Corundum Mullite Brick: High Performance Refractory for Industrial Kilns
Introduction
Corundum mullite brick is a premium refractory product that takes corundum and mullite as its main crystalline mineral phases. Manufactured through precise batching, molding and high-temperature sintering processes, it perfectly merges the outstanding high-temperature structural stability of corundum and the superior thermal shock resistance of mullite. Compared with ordinary high-alumina bricks, this material can withstand harsher working environments with sharp temperature changes and long-term high-temperature loading. It has become a preferred refractory lining material for many heavy-duty industrial thermal equipment.
Key Performance Features
- High refractoriness and high load softening temperature, maintaining stable structure under sustained high-temperature loads
- Low high-temperature creep rate, with minimal deformation after long service at elevated temperatures
- Excellent thermal shock resistance, less cracking and spalling during rapid heating and cooling cycles
- Good chemical stability, strong resistance to erosion from high-temperature flue gas and weak slag
- Compact and uniform microstructure, stable volume after repeated temperature fluctuations
Typical Application Scenarios
Corundum mullite bricks are widely used for the lining of various high-temperature industrial kilns and furnaces. Common application sites include hot blast stoves in the iron and steel industry, ceramic roller kilns and shuttle kilns, metallurgical heating furnaces, petrochemical thermal furnaces and some waste incineration equipment. It is especially suitable for furnace zones that face frequent temperature rise and fall, where refractory linings are easy to peel and fail prematurely.
