GRADE DATA
Technical specification
Catalogue reference
Reference values for initial comparison. Confirm the selected grade and test methods for an order. Refractoriness and RUL are not continuous service-temperature ratings.
| Property | GM-1650 | GM-1680 |
|---|---|---|
| Al₂O₃ (%) | ≥63 | ≥65 |
| SiC + SiO₂ (%) | ≥30 | ≥30 |
| RUL at 0.2 MPa (°C) | ≥1650 | ≥1680 |
| Bulk density (g/cm³) | ≥2.60 | ≥2.65 |
| Apparent porosity (%) | ≤18 | ≤18 |
| Cold crushing strength (MPa) | ≥80 | ≥100 |
| Room-temperature abrasion loss (cm³) | ≤4.0 | ≤4.0 |
Parameters to include in your specification
- Chemical composition and impurity limits
- Bulk density, apparent porosity and cold crushing strength
- Refractoriness under load: load, endpoint and method
- Permanent linear change: temperature and holding time
- Dimensions, tolerances and joint design
