A ceramic fiber modular assembly for lining walls of furnaces is disclosed. The modular assembly comprises stacked strips of ceramic fibers and a refractory steel anchoring system. The anchoring system comprises two platelike lateral member which protrude parallel to the ceramic fiber strips with teeth projecting from both sides by the lateral members. One of the lateral member is rigidly fixed to a platelike central member and the other admits of translation relative thereto. An aperture in the central member permits securement to the wall of the furnace. During manufacture the modular assembly is partially wrapped in packaging material tied with straps, applying compression to the fibers. The packaging material is removed prior to installation of the modular assembly. When installed tight fitting contiguous modular assemblies exert compression on the fibers.
In a ceramic fiber modular assembly for lining walls of furnaces or other high temperature chambers, said modular assembly comprising stacked ceramic fiber strips in generally parallelepiped configuration and a refractory steel anchoring system for holding said strips and securing said modular assembly to the wall to be lined, the improvement consisting of providing an anchoring system comprising:
A method for installing modular assemblies for lining steelwork walls of a furnace or other high temperature chamber, in which each said modular assembly comprises stacked ceramic fibers strips in generally parallelepiped configuration and a refractory steel anchoring system for holding said strips and securing said modular assembly to the wall to be lined, said anchoring system of said modular assembly comprising two lateral members engaged in one face of said modular assembly, each of said lateral members defining a plate oriented parallel to said fiber strips and including perpendicular protrusions attached to the interior of said modular assembly by perpendicularly projecting into said strips adjacent said lateral members, a central member disposed perpendicular to said lateral members and attached therewith, said central member defining a plate bearing flatwise against said one face of said modular assembly and having an aperature for securement to the wall to be lined, packaging material partially wrapping said modular assembly, exposing said one face thereof and temporarily maintaining said fibers of said strips under compression;
