GENERAL INFORMATION
| ZRCI Refractory Sheet
Type RS-200 is a fiber-reinforced ceramic laminate with useful properties to
1260캜 (2300캟). This high temperature product offers high strength, moderate
thermal conductivity and excellent electrical insulation. It retains its
strength and utility to levels far exceeding maximum use temperatures of
reinforced plastics and asbestos cement replacements. RS-200 is 100% inorganic,
non-flammable and contains no asbestos. Its high alumina content makes it
resistant to many environments including molten aluminum. RS-200 undergoes
little or no outgassing on heating, is not brittle, and may be cut and machined
with standard tooling. RS-200 is available in standard and custom boards and is
useful as Specialty Furnace Components, Specialty High Temperature Electrical
Thermal Insulation, Metal Working Components and Induction Furnace
Components. |
Compared to ZRCI Refractory Sheet Type
RS-100 , RS-200 has the following attributes:
- Finer reinforcement structure which allows for machining of
intricate detail
- Less tendency to delaminate
- Higher strength
Refractory Sheet Type RS-200 material is available in
Cylinder form as Refractory Sheet Cylinders Type
RS-201. |
SUGGESTED APPLICATIONS
-
Type RS-200 is the ideal TransiteTM and
asbestos-cement board replacement.
-
Type RS-200 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-200 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-200 is use in Non-ferrous metal handling
as spouts, troughs, and casting tips.
-
Type RS-200 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 1260캜 (2300캟).
-
Type RS-200 is used as an electrical insulator
for induction pressing of diamond saw segments.
-
Type RS-200 is used for Brazing separators and
fixtures. The high Al2O3 content makes it resistant to
sticking in many environments including molten metals.
-
Type RS-200 is used in the glass industry as dead
plates, set out plates, wear guides and pusher pads in hot glass
handling.
