High-alumina castable is a refractory material, which is mainly made of high-alumina silica clinker, clay, slag powder, limestone and other raw materials in a certain proportion, adding appropriate amount of water and binder, and is made through mixing, pouring, curing, baking and other processes. High-alumina castable is widely used in metallurgy, chemical industry, power and other industries due to its excellent refractory performance, mechanical properties and stability.
The main chemical indicators of high-alumina castable include: Al2O3 content, SiO2 content, Fe2O3 content, etc. Among them, Al2O3 content is an important indicator for measuring the refractory performance of high-alumina castable, which is generally required to be above 65%. The physical indicators mainly include: bulk density, compressive strength, flexural strength, wear resistance, alkali resistance, etc. These indicators are directly related to the performance of high-alumina castable in practical applications.
1. Excellent refractory performance: The high-alumina castable has a high Al2O3 content, which makes it have high refractory performance and can be used for a long time in high temperature environments.
2. Good mechanical properties: The physical indicators of high-alumina castables such as flexural strength and compressive strength are high, and they can withstand large mechanical loads.
3. Good stability: The high-alumina castable has excellent wear resistance, alkali resistance and other indicators, and can maintain stable performance in harsh environments.
4. Convenient construction: High-alumina castables can be directly cast and constructed, which simplifies the construction process and reduces the difficulty of construction.
5. Economical: Compared with traditional refractory bricks, high-alumina castables have lower costs and higher economical efficiency.
