Q & A

Corundum, a crystalline form of aluminum oxide, is extensively used in high-temperature refractories due to its exceptional heat resistance and chemical stability. It possesses a high melting point of around 2050 degrees Celsius, making it suitable for applications in extreme temperature conditions. Corundum-based refractories are commonly employed in industries such as steel, glass, cement, and petrochemicals, where they are utilized for lining furnaces, kilns, and other thermal-processing equipment. The use of corundum ensures excellent resistance to thermal shocks, erosion, and corrosive environments, enhancing the durability and longevity of refractory linings. Additionally, corundum-based refractories exhibit low thermal conductivity, allowing for efficient heat management and conservation. Overall, the incorporation of corundum in high-temperature refractories ensures optimal performance and reliability in demanding industrial settings.

Chamotte is obtained by mining or extracting clay deposits, which are then crushed, ground, and sieved to obtain the desired particle size. The extracted chamotte is then mixed with other raw materials, such as binders and additives, to enhance its performance and workability. This mixture is then shaped into desired forms, such as bricks, tiles, or castables, using various techniques like molding, extrusion, or casting. After shaping, the chamotte products are dried and fired at high temperatures to achieve the desired refractory properties.

The refractory raw materials used in lining coke ovens include high-alumina bricks, fireclay bricks, silica bricks, magnesia bricks, and carbon bricks. These materials are chosen for their ability to withstand high temperatures and chemical reactions that occur during the coking process.
