Description
Zirconium Corundum Ramming Mass is crafted from fused zirconium corundum granules through an oxidation process, supplemented with a small quantity of additives. This material demonstrates the unique property of hardening at ambient temperatures, while exhibiting robust strength at elevated temperatures, minimal thermal expansion and shrinkage, and substantial resistance to erosion by molten glass. It stands as the optimal choice for forming a sealing layer at the base of a glass furnace molten pool.
Attributes of Zircon Corundum Ramming Mass:
- Exceptional refractoriness, particularly under load.
- Elevated density, coupled with low porosity.
- Notable resistance against slag and corrosion.
- Demonstrates high strength and wear resistance.
- Exhibits impressive resistance to flaking.
- Maintains stability in the face of thermal shocks.
- Resistant to scouring.
- Retains robust strength at high temperatures.
Applications of Zircon Corundum Ramming Mass: This material finds extensive utility in a range of applications, including glass furnace bottoms, ladles, circulating fluidized bed boilers, and various other fields.
