Selection Guide for Refractory Bricks in High-Temperature Acid-Base Corrosive Environments: An In-Depth Analysis of the Erosion Resistance of Corundum Bricks

In high-temperature acid-base corrosive environments, the selection of refractory bricks directly determines the lifespan and operating efficiency of kilns. This article delves into the core advantages of corundum refractory bricks, including an alumina content exceeding 90%, high cold crushing strength, strong wear resistance, and a refractoriness exceeding 1700°C. It also compares the impact of two processes - sintering and melting - on performance. Through real application scenarios in industries such as metallurgy and glass, it reveals how corundum bricks effectively resist acid and alkaline slag erosion, reduce downtime, and extend equipment service life, helping engineers and procurement decision-makers make scientific material selections to enhance production stability and economic benefits.
