Differences between Sintered Corundum Bricks and Fused Corundum Bricks: Practical Impacts of Manufacturing Processes on High-Temperature Adaptability

This article delves into the core differences between the manufacturing processes of sintered corundum bricks and fused corundum bricks and their practical impacts on adaptability to high-temperature working conditions. Focusing on high-quality corundum refractory bricks with an alumina content of over 90%, it starts from technical indicators such as cold crushing strength, wear resistance, and fire-bearing capacity above 1700°C. Combining application scenarios in the metallurgy, glass, and ceramic industries, it elaborates on how different processes endow products with distinct performance advantages. Through professional technical interpretations and real - world cases, it helps industry decision - makers select materials accurately, enhance equipment durability, reduce downtime, and achieve a dual improvement in enterprise competitiveness and economic benefits.

Why Metallurgical Furnaces Prefer Alumina Content Above 90% in Corundum Refractory Bricks

In high-temperature metallurgical furnace applications, standard high-alumina bricks (typically <85% Al₂O₃) often fail prematurely due to acid-base corrosion, poor wear resistance, and short service life. Corundum refractory bricks—featuring over 90% alumina content and a dominant corundum phase—deliver 30%+ higher cold crushing strength, fire resistance exceeding 1700°C, and significantly enhanced erosion resistance. This technical advantage directly addresses common industry pain points: frequent lining damage and costly downtime. Learn how crystalline structure, manufacturing process (sintered vs. fused), and real-world performance in steelmaking and glass melting environments make high-purity corundum bricks the optimal choice for extended equipment life and reduced maintenance costs.
