Industry Knowledge of Corundum Refractory Brick

Corundum refractory brick is a high-grade refractory material made of high purity corundum as the main raw material. It is widely used in high-temperature furnaces and kilns due to its excellent performance in resisting high temperature, corrosion, and wear.

There are two grades of corundum refractory brick: ordinary corundum refractory brick and high-purity corundum refractory brick. The former is mainly used in general industrial fields while the latter is mostly used in high-precision industries, such as aerospace, electronic, and optical industries.

The technical parameters of corundum refractory brick include high-temperature resistance, thermal shock resistance, chemical stability, and mechanical strength. The high-temperature resistance of corundum refractory brick can reach up to 1800℃, and its thermal shock resistance is excellent due to its low thermal expansion coefficient. Moreover, corundum refractory brick has high chemical stability, which can be used in acidic, alkaline, and neutral environments.

The production process of corundum refractory brick is complicated and demanding. High-quality corundum raw materials are selected, crushed, and ground into fine powders. Then, the powders are mixed with binders and additives to form a mud, which is molded into shape and dried. After that, the green body is sintered at high temperatures, and the final product is obtained by precision machining and quality inspection.

In conclusion, corundum refractory brick is a high-grade refractory material with excellent performance. It plays a vital role in various industries, and its market prospects are promising. With the continuous advancement of technology, the production process of corundum refractory brick will be further improved, making it more efficient and economical.
