide, carbon dioxide, etc. Studies have shown that titanium disilicide undergoes a nitriding reaction at a high temperature of approximately 950°C in a nitrogen atmosphere, forming titanium nitride and silicon. As the temperature continues to rise and the reaction time extends, silicon continues to nitride, forming silicon nitride. Silicon nitride fills the pores inside the composite material, thereby improving the material's strength and toughness. However, due to limitations in the refractory material preparation temperature and the actual application temperature in the dry quenching furnace, the titanium disilicide nitriding reaction may be incomplete, resulting in silicon not being completely converted into silicon nitride. The residual silicon is brittle, lacks ductility, and is prone to fracture, potentially reducing the material's strength. Therefore, this invention also adds zirconium silicate to the refractory material formulation. Zirconium silicate can lower the nitriding temperature of silicon, promote the formation of silicon nitride, fill pores, and enhance the material's strength.

[0008] Furthermore, the mineralizing agent includes at least one of potassium chloride, sodium chloride, potassium fluoride, sodium fluoride, and ammonium fluoride.

[0009] Furthermore, the complexing agent is glutamic acid or glutamate.

[0010] Furthermore, the mixed solution also contains 0.01~0.03 mol / L neodymium salt.

[0011] The microstructure of zirconium silicate can be effectively controlled by adding mineralizers and complexing agents, thus optimizing the distribution of silicon nitride. Neodymium doping of zirconium silicate can further promote this effect.

[0012] It should be noted that the present invention does not strictly limit the types of silicates, zirconium salts, and neodymium salts, and can select them as needed. The solvents for dissolving silicates, zirconium salts, as well as mineralizing agents, complexing agents, and neodymium salts, do not strictly limit the types, and can, for example, be at least one of water, ethanol, acetone, etc., preferably water.

[0013] Furthermore, the reaction is carried out at 60-80°C for 5-8 hours, and the pH of the reaction system is maintained at 2.5-3.5 during the process.

[0014] Furthermore, the heat treatment is carried out at 700~950℃ for 1~3 hours.

[0015] Furthermore, the silicon carbide is obtained by mixing 1-3 mm silicon carbide, 0.09-1 mm silicon carbide and 20-100 μm silicon carbide.

[0016] Furthermore, the silicon nitride has a particle size of 50~100μm.

[0017] This invention also provides a method for preparing the above-mentioned erosion-resistant refractory material suitable for dry quenching furnaces, comprising, Titanium disilicide, silicon nitride, and zirconium silicate were ball-milled to obtain the matrix; The matrix, silicon carbide and binder are mixed to obtain mud, which is then pressed, dried and fired to obtain an erosion-resistant refractory material suitable for dry quenching furnaces.

[0018] Furthermore, the binder includes at least one of polyvinyl alcohol and phenolic resin. The binder, used for mixing and molding, is not included in the composition of the refractory material and is generally added at 3% to 15% of the raw materials.

[0019] Compared with the prior art, the present invention has the following beneficial effects: This invention uses silicon carbide, titanium disilicide, and silicon nitride as the main components of refractory materials, supplemented by zirconium silicate, which has a high melting point, high thermal stability, high chemical stability, and high thermal shock resistance. The introduction of zirconium silicate can reduce the nitriding temperature of silicon produced by the decomposition of titanium disilicide, promote the formation of silicon nitride in the pores of the material, fill the pores, strengthen the strength of the material, reduce the apparent porosity, and improve the corrosion resistance.

[0033] Test example: The microstructure of zirconium silicate prepared in Examples 1-2 and Comparative Examples 1-2 was observed using scanning electron microscopy. The results are as follows: Figures 1-4 As shown. From Figure 1 and Figure 2 As can be seen, the zirconium silicate of Examples 1 and 2 has a regular morphology, is polyhedral, and basically does not agglomerate, which also indicates that the incorporation of neodymium did not affect the structure of zirconium silicate. Figure 3 The results showed that the absence of the complexing agent glutamic acid affected the structure of zirconium silicate. In Comparative Example 1, the zirconium silicate was uneven in size, exhibiting irregular lumps and obvious agglomeration. In Comparative Example 2, compared to Comparative Example 1, ammonium fluoride was not added during the preparation of zirconium silicate. Figure 4 The results show that zirconium silicate exhibits a long, blocky structure with significantly increased grain size. These results indicate that the presence of the mineralizing agent ammonium fluoride and the complexing agent glutamic acid optimizes the structure of zirconium silicate and reduces grain size.

[0034] The room-temperature flexural strength and 1400℃ high-temperature flexural strength of the refractory materials prepared in the examples and comparative examples were tested according to national standards GB / T3001-2017 "Test Method for Flexural Strength of Refractory Materials at Room Temperature" and GB / T3002-2017 "Test Method for Flexural Strength of Refractory Materials at High Temperature". The bulk density and apparent porosity of the refractory materials were tested according to national standard GB / T 2997-2015 "Test Method for Bulk Density, Apparent Porosity and True Porosity of Dense Shaped Refractory Products". These test results are shown in Table 1. Table 1:

[0035] As can be seen from the test results in Table 1, the embodiments of the present invention have higher room temperature flexural strength, high temperature flexural strength, bulk density, and lower apparent porosity.

[0036] The microstructure of the refractory materials of Examples 1-2 and Comparative Examples 1-3 after the flexural strength test was also observed using a scanning electron microscope, as shown below. Figures 5-9 As shown. Figure 9 The cross-section of Comparative Example 3 contained visible particles, which were attributed to silicon produced by the decomposition of titanium disilicide. This silicon did not react with nitrogen to form silicon carbide, thus remaining at the cross-section. Figure 5 and Figure 8 In the cross-sections, fibrous and elongated species were observed, indicating the formation of silicon carbide. This also demonstrates that zirconium silicate can lower the nitriding temperature of silicon, promote the formation of silicon nitride, fill pores, and enhance the strength of the material. Specifically, the cross-sections of Examples 1 and 2 exhibit a continuous fiber network structure. This structure effectively fills the pores inside the refractory material, enhancing its strength. Simultaneously, the dense fiber structure also improves the refractory material's resistance to the erosion of impurity ions.

[0037] The alkali erosion resistance of the refractory materials prepared in the examples and comparative examples was tested using the molten alkali crucible method in the national standard GB / T 14983-2008 "Test Method for Alkali Resistance of Refractory Materials". The results are shown in Table 2. Grade 1 is the best, and a higher grade indicates a larger crack width in the refractory material after the test. Table 2:

[0038] The test results in Table 2 also show that the embodiments of the present invention have higher resistance to alkali corrosion.

[0039] In summary, this invention uses silicon carbide, titanium disilicide, and silicon nitride as the main components of the refractory material, supplemented by zirconium silicate, which has a high melting point, high thermal stability, high chemical stability, and high thermal shock resistance. The introduction of zirconium silicate can reduce the nitriding temperature of silicon produced by the decomposition of titanium disilicide, promote the formation of silicon nitride in the pores of the material, fill the pores, strengthen the strength of the material, reduce the apparent porosity, and improve the corrosion resistance.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
