ABSTRACT:
A refractory and insulating module for use in lining a furnace or other high temperature enclosure comprises a block having a front wall and side walls the outer faces of which side walls are inclined inward from front to back of the block, the rear of the block being open to provide a cavity. The front face of the front wall of the block is of lower density than the rear face of the front wall. The block is produced from a ceramic fiber slurry using a suction technique in conjunction with a mould shell which forms every face of the block except the front (hot) face of the front wall, the shell being formed with multiple apertures. The rear cavity may accommodate layers of other insulating materials according to the temperatures to be withstood and the temperature gradient to be achieved. The block can be secured to a furnace casing by means of fastening elements which are pushed into the outer sides of the side walls of the block. Adjoining blocks are sealed with respect to each other by a sealing fabric nipped between the edges of the front faces of the blocks.
