Magnesia Bricks For Glass Kiln
Description
Magnesia bricks are required in the wall of the regenerator because it is resistant to the erosion of solid powder components in the kiln batching and alkaline gaseous medium.
Features
- High refractoriness.
- Good alkali slag resistance.
- Load softening start temperature is high.
