REFRACTORY SHEET TYPE
RS-100 |
|
GENERAL INFORMATION
ZIRCAR Refractory Sheet Type RS-100 is a ceramic
fiber reinforced structural alumina composite material with useful properties to
1260°C (2300°F). It has exceptional flexural and compressive strengths in the
range of high temperature reinforced plastics such as G-7 and G-10 laminates and
retains strength and utility to levels far exceeding maximum use temperatures of
plastics. Mechanical properties of Type RS-100 sheet far exceed those of
TransiteTM and other asbestos-cement materials and is an excellent replacement
for these rigid asbestos-containing products. Type RS-100 can also be employed
at much higher temperatures than these types of products.
Type RS-100 is 100% inorganic, non-flammable and
contains no asbestos. Its high Al2O3 content makes it
highly resistant to many environments, including molten aluminum. It undergoes
little or no outgassing on heating. It is not brittle and has high impact
properties. Type RS-100 may be cut and machined with standard tooling. Type 100
sheet is used both as a full-size panel and as a source for precision-cut
fabricated components.
Refractory Sheet Material is available in
Cylinder form as Refractory Sheet Type RS-101
Cylinders. |
SUGGESTED APPLICATIONS
-
Type RS-100 is the ideal Transite TM and
asbestos-cement board replacement.
-
Type RS-100 is ideal for specialty furnace
components such as bottom supports for quartz furnaces, furnace shells with
element feed throughs and low temperature kiln and oven walls.
-
Type RS-100 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 shields.
-
Type RS-100 is use in Non-ferrous metal handling
as spouts, troughs, and casting tips
-
Type RS-100 is the ideal material for use as
electrical terminal blocks and electrical resistor grids, due to its good
electrical resistivity, good mechanical strength and its ability to withstand
temperatures to 1260°C (2300°F).
-
Type RS-100 is used as an electrical insulator
for induction pressing of diamond saw segments.
-
Type RS-100 is used for brazing separators and
fixtures. The high Al2O3 content makes it resistant to sticking in many
environments including molten metals.
-
Type RS-100 is used in the glass industry as dead
plates, set out plates, wear guides and pusher pads in hot glass
handling. |
