GENERAL INFORMATION
|
ZIRCAR Refractory Sheet Type RS-99 is a high density fiber based ceramic material with greater than 99% alumina purity. Type
RS-99 has strength equal to asbestos cement and therefore is an excellent replacement for asbestos cement materials. Refractory Sheet Type
RS-99 is usable to temperatures of 1650°C (3002°F) and is able to withstand over 500 hours continuous submersion in molten aluminum at
750°C (1382°F) with no wetting and no degradation in properties. Type
RS-99's high
alumina content is ideal for high vacuum, reducing atmospheres, and other applications where silica cannot be tolerated. Refractory Sheet
RS-99 boards are available in four types:
|
- Type RS-99M is a plastic highly moldable sheet ideally suited for forming custom geometries.
- Type RS-99W boards can be moistened with water and molded into any desired shape. After low temperature bake-out of
300°C (570°F) boards are unaffected by moisture.
- Type RS-99R boards are prefired and are unaffected by moisture. They stay rigid even if saturated with water.
|
SUGGESTED APPLICATIONS
Type RS-99 is the ideal TransiteTM and asbestos-cement board replacement.
Type RS-99 is used as a high and low temperature electrical insulator.
Type RS-99 is used for brazing separators and fixtures. The high Al2O3
content makes it resistant to sticking in many environments including molten metals.
Type RS-99 is used in the glass industry as dead plates, set out plates, wear guides and pusher pads in hot glass handling.
Type RS-99 is used as induction furnace components such as channel melter components, coil liners, coreless induction components, covers, tops, bases, front and back plates, coil supports, splash and coil shield.
Type RS-99 is used for rapid cycle furnace door cowls and hot face supports.
Type RS-99 is used as a high and low temperature
gasketing.
Type RS-99 is use as non-ferrous metal handling as pouring spouts, troughs, and casting tips.
