Fused refractory material---Fused zirconium corundum brick

Fused refractory materials, especially fused zirconium corundum bricks, are an indispensable and important component in high-temperature industries. This material has been widely used in metallurgy, ceramics, glass and other industries due to its excellent high temperature resistance, excellent corrosion resistance and high mechanical strength.

The preparation of fused zirconium corundum bricks requires a precise electrofusion process. In an electric furnace, high-quality raw materials such as alumina, zirconia, etc. are melted at high temperatures, and then the melt is homogenized and densified by controlling the temperature and pressure. Finally, after cooling and solidification, the fused zirconium corundum brick is obtained.

Fused zirconium corundum bricks have extremely high refractoriness and can remain stable for a long time in high temperature environments. In addition, it has strong corrosion resistance and can resist the erosion of highly corrosive media such as molten metal and molten glass. At the same time, the material also has good thermal shock stability and can withstand rapid changes in temperature without cracking.

Due to its excellent performance, fused zirconium corundum bricks are often used in key parts such as blast furnaces, converters, electric furnaces, and glass kilns in the metallurgical industry to ensure the long-term use of furnace linings. In the ceramic industry, it is used on the top and walls of high-temperature kilns to extend the service life of the kiln. In addition, in the glass industry, fused zirconium corundum bricks are also used as key refractory materials for glass furnaces.

With the continuous advancement of high-temperature industry, the requirements for refractory materials are becoming higher and higher. In the future, research on fused zirconium corundum bricks will focus more on improving their thermal shock resistance, corrosion resistance and service life. At the same time, environmental protection and sustainable development will also become important research directions in the field of refractory materials.

The fused zirconium corundum brick, as an important fused refractory material, plays an irreplaceable role in high-temperature industry. With the continuous advancement of technology and the expansion of application fields, its performance will be further improved, providing strong support for the development of high-temperature industry.
