For manufacturing insulating castables.
irregular spaces where other types of refractories are
difficult to use.
For covering steel ingot hot
tops and risers in ferrous and non ferrous foundries.
Blazelite insulating aggregates
are available in different chemical compositions for
different temperature functions. They are also
available in two different gradations.
Can be combined with shipments of
other materials from the Zelienople plant to reduce
freight charges. Installation as loose fill is
quick - reducing labor costs versus other refractories.
Produced under rigorous quality standards by the same
process used in manufacturing insulating fire brick.
two numbers in the following Blazelite aggregates
designations refer to the refractories or heat
reststance of the aggregate. The second two
numbers refer to the approximate density of the slab.
An LI designation means it low in impurities of ferric
oxide and titania. The LI designated aggregates
are suitable for use in reducing atmospheres when
combined with low iron calcium aluminate cements.
Can be combined with portland cement or
calcium aluminate cements to produce a low-density,
low-temperature insulating castable for 2300°F
service or below.
A lower density version of 2653 LI used for the
very lightest castable in the 2400 to 2600°F
A high purity material for temperatures of 2400
used extensively for low-iron insulating castables.
Used as a high temperature filler material and
for the lightest weight high temperature castables.
Its high purity is absolutely necessary for high
An alternate to 2855 LI, it is used when a
higher strength insulating castable is desired.
