Insulating Fiber
Superwool® Plus™ high-temperature fiber insulation is ideal
for repairing and lining aluminum furnaces, and it reduces the frequency of
relining operations when compared to the industry standard. Improved insulation
efficiency also results in decreased operating costs. Superwool Plus has been
engineered to maximize the fiber content. As a result, its insulating fiber has
up to 20% lower thermal conductivity than competitive fiber insulation
materials. The maximized fiber content reduces radiant heat transfer, making
Superwool Plus insulation an excellent choice for lining heat-treat furnaces for
aluminum and other nonferrous metals and homogenizing furnaces for aluminum
casters. Superwool insulating fibers are also non-wetting to molten aluminum.
This reduces the concerns about metal adherence and penetration into the
fibers.
