Description
Magnesia alumina spinel is using industrial alumina or natural bauxite and high purity caustic magnesia powder as raw materials.It is an important aggregate used to enhance refractory properties.With the features of good erosion, abrasion, spalling and slagging resistance,perfect thermal shock resistance and high heat-resistance, it is the optimal material in producing magnesia-alumina spinel brick , ladle brick , ladle castable, etc.
Advantages of Spinel
- Wear resistance
- High temperature resistance
- Erosion resistance
- Small thermal expansion coefficient
- Good thermal stability
Application of Spinel
- Electric stove roof
- Proportioning material
- Glass industry kiln
- Castable
- Cement rotary kiln
- Steel making
- Iron manufacturing
- Refractory material
