In theory, there exist two methods of replacement of traditional lining made of fireclay insulation articles by lining made of OKB Cerablanket refractory ceramic fiber. The first method consists in production of lining made of OKB Cerablanket rolled material with the material being formed in undulating fashion into sections with height of a wave equal to the thickness of the lining. In the second method, the lining is fabricated from ready-made modular Z-blok sections with integrated anchors made of stainless steel. Sections fabricated from OKB Cerablanket rolled material is arranged in a linear or checkerboard arrangement. The operating life of lining fabricated from refractory fiber is practically unlimited. Anumber of conditions that guarantee long and effective service of the materials must be fulfilled, for example, the furnace temperature must not exceed 1170°C, rate of gas flow must not be greater than 20 – 30 m/sec, and the lining must not be subjected to mechanical loads.
