Product Introduction:
Magnesia spinel bricks are refractory products made of periclase and magnesia alumina spinel, designed to enhance the heat stability of traditional magnesia bricks.
Application:
Primarily used in the burning zone and transition zone of cement kilns, as well as various industrial furnaces.
Features:
- Excellent heat stability
- Superior anti-stripping performance compared to direct bonded magnesia chrome brick
- Abrasion resistant
- High refractoriness under load
