1. High refractoriness.
2. High strength resistance
3. Low thermal conductivity
4. Good thermal-shock performance
Features:
Fired and produced by super high alumina primary materials and light ball sintered with high strength, little after line change and low thermal conductivity.
Applications:
Using temperature is 1400–1500°C , can directly contact with flame. It is widely applied to metallurgy, electric power, petroleum, chemicals, ceramics, glass and other industrial furnaces.
