REFRACTORY SHEET BOARD TYPE RS-1200

(PDF VERSION)

GENERAL INFORMATION

General Information

ZIRCAR Refractory Sheet Type RS-1200 is a high strength composite designed for use as thermo-mechanical and electrical insulation in applications with temperatures as high as 1300C(2372F). RS-1200 is a combination of strong reinforcing fibers tightly bound in an alumina ceramic matrix. RS-1200 is completely inorganic and contains no asbestos or RCF fibers. RS-1200 exhibits greater refractoriness and homogeneity than other reinforced alumina matrix composite products and can be readily machined to tight tolerances with conventional carbide tooling.

SUGGESTED APPLICATIONS

  • Induction Furnace Components such as; Coil Support Posts, Coil Liners, Furnace Tops, Bases, Front and Back Plates

  • Electrical Terminal Blocks and Supports for Electrical Resistor Grids Operating In High Temperature Environments

  • Exterior Structural Insulation In High Temperature Electrically Heated and Gas Fired Furnaces

  • Hot Face Structural Insulation In Glass Tempering And Annealing Furnaces

  • Brazing Separators and Fixtures

  • General Protective Heat Shielding in Foundry Environments

  • Insulation In High Pressure Molding Presses

  • Hearthplates and Furnace Shelving.
