High-alumina refractory bricks with a high percentage of aluminum oxide (Al₂O₃) provide exceptional thermal and mechanical resistance at elevated temperatures. These bricks demonstrate stable performance against abrasion, impact, spalling, and thermal shock, while offering high resistance to slags and neutral or acidic chemical agents. Their dense structure, low porosity, and creep resistance make them ideal for use in steel, cement, and glass furnaces, blast furnaces, and heavy industries. Production in various dimensions, easy installation, and long service life are among their main advantages.
High-alumina refractory bricks with an engineered composition and a high percentage of Al₂O₃ are a reliable choice for demanding working conditions and extremely high temperatures. Featuring low porosity and excellent chemical and mechanical resistance, these bricks deliver long-lasting performance against abrasion, thermal shock, and slag penetration. Their dimensional stability reduces maintenance requirements and extends the service life of structures. Widely used in steel, cement, glass, and foundry furnaces, they combine easy installation with consistent quality, significantly enhancing the efficiency of industrial processes.
Alumina refractory bricks are a class of refractories with a high percentage of aluminum oxide (Al₂O₃) in their composition. Increasing the alumina content significantly improves the thermal and mechanical properties of these bricks, and the selection of the appropriate type for different furnaces is based on this factor. The high demand for alumina bricks is due to their ability to withstand extremely high temperatures, resistance to spalling, impact, abrasion, and pressure, as well as their favorable chemical resistance against acids and neutral slags at elevated temperatures. These products are typically produced and classified within the range of 50 to 90 percent alumina. Refractories with 50 percent alumina, characterized by high purity, low porosity, and excellent resistance to alkali attack and creep under load, are considered an ideal choice for firing kilns, glass tank regenerators, blast furnaces, carbon black furnaces, and the inner linings of steel-melting furnaces, offering stable and long-lasting performance.
High-alumina refractory bricks with a high percentage of Al₂O₃ not only withstand extremely high temperatures but also provide exceptional mechanical strength and thermal stability. These properties give them outstanding resistance to abrasion, impact, thermal shock, and spalling under harsh industrial conditions. Such characteristics make them an ideal choice for steel, cement, and glass furnaces as well as foundry units, extending service life and enhancing process efficiency.
