Corundum Bricks/Corundum Mullite Bricks
Product Information
Corundum bricks are a kind of aluminum-silicon refractory product with corundum as the main crystal phase. By adding some other chemical mineral components, it can form composite products, such as zirconium corundum bricks, chrome corundum bricks, titanium corundum bricks, etc.
Corundum bricks have the characteristics of high melting point, good slag resistance, high strength and hardness, and abrasion resistance.
Classification: Corundum/Zirconium Corundum/Chrome Corundum/Chrome Zirconium Corundum Bricks, etc.
Features
Corundum Bricks: Corrosion resistance, abrasion resistance and high temperature strength, refractoriness under load, creep and other thermodynamic properties.
Chrome Corundum Bricks: Excellent thermal vibration stability and high temperature creep performance, and excellent corrosion resistance.
Zirconium Corundum Bricks: High mechanical strength, good thermal stability, small high-temperature creep, stable chemical properties, and good acid and alkali corrosion resistance.
Corundum mullite bricks have good high temperature strength, high temperature creep resistance, thermal shock resistance and erosion resistance.
