Refractory Sheet Cylinder RS 101 and RS 102

General Info

ZRCI Refractory Sheet Type RS-201 and RS-202 are fiber reinforced ceramic laminate with useful properties to 1260°C (2300°F). These high temperature products offer high strength, moderate thermal conductivity and excellent electrical insulation. They retain their strength and utility to levels far exceeding maximum use temperatures of reinforced plastics and asbestos cement replacements. They are 100% inorganic, non-flammable and contains no asbestos. Their high alumina content makes them resistant to many environments including molten aluminum. RS-201 and RS-202 undergoes little or no outgassing on heating, are not brittle, and may be cut and machined with standard tooling. RS-201 has a highly burnished outside surface. This is ideal when the OD is crucial for liner placement. RS-202 has an as formed surface. They are available in standard and custom size cylinders and are useful as induction coil liners, induction furnace components, and molten metal transport tubes.

Compared to ZRCI Refractory Sheet Type RS-101 Cylinders , RS-201 has the following attributes:

  • Finer reinforcement structure which allows

  • for machining of intricate detail

  • Less tendency to delaminate

  • Higher strength

Refractory Sheet Material is available in board form as Refractory Sheet Type RS-200
