Corundum Refractories
Features
1.No pollution to glass liquid
2.Strong corrosion resistance
3.Good slag resistance
4.Low permannent liner change on reheating
5.Good mechanical property at high temperature
6.Good chemical stability
Application
High purity corundum brick is usually used in gasifier, ethylene generated furnace and ammonia decomposing furnace in petrochemical industry, carbon black reactor in chemical industry and high temperature kilns in refractories and ceramics industry . In addition, it is also adopted as high temperature interlayer between AZS ans basic bricks in order to avoid the reaction of interface at high temperature.
