Product introduction of ladle refractory castable
Ladle refractory castable is made of high purity fused steel jade as the main material, and the matrix is mixed with high purity spinel, and add appropriate amount of binder, admixture (dispersant, water reducing agent).
Advantages of ladle refractory castable
Ladle refractory castable has the advantages of good slag resistance and stripping resistance, high volume stability, high strength and short sintering time.
Application of ladle refractory castable
- Steel furnace
- Ironmaking furnace
- Glass kiln
- Cement kiln
- Ceramic tunnel kiln
