Refractory Sheet Type RS-A0 pages

MOLDABLE BLANKETS
Types RS-A, RS-B, RS-C, RS-CH
and SI MOLDABLE
ZIRCAR's Refractory Sheet Type RS-A Moldable is a
tough ceramic fiber reinforced insulation which contains
no asbestos. Developed for induction coil liners and molten
metal transport, Refractory Sheet Type RS-A Moldable is
ideally suited for a wide range of high temperature, high
thermal shock applications. It is also used for brazing
separators and fixtures for jewelry making, as well as a
high temperature gasket material. Its high Alumina (Al2O3)
content makes it resistant to sticking in many
environments, including molten metals, and it has a
maximum operating temperature of 1450°C (2642°F).
Refractory Sheet Type RS-A Moldable is a wet blanket
that can be easily formed into a wide variety of simple and
complex shapes. Drying results in a strong rigid shape
that can be re-wet to restore the original moldability. Baking
irreversibly removes the moldability, leaving Refractory
Sheet Type RS-A Moldable rigid and unaffected by
moisture. Refractory Sheet Type RS-A Moldable can be
frozen and thawed repeatedly with no loss in moldability
or other properties.
Refractory Sheet Type RS-A Moldable can be dried rapidly,
either with a torch or by applying directly to a hot furnace,
to make quick repairs of cracks, or to replace missing
refractories.

Open plastic covering and unroll the desired amount of Refractory Sheet Type RS-A Moldable.
Cut to size with a knife.
Dry on a rigid glass, wood or metal plate separated by a piece of plastic, cloth or paper.
Prevent warping by either restraining or flipping over to allow drying from both sides.
Select a smooth mandrel of the desired size and shape.
Wrap mandrel with a plastic sheet.
Cut enough Refractory Sheet Type RS-A Moldable off roll to make desired shape.
Cut a bevel on the leading edge of the Refractory Sheet Type RS-A Moldable with a knife.
Wrap Refractory Sheet Type RS-A Moldable around mandrel.
Work joints together with a tool, such as a screw driver or knife to achieve as much fiber to fiber
interlocking as possible.
Make a plaster mold with sufficient draft to allow for the removal of the formed part.
Form Refractory Sheet Type RS-A Moldable onto or into mold by hand.
Dry until firm, then remove from mold and complete drying.
Large complex shapes can be made on any sort of removable form by joining sheets together with
a screwdriver or knife to achieve as much fiber to fiber interlocking as possible.
