According to different molding methods, ceramic fiber modules can be divided into folding blocks, slice blocks, Palo blocks, and vacuum forming blocks. Due to the different production methods of polycrystalline mullite fibers and their different crystal orientation structures, their fiber lengths are short and their flexibility is poor, so they cannot be made into large modules, resulting in the failure of large-scale applications of polycrystalline fibers. Nowadays, polycrystalline mullite fibers are mostly used in castables or refractory brick furnace walls and the inner surface of the furnace roof. The use of polycrystalline fibers can effectively reduce the temperature of the outer wall of the furnace and reduce the heat storage loss of the furnace wall.

At present, most domestic ceramic fiber manufacturers produce ceramic fiber folded blocks. First, use a needle-punched blanket to fold, and use mechanical equipment to pre-press the ceramic fiber module during molding. The production method causes uneven surface to affect the spraying effect of the anti-scouring coating. The slice block is improved on the basis of the ceramic fiber folded block. The manufacturing method of the slice block is to cut off the fold after the folded block is formed to make the cut surface flat.
