Castable can be classified by the raw materials (high alumina, corundum, silicon carbide), bulk density, refractoriness, acid-base properties and other many ways. Main factors that affect refractory castable performance can be following situations.
1. Quality, content, impurities and stability of refractory materials.
2. Ratio of refractory aggregate and powder, the finess.
3. Binding agent (model, label type and amount).
4. Raw material mixing and amount and water-material ratio.
5. PH value.
6. Refractory castable construction, maintenance and refractory castable baking temperature and seasonal variations (construction temperature).
7. Castable shelf life.
8. Production processes and operations.
9. Castable various physical and chemical properties and physical and chemical indicators (volume density, porosity, flexural compressive strength, load softening temperature, linear change, among other factors).
10. Using environment.
