Magnesia Iron Spinel Brick Introduction
Magnesia iron spinel refractory bricks adopt the high purity magnesia and alumina iron spinel brick as the main material, through reasonable gradation, high pressure molding, strict control of firing temperature and burning atmosphere, the product has good flexibility and thermal shock stability. No hexavalent chromium pollution, used in cement kiln firing zone.
Magnesia Iron Spinel Brick Properties
- High pressure resistance
- Excellent thermal shock stability
- Good thermal creep resistance
- anti-resistance
- Anti-erosion
- High refractoriness under load
