Industry Knowledge of Corundum Refractory Brick

Corundum refractory brick is a type of refractory material that is widely used in high temperature environments such as metallurgy, ceramics, and petrochemical industries due to its excellent performance in terms of heat resistance, wear resistance, and chemical stability.

There are different grades of corundum refractory brick available, with the most common being high-alumina, chromium-corundum, and zirconium-corundum. These different grades are determined by the specific material used in their production, which affects their physical and chemical properties.

When it comes to the technical parameters of corundum refractory brick, there are several key factors to consider, such as the refractoriness, thermal shock resistance, compressive strength, and apparent porosity. Refractoriness refers to the temperature at which the material can withstand without deformation or failure, while thermal shock resistance measures its ability to withstand rapid changes in temperature without cracking or breaking. Compressive strength and apparent porosity are also important measures of the material's overall durability and resistance to damage.

In terms of production processes, corundum refractory brick is typically made using high-purity raw materials and a high-temperature sintering process. This involves mixing the raw materials into a specific composition, molding the mixture into the desired shape, and then sintering it at temperatures typically above 1700°C. This process ensures that the material has a uniform structure and excellent properties.

In conclusion, corundum refractory brick is a highly valuable material with a range of different applications across a variety of industries. Understanding its different grades, technical parameters, and production processes is essential for ensuring that the right material is selected for the job at hand, and that it performs at its best.
