REFRACTORY MATERIALS
Refractory materials
REGENERATOR WALLS
AND CROWNS;
UPPER DIVISION WALLS
This section of the regenera-
tor must resist solid carryover
attack and is typically subjected
to higher temperatures. Careful
consideration of insulation being
used on crowns must be taken
regarding hot-face temperature
and expected mean temperature
of the hot-face refractory:
t /JLF 4 )' )JHI BMVNJOB
with superior creep resistance
®
t 4VQFS /BSNBH HF 96%
MgO with excellent creep
resistance
t /JLF 4 8 )JHI BMVNJOB XJUI
excellent alkali resistance
®
t /BSNBH 50 DBRG 50%
MgO direct-bonded magnesite

t 6GBMB 60% alumina brick
TARGET WALLS
Regenerator target walls expe-
rience extreme conditions from
batch carryover. Issues are most
severe in end-port furnaces and
the first two or three ports in
side-port furnaces. HWI prod-
ucts for this area:
®
t (FN A high-alumina, fused
mullite brick with excellent
refractoriness and creep resist-
ance
®
t 7JTUB Sintered AZS with high
resistance to alkali attack
t /JLF 4 )JHI BMVNJOB XJUI
high strength and good creep
resistance
t /JLF 4 8 )JHI BMVNJOB XJUI
excellent alkali resistance
®
t /BSNBH VZ Mag-zircon com-
position with a forsterite bond
®
t 4VQFS /BSNBH B Burned
96% MgO with improved creep
resistance
