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 1650캜 (3002캟) and is able to withstand over
500 hours continuous submersion in molten aluminum at 750캜 (1382캟) 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 300캜 (570캟) 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.
