Zircon Ram - Chemically Bonded Refractory Ramming Mix

VITCAS Zircon Ram – Chemically Bonded Refractory Ramming Mix 1750°C

VITCAS Zircon Ram is a high-strength, chemically bonded zircon-based refractory ramming mix developed for constructing and repairing compacted refractory linings. With a maximum service temperature of 1750°C / 3180°F, it is designed for demanding industrial environments involving molten metals, aggressive slags and molten glass.

Supplied in a semi-dry consistency with approximately 5% moisture content, Zircon Ram is formulated for installation by pneumatic ramming or vibration. Its zircon-rich composition provides high refractoriness, chemical stability and resistance to penetration by compatible molten materials, making it particularly suitable for foundry and glass furnace applications.

Key Features and Benefits

• High Temperature Resistance: Maximum service temperature of 1750°C / 3180°F.
• Zircon-Based Formulation: Refractory material offering high thermal stability and resistance to selected chemically aggressive environments.
• Chemically Bonded: High-strength formulation for compacted refractory lining applications.
• Semi-Dry Consistency: Approximately 5% moisture content, suitable for mechanical compaction.
• Resistance to Molten Materials: Designed for suitable applications involving molten metal, glass and slags.
• Low-Porosity Lining: Proper compaction helps reduce voids and material penetration.
• Industrial Durability: Suitable for demanding refractory linings exposed to high temperatures and chemical attack.

Applications

• Foundry Ladles: Constructing and repairing compatible refractory linings in molten metal handling equipment.
• Molten Metal Launders: Forming compacted refractory linings in channels used to transfer molten metals and alloys.
• Glass Tanks: Refractory lining and backing applications in glass melting installations.
• Glass Furnace Bottoms: Installation behind refractory bricks or blocks exposed to molten glass.
• Industrial Refractory Linings: Compacted sections in suitable high-temperature equipment requiring resistance to molten materials and slag attack.

Installation and Performance Considerations

Zircon Ram is designed for mechanical compaction by pneumatic ramming or vibration. The semi-dry mix must be placed and consolidated according to the specified refractory lining design to achieve suitable density and minimise voids.

For glass furnace applications, it is particularly suited to backing zones behind bricks or blocks in contact with molten glass. Material selection should account for operating temperature, glass or metal composition, slag chemistry and the required lining construction.

Please note: The 1750°C rating is the maximum service temperature, not an application temperature. Zircon Ram is intended for compacted refractory construction and repair; for localised hot or cold patching of existing refractory surfaces, VITCAS Zircon Patch may be more suitable. Installation and commissioning must follow the relevant technical specification.
