patching rat holes, thin spots,

well as providing a monolithic
seal layer.

Middle walls
(Roughly 2-10 feet below the
top checkers) This section of
the regenerator is exposed to
lower temperatures, with rela-
tively minor thermal cycling. The

the refractory selection is resist-
ance to creep. Products to be
used here:
®
t 4VQFS /BSNBH B Burned
96% MgO with improved creep
resistance
®
t 6GBMB 9$3 "M 0 XJUI
increased creep resistance
t /JLF "3 "M 0 GPS
increased resistance to conden-
sate
®
t ,BMB 6OJRVF BMVNJOB
brick with outstanding alkali
and creep resistance

Lower walls
Like the lower checkers, this
section is exposed to temperature
cycling and sulphate condensate
that can be an issue. In addition,
creep resistance is critical in this
application due to the increased
load on the refractory.

HWI BOTTOM CONCEPTS
Vision ®
A sintered AZS material is
chosen over Fused Cast AZS
due to its engineering properties,
including linear thermal expan-
sion, higher electrical resistivity,
no glassy phase, uniform density,
®
and a lower k-factor. Vision
and the HWI bottom concept
offer glassmakers the best of both
