Refractory spinel products used for proportioning material
Description
The two main methods for synthesizing spinel are sintering and electrofusion. Most spinel materials are made of high-purity synthetic alumina and chemical-grade magnesium oxide, which are sintered in a shaft kiln and fused in an electric arc furnace.
Advantages of Spinel
- Wear resistance
- High temperature resistance
- Erosion resistance
- Small thermal expansion coefficient
- Good thermal stability
Application of Spinel
- Proportioning material
- Glass industry kiln
- Castable
- Cement rotary kiln
- Steel making
- Iron manufacturing
- Refractory material
