Corundum Mullite Refractory Brick: Engineered for Extreme Performance
When your furnace operates above 1650°C, you need materials that won't let you down. Corundum Mullite Refractory Brick from TY Refractory delivers exactly that. Built from plate-shaped corundum and high-purity electric fused corundum, these bricks achieve exceptional refractoriness under load (RUL >1650-1700°C), superior high-temperature bending resistance, and minimal permanent linear change. With Al2O3 content ranging 75-92%, bulk density of 2.8-3.1 g/cm³, and cold crushing strength exceeding 80MPa, our bricks provide proven reliability for blast furnace ceramic cups and ceramic pads. Backed by TY Refractory's 30+ years of manufacturing expertise and over 20 patents, you're choosing a partner trusted by major steel groups worldwide.
Why Choose Our Corundum Mullite Bricks?
You face real challenges in your operations. Premature lining failure. Thermal shock cracking. Slag erosion eating through your investment.
Our product solves these problems through intelligent material design.
The secret lies in the microstructure. We create an interlocking network of acicular mullite crystals reinforced with dense corundum particles. This unique combination gives you the best of both worlds: the high-temperature strength of corundum with the superior thermal shock resistance of mullite.
Key Performance Advantages
Temperature Solidness You Can Trust
Your heater doesn't work at consistent temperatures. Fast variances crush ordinary refractories. Our bricks include a moo warm development coefficient (around 5.3 x 10^-6/°C), significantly lessening spalling hazard amid temperature cycling.
Chemical Resistance That Lasts
Aggressive slag and heater gasses continually assault your linings. We entirely control Fe2O3 substance underneath 0.5%, anticipating flux-induced corruption. Our bricks keep up basic keenness in both acidic and unbiased slag situations, as well as lessening airs wealthy in CO and H2.
Structural Judgment Beneath Pressure
High-temperature crawl causes disastrous disappointment. Our refractoriness beneath stack surpasses 1700°C, guaranteeing your lining keeps up its shape indeed beneath extraordinary warm weight.

Frequently Asked Questions
Q: Why choose our bricks over pure corundum bricks?
A: Pure corundum offers higher refractoriness, but our mullite phase delivers significantly better thermal shock resistance. You get fewer cracks and longer service life during temperature fluctuations.
Q: What's the maximum safe operating temperature?
A: Depending on the grade, you can safely operate between 1650°C and 1750°C in continuous service.
Q: How does iron content affect performance?
A: High iron acts as a flux, lowering the eutectic point and reducing chemical resistance. We keep Fe2O3 below 0.5% through rigorous quality control.
Q: Can these bricks handle reducing atmospheres?
A: Absolutely. They're highly stable in CO, H2, and other reducing environments common in petrochemical gasifiers.
Q: What about custom shapes and lead times?
A: Custom shapes require 4-6 weeks for production and quality verification. This careful process prevents internal micro-cracks that could compromise performance.
