Durable brown corundum with high thermal stability and corrosion resistance, specially designed for manufacturing refractory products and high-heat applications.
Brown corundum is a premium-grade refractory manufactured through the high-temperature fusion of bauxite, iron filings, and coke in an electric arc furnace at over 2000°C. This process results in a dense, highly crystalline alumina with exceptional hardness, strength, and resistance to extreme temperatures. After cooling, the material is carefully crushed, screened, and graded into various sizes to meet specific industrial requirements.
In refractory applications, brown fused alumina is valued for its superior thermal stability, low porosity, and excellent resistance to chemical corrosion and mechanical wear. Its high alumina content, typically above 95%, ensures excellent performance in harsh environments, such as blast furnaces, cement kilns, and steel-making operations.
Brown corundum is widely used in the production of refractory bricks, castables, and monolithic linings. It provides exceptional durability in lining materials for furnaces, ladles, and crucibles, ensuring prolonged service life and optimal performance under extreme heat and pressure. Additionally, its ability to resist slag and thermal shock makes it an indispensable material in the refractory industry.
Choose best brown corundum for reliable, long-lasting refractory solutions that meet the demands of high-temperature industrial processes.
