High temperature fiber system with controlled shrinkage and stress resistance

摘要

An apparatus for lining the interior of a furnace or the like having a hot and a cold face comprising alternating strips of two fibrous materials stacked edgewise to form the insulative module or mat. The first fibrous material exhibiting either greater shrinkage or corrosion resistance than the second fibrous material, and the alternating pattern allowing the lining to be used in conditions which would normally exceed the use characteristics of the second material.
