Densification and sintering composite high zirconium brick (use temperature 0-1720 ℃, density 5.10 g/(25 ℃))
The idea of the new type of high-zirconium ceramic multifunctional composite brick is based on the shortcomings of current fused high-zirconium bricks such as corrosion resistance and erosion resistance, large kiln construction volume, high energy consumption and other shortcomings, using an integrated combination of three layers of different materials It has the characteristics of cutting processability and integrated sintering interface fusion. It has good thermal insulation, low gradient thermal stress, and different properties of corrosion resistance and erosion resistance of the working layer in contact with the glass solution. It is divided into three-layer combinations, which are working Layer, safety layer and insulation layer.
It is preset that the thickness of the insulation layer is 150 mm, the thickness of the safety layer is 150 mm, and the thickness of the working layer is 20-80 mm, which can be adjusted according to user needs.
Schematic diagram of high zirconium ceramic multifunctional composite brick structure
Adopt three layers of different materials to separate and bond into an integrated combination method, and use gradient composite technology for two or more materials to make the composition and structure change continuously from one side to the other side to reduce Small and overcome the performance mismatch phenomenon of the bonding part, to achieve the disappearance of the internal interface, the performance of the material also presents a gradient change corresponding to the change of the composition and structure.
The working layer adopts zirconium-based solid solution materials to avoid the defects of stable zirconium stabilization rate aging and decay. The combination of micron and nanometer powders has zirconium content ranging from 80-94%, achieving sintering 99% densification, and porosity close to 0. The temperature resistance reaches 1750 degrees Celsius for the purpose of long-term use, in order to deal with the long-term constant glass solution erosion and scouring conditions of the working layer, and is committed to achieving 2 times or more than the life of the current 41# fused brick.
The protective layer is made of high-purity alumina raw materials or zirconium silicate. Its function is reflected in the long-term use safety guarantee after the working layer. At the same time, it has a good thermal gradient reduction function.
The insulation layer is made of fiber materials that can withstand temperatures up to 1650 degrees Celsius, and its thermal conductivity is low. When the design thickness is used at 100-150 mm, when the heating temperature reaches 1400 degrees Celsius, the surface temperature is lower than 60 degrees Celsius. (Optional according to the situation)
Targeted application solutions for high-calcium, high-sodium, high-fluorine, high-barium, and high-boron glass
According to different types of glass, according to its characteristics, you can choose:
Calcium zirconate solid solution (use temperature 0-1720℃, melting point 2250-2550℃, density 5.11 g/(25 ℃))
Barium zirconate solid solution (use temperature 0-1720°C, melting point: 2500°C, density: 5.52g/ml (25°C))
Yttrium-zirconium solid solution (use temperature 0-1720℃, melting point: 2850℃, density: 4.80g/ml (25 ℃))
Wait for the targeted use of the above products to promote them to reduce interface damage caused by chemical reactions at high temperatures, thereby improving the service life and the safety of glass products. Therefore, compared with traditional materials, targeted application of materials to promote the increase of life It is also one of the very effective methods.
Stable zirconium products, use temperature 1800-2200℃, density 5.10 g/(25 ℃)
The application temperature range is 0 degrees Celsius to 2700 degrees Celsius, the application environment is: air, vacuum, protective atmosphere, etc., the application fields are special glass manufacturing, titanium alloy smelting, etc.;
The splicing gap is 0.2-0.5 mm, and it can be used as a gap bonding scheme. The linear expansion rate of 0-1000℃ is 5.5×10-6,0-1000℃ and the relative length change rate is 0.08%.
After the use temperature exceeds 1700°C, conventional high-zirconium materials can no longer meet the long-term use requirements after 1750°C due to their load softening, liquid phase precipitation, and active chemical reactions. After 1750°C, traditional high-zirconium materials are used. Materials such as AZS will accelerate damage and erosion. Therefore, stable high zirconium materials or solid solution materials must be used in the ultra-high temperature environment after 1750 ℃ to meet the conditions of long-term ultra-high temperature use and the conditions that are not easy to react with other active elements. When the temperature is higher than 1750°C for long-term contact with glass solutions or other metal solutions, the theoretical life of high zirconium materials with a temperature higher than 1800°C-2200°C can be increased by 2-3 times.
