FOREHEARTHS
HarbisonWalker International
has a long history of supplying
RVBMJUZ TQFDJBMUZ TIBQFT UP UIF
glass industry for forehearths.
®
In fiberglass furnaces, Serv
products are for glass-contact
materials, while in all soda-lime
superstructure applications, Nike
S65W products provide excellent
alkali resistance. HWI’s newest
addition to solutions for fore-
hearths in the soda-lime furnace
®
is Taycor M DC. This product
is a 99% alumina shape that
rivals the performance of fused
cast refractories while permitting
novel design solutions for the
forehearth.

INSULATION
HarbisonWalker International
has a variety of insulating prod-
ucts to lower thermal conduc-
tivity and improve operations.
®
HWI’s Inswool ceramic fiber
blanket products provide opti-
mum handling strength and low
heat storage, are easy to install,
and are resistant to thermal
®
shock. The Inswool ceramic
fiber blankets are offered in
temperature classifications up
to 2600°F. HWI insulating fire-
bricks (IFBs) are manufactured
with a porous structure that also
produces low thermal conduc-
tivity and good thermal shock
characteristics, resulting in top-
level insulating properties. The
IFBs have excellent strength
at operating temperatures and
resistance to corrosive alkali
environments. IFBs are offered
in a variety of temperature grades
and densities.

®
laboration to produce the Tiger
