VITPLAST 85P - Chemically Bonded Mouldable Refractory

VITCAS Vitplast 85P – High Alumina Plastic Mouldable Refractory 1700°C

VITCAS Vitplast 85P is a chemically bonded, high-alumina plastic mouldable refractory developed for forming and maintaining specialised refractory sections in electric induction furnaces. With a maximum service temperature of 1700°C / 3100°F, it combines high refractoriness, low shrinkage and excellent ramming properties for demanding metal melting and casting operations.

Containing approximately 84% alumina (Al₂O₃), Vitplast 85P offers high-temperature stability and good dimensional control when correctly installed. Its mouldable consistency allows the material to be shaped and consolidated by pneumatic ramming or hand ramming, making it particularly suitable for refractory capping and furnace spout details.

Key Features and Benefits

• High Temperature Resistance: Maximum service temperature of 1700°C / 3100°F.
• High Alumina Content: Approximately 84% Al₂O₃ for demanding industrial refractory applications.
• Chemically Bonded Formulation: Develops a strong refractory structure within suitably designed furnace installations.
• Excellent Ramming Properties: Workable plastic consistency suitable for pneumatic or manual compaction.
• Low Shrinkage: Helps maintain dimensional stability during drying and high-temperature operation.
• Mouldable Construction: Suitable for forming specialised refractory profiles and compacted furnace details.
• Ready to Use: Supplied as a prepared plastic refractory material for direct placement and ramming.

Applications

• Electric Induction Furnace Capping: Forming and maintaining compatible refractory capping sections around induction furnace openings.
• Induction Furnace Spouts: Constructing and repairing shaped refractory spout sections used in molten metal pouring operations.
• Foundry Melting Equipment: Specialist refractory details in compatible ferrous and non-ferrous metal melting installations.
• Refractory Maintenance: Localised reconstruction of suitable capping and spout profiles where a rammed, chemically bonded refractory is specified.

Application and Performance Considerations

Vitplast 85P is intended for rammed refractory construction. The material should be placed into a suitably prepared area and thoroughly consolidated using an appropriate pneumatic rammer or hand-ramming method to achieve the required shape and density.

For induction furnace applications, the refractory composition, repair geometry, mechanical support and exposure to molten metal or slag must be considered. Drying and commissioning procedures should follow the manufacturer's instructions and the furnace operator's approved refractory maintenance specification.

Please note: The 1700°C rating refers to maximum service temperature, not permissible application temperature. Vitplast 85P is a specialist plastic refractory for compacted furnace details, not a thermal insulation product or a substitute for repairs to damaged induction coils or structurally unsound furnace linings.
