Why Corundum Refractory Bricks Maintain Stability in High-Temperature Acid-Alkali Environments: A Technical Analysis

This article explores the reasons behind the structural stability and chemical corrosion resistance of corundum refractory bricks in high-temperature acid and alkali environments. It analyzes their high alumina content (over 90%), excellent cold crushing strength, abrasion resistance, and the technical advantages of sintering and fusion casting manufacturing processes, demonstrating their superior performance at temperatures exceeding 1700°C. Practical application cases in metallurgy, glass, and other industries illustrate how corundum bricks effectively resist erosion by acid-alkali slags and melts, extending equipment service life and enhancing operational efficiency. It provides a scientific basis for material selection for engineers and procurement decision-makers, aiding enterprises in achieving business growth and competitive advantage.
