What are Ceramic Foam Filter Sheets? Ceramic foam filter sheets are porous ceramic materials made primarily from alumina, silicon carbide, or zirconium oxide. They possess a three-dimensional, interconnected open-pore structure, resembling a sponge in appearance. Their porosity is typically between 75% and 90%, with uniform … 続きを読む

The boiler ash chamber is a critical component of the boiler system, subjected to high temperatures, ash erosion, and frequent thermal cycles. Therefore, it demands high strength, wear resistance, and thermal stability from refractory materials. Using refractory castables for solid brick forming is a mature … 続きを読む

High alumina cement (HAC), also known as calcium aluminate cement, is a specialized hydraulic binder made from alumina-rich raw materials. With an alumina content typically between 40% and 80%, it offers outstanding heat resistance, rapid strength development, and strong durability in corrosive environments. These characteristics … 続きを読む

Andalusite bricks are high-performance refractory bricks widely used in high-temperature industries such as metallurgy, glass, and ceramics due to their excellent high-temperature resistance. Their temperature resistance can reach 1700℃, mainly due to the material’s chemical composition, crystal structure, and advanced firing process. Firstly, from a … 続きを読む

I. Introduction to Refractory Materials Refractory materials are inorganic non-metallic materials that maintain strength and stability at high temperatures. They are widely used in metallurgy, cement, power, petrochemical, and environmental protection industries. Main types include high-alumina bricks, clay bricks, refractory castables, refractory cement, insulating bricks, … 続きを読む

During the manufacturing process of laser cutting machines, the high-temperature areas and heat treatment stages of the equipment place extremely high demands on refractory materials. To ensure long-term and stable operation of the equipment, mullite insulation bricks or high-alumina bricks are often used as thermal … 続きを読む

In the lining construction of industrial furnaces and high-temperature equipment, castables are widely used due to their ease of construction, good integrity, and durability. Refractory castables and insulating castables are two common types. Although their names are similar and they are often used together in … 続きを読む
