● A series of ceramic fiber folded module was processed according the fiber module structure、size by special machine on the ceramic fiber needle blanket which was corresponding material. In the course of processing, they should be maintained a certain proportional reduction, to ensure that compressed to form a integer set without joint between ceramic fiber folded blanket after ceramic fiber folded module have been built. Owing to the ceramic fiber folded module expand differently. Ceramic fiber folded module could be fixed to the stud which in the steel board of industrial furnace by series of anchors.
