Industry Knowledge of Corundum Refractory Castables

Corundum refractory castables are widely used in high-temperature furnace linings and other harsh industrial environments due to their outstanding refractory properties. Let's explore the industry knowledge of corundum refractory castables, including their classification, technical parameters, and production processes.

Corundum refractory castables are classified into different grades based on their composition and performance levels. Classifications include low cement, ultra-low cement, cement-free, and other types.

Technical parameters play an important role in ensuring the quality and performance of corundum refractory castables. The main technical parameters include bulk density, apparent porosity, compressive strength, flexural strength, thermal shock resistance, and thermal conductivity. These parameters are measured and monitored during the production process to ensure quality control.

The production of corundum refractory castables typically involves several stages, including raw material preparation, mixing, molding, drying, and firing. Raw materials such as corundum, alumina, cement, and other additives must be carefully selected and mixed in specific proportions to achieve the desired properties. During the molding process, the mixture is formed into blocks or shapes, which are then dried and fired at high temperatures. The firing process improves the mechanical and refractory properties of the castables, making them suitable for high-temperature applications.

Corundum refractory castables are an essential material for the modern industry. With their excellent heat resistance and durability, they help to maintain the performance and efficiency of high-temperature furnaces and other equipment. The classification, technical parameters, and production processes are key factors to consider when selecting and using corundum refractory castables. Overall, the corundum refractory castables industry is vibrant and dynamic with continued advancements in science and technology, driving the growth and development of refractory industries worldwide.
